JDK explain the order (2)

Keytool

Features:
Management and certification by the private key related to the X.509 public key certificate chain composed of key stores (database). Management also a certificate from a trusted entity.
Syntax:
Keytool [command]
Supplementary information:
Keytool is a key and certificate management tool. It enables users to manage their own public key / private key pairs and the relevant certificate for (through digital signatures) self-certification (user to other users / services certification itself) or data integrity and authentication services. It also allows users to store their communications, such as the public key (in the form of a certificate).

Native2ascii

Features:
The local code will contain characters (neither Latin1 and non-Unicode characters) documents into Unicode character encoding of documents.
Syntax:
Native2ascii [options] [inputfile [outputfile]]
Supplementary information:
Java Java compiler and other tools which can only deal with Latin-1 and / or Unicode encoding (udddd mark) characters in the document. Native2ascii will contain other character encoding of the document into Latin-1 and / or Unicode character encoding of documents. If omitted outputfile, using standard output device output. In addition, if inputfile Thus, the use of standard input device input.
Order options
On the contrary-the implementation of the reverse operation: with Latin-1 and / or Unicode character encoding of the document into local coded character document.
- Encoding [encoding_name] process of the change of use of the designated code name. Default coding from the system attribute file.encoding be.

Appletviewer Appletviewer

Features:
Java applet browser. Appletviewer orders to be out of the World Wide Web browser running environment of the applet.
Syntax:
Appletviewer [threads flag] [command option] urls …
Supplementary information:
Appletviewer orders connected to the url at the documents or resources, and in its own window display documents cited each applet. Note: If the url points to a document does not invoke any OBJECT, EMBED or APPLET marked applet, then appletviewer not do anything.
Order options
- Debug Java debugger in the initiation of appletviewer jdb, so you can debug files in the applet.
- Encoding [code name of the designated input coding HTML file name.
- J [javaoption] javaoption string passed as a single parameter of the operation appletviewer Java interpreter. Parameters can not contain spaces. By the string composed of multiple parameters, each of these parameters must be prefix - J beginning, the prefix, will be removed. This adjustment in the implementation of compiler environment or memory usage will be very useful.

Extcheck

Features:
Extcheck detect target jar files with the current installation of the expansion of the jar file version conflicts.
Syntax:
Extcheck [-verbose] targetfile.jar
Supplementary information:
Extcheck practical inspection procedures specified Jar and the title of the document with JDK TM version of the software installed in the expansion of whether there is a conflict. In the expansion of a pre-installed can be used to see if the utility has been installed in the expanded version of the same or higher version.
Extcheck practical procedures will targetfile.jar list of documents the specification and specification-title-the first version installed in the expansion of the current directory of all documents relative Jar should be the first to compare (the default directory for the expansion jre / lib / ext). Extcheck comparison utility version of the way java.lang.Package.isCompatibleWith method. If not detected conflict, the return code is 0. If any expansion of a jar in the directory of a list of documents have the same title and the same specification-or-updated version of the specification, non-zero return error code. If targetfile.jar no specification of the list of title-or-specification version attributes, the same non-zero return error code.
Order options
- Verbose on the expansion of the directory Jar document examination, the paper listed. In addition, the report documents a list of goals jar and attribute all conflicts jar files.

Jar

Features:
Java syntax archiving tool:
Jar [options] [Order manifest] destination input-file [input-files]
Supplementary information:
Jar is a tool for java applications, multiple files can be merged into a single JAR archive documents. Jar is a multi-purpose compression and archiving tool, which is based on ZIP and ZLIB compression format. However, the main purpose of design jar is easy to java applet or application into a single package archiving documents. Applet or application will be the components (. Class files, images and sounds) into a single archive file, you can use java agents (such as browsers) in a HTTP transaction processing in the process of downloading them, rather than for each components are calls for a new link. This has greatly shortened the download times. Jar also compressed files, thus further improving the download speed. Furthermore, it allows the author applet in the document of the various signature, which would certify their sources. Jar tools tar command syntax is basically the same syntax.
Order options
- C in the standard output on the creation of new archiving or archiving space.
- T in the standard output of the contents listed on the table.
- X [file] from the standard input from all the documents, or only from specified documents. If omitted the file, extract all the files, otherwise only from the designated document.
- F second parameter designated to handle jar files. In - c (creation) cases, the second parameter that is to create a jar file name (not the standard output.) In - t (Table (or - x (extraction) in both cases, the second parameter should be set out or documents taken from the jar.
- V standard error output devices endogenous growth of the output format.
- M including the designation of the existing list of the inventory information in the document. Usage Example: "jar cmf myManifestFile myJarFile class *."
-0 Only storage, no ZIP compression.
- M projects do not create a list of documents.
- U by adding document or list of changes to update the existing JAR file. For example: "jar-uf foo.jar foo.class" foo.class document will be added to the existing JAR file foo.jar, "jar umf manifest foo.jar" is used to update the information in the manifest of foo.jar list.
C-jar order in the implementation of changes during the directory. For example: "jar-uf foo.jar-C classes *" directory of all classes Add foo.jar document, but do not add a category directory itself.
Examples of procedures
1: The current directory of all documents CLASS JAR packaged into a new document:
Jar cf file.jar class *.
2: An JAR files in the file list
Jar tf file.jar
3: Under the current directory of all documents to an already existing document JAR
Jar cvf file.jar *

Javadoc

Help
Java API documentation generator from Java source files generated API documentation HTML page.
Syntax:
Javadoc [order] [options] [packet source document files] [@]
One [package name] for a series of space separated by the name of Bao Bao were not allowed to use wildcards, such as (*). [Source file name] for a series of space separated by the source file name, the source file name and path can include wildcards, such as (*). [@ Files] in any order and contain packets of a source file or multiple files.
Supplementary information
Javadoc analytical Java source files and documents in the statement notes, and a corresponding default HTML pages), describes the public category, protected class, the internal category, interface, constructor, method and Victoria.
In the achievement, and Javadoc request java compiler dependent on the completion of its work. Javadoc javac compiler statement calling some of the overlooked members to achieve. It is built like a variety of internal said, including the level and type "use", which then generate HTML. Javadoc from the source code files Notes users access to the documents.
When establishing its internal documents Javadoc structure, it will load all the categories cited. As this point, Javadoc must be able to find all cited categories, including guide category, extensions and user categories.
Order options
- Overview i> path / filename should be designated javadoc path / filename specified in the "source" documents outlined in the document access, and outlined it to the page (overview-summary.html). Which path / filename is in contrast to - sourcepath the relative pathname.
- Public display only category and members of the public.
Show-protected only by the protection and public and members of the class. This is the default state.
- Package show only package, and the protection of the public and members of the class.
- Show all categories and private members.
Online help-help show, which will set out these javadoc and doclet command-line options.
Doclet class-designated start to generate documentation of the types of documents docle. The doclet defined the content and format of the output. If you do not use - doclet option, javadoc doclet generated using standard default HTML format. These must include start (Root) Act. The start of the path from - docletpath options definition.
- Docletpath classpathlist designated doclet the path of documents, such document use - doclet option to specify. If doclet search has been located in the path, there is no need to use this option.
-1.1 Generated a 1.1 Javadoc generated by the appearance and functionality of document files. In other words, the page background gray, so header by image, the use of bullet list rather than form a single purpose of the directory structure, the API does not include inheritance, not to? *** TML framework, and does not support the internal category . This option also will be indexed automatically separated into individual letters of a document. If you want to look this, then this option than javadoc equivalent to 1.1 advantage that some mistakes.
- Sourcepath sourcepathlist
When a packet will be transmitted to the javadoc order, the designated location source files (. Java) search criteria. Javadoc attention only when ordered by the name of the designated packet can be used sourcepath options - it will not find in the order transmitted to the javadoc. Java document. If omitted - sourcepath, javadoc use of trails by source.
- Classpath classpathlist designated View javadoc which will be used in the path of - quote category refers documents with the class with their use of any type. Javadoc will search designated trails all subdirectories. Classpathlist may include multiple paths each separated by a comma.
- Bootclasspath classpathlist bootstrap type of designated trails. They name of the Java platform. This is Javadoc bootclasspath will be used to find the source and type of document part of the search path. In classpathlist with a colon (:) separate directory.
- Extdirs dirlist designated expansion of the directory. They are no mechanisms to expand the use of Java class. This is Javadoc extdirs sources will be used to find files and documents in the part of the search path. Dirlist used in the colon (:) separate directory.
- Verbose javadoc in the running to provide more detailed information. Do not use verbose option, it will display the loading source files, generating documents (one each source file information) and the sort of information. Print options lead to verbose additional information, analytical each designated java source files of a few milliseconds.
- Locale language_country_variant designated javadoc files used in the generation of the environment.
- Encoding name of the designated source code, such as EUCJIS / SJIS. If you do not specify this option, then use the default platform converters.
- J [flag] flag will be transmitted directly to the runtime operation javadoc system java. J attention and can not have a space between the flag.
Options provided by the standard Doclet
D directory specified javadoc-generated HTML preservation of the purpose directory. Omit this option would lead to saving the file to the current directory. Directory which can be relative or absolute path of current working directory relative path.
- Belt use for each document type and packet includes a "use" page. Page description given of the use of any package or packages API, type, method, constructor function and Victoria. For a given category C, the use of the C category would include anything subclass C, the statement for the C domain, as well as methods to return C C type with parameters of structure and function.
- Generated version in the document, including text @ version. Default will be omitted from the text.
Author-generated documentation included in the @ author text.
- Splitindex in alphabetical index file will be split into multiple files, each letter a document containing all with a non-alphabetic characters to the beginning of the index of documents.
- Windowtitle [title] Add HTML <title> designated marker in the title. It will appear in the window title bar and the page is created by any browser bookmarks (favorite position). The title should not contain any HTML tags, because the browser will not be able to correctly interpret them. In the title of any internal quotation marks must be escaped. If omitted - windowtitle, Javadoc use of the option - doctitle value.
- Doctitle [title] in the designated place near the top of the overview paper outlining the title. The title will serve as a title, the center directly on the navigation column. Title and html tags can contain spaces, but if so, it must be enclosed in quotation marks. In the title of any internal quotation marks must be escaped.
- Title [title] this option no longer exists. It is the only Javadoc 1.2 Beta version. It has been re-named - doctitle. Rename this option in order to more clearly express its definition document title rather than window title.
- Header [header] designated placed in the top of each output file header text. The header will be placed on top of the right navigation column. Header can contain HTML tags and spaces, but if so then it must be enclosed in quotation marks. In the header of any internal quotation marks must be escaped.
- Footer [footer] designated place in each output file footnote at the bottom of the text. Scripts will be placed in the lower part of the right of navigation column. Footer and html tags can contain spaces, but if so, it must be enclosed in quotation marks. In the footer of any internal quotation marks must be escaped.
- Bottom [text] designated placed in the output file at the bottom of each text. The text will be displayed on the page at the end of navigation in the lower part of the column below. Which text can include HTML tags and spaces, but if so, it must be enclosed in quotation marks. In the text of any internal quotation marks must be escaped.
- Link [docURL] has been used to create links in the javadoc-generation external use of the document. DocURL parameters is to link to the outside javadoc-generated document URL. The location can be a relative or absolute URL.
- Linkoffline [] [packagelistURL docURL] options for external use of the name at the documents creating the link.
- Group [groupheading] packagepattern: packagepattern: … will be outlined on page packet into the designated groups, each with a table. Different - group option to specify each group. Each group designated by the command line appeared in the order pages. Group packages in alphabetical order. For a given - group options, and the list packagepattern expression matching package for groupheading appear in the title of the form.
- Nodeprecated prevent any generation in the document does not encourage the use of the API. It implementation - nodeprecatedlist doing things, and it is not generating any part of the remaining documents do not encourage the use of the API. When the code does not want to be prepared not to encourage the use of the code distraction, it is very useful.
- Nodeprecatedlist prevent the formation contained in document does not encourage the use of the API list (deprecated-list.html), and prevent the navigation bar contains links to the page. (However, javadoc to continue to generate the rest of the document does not encourage the use of the API.) If the source code does not contain not encourage the use of the API, and you want to navigation bar cleaner, it is very useful.
Notree-generated documents neglected / interface level. By default, it will have the level.
Noindex-generated documents neglected in the index. By default, the index will be generated.
- Nohelp output in the top and bottom of each page navigation column neglected to "help" link.
- NonaVBar nonaVBar prevent navigation column headers and footnotes, otherwise they will emerge in the generation of the top and bottom of page. Its "bottom" option does not affect. When only the interest and not the content of the necessary navigation, for example, only to convert documents to PDF or PostScript print, - nonavbar option is very useful.
- Helpfile [path / filename] designated top and bottom navigation bar to "help" link by link to the alternative help file path / filename path. Do not use this option, the help files automatically create Javadoc-doc.html help it in the hard-coded in the Javadoc. This option makes the situation can cover such default. Filename which can be any name is not restricted to help-doc.html - Javadoc will be adjusted accordingly navigation bar links.
- Stylesheetfile [path / filename] designated alternative HTML style sheets of paper trails. Do not use this option, the Javadoc will automatically create style sheets stylesheet.css document, which in the hard-coded in the Javadoc. This option makes the situation can cover such default. Filename which can be any name is not restricted to stylesheet.css.
- Docencoding [name] designated output HTML document coding.

Javah

Features:
Stub C header files and documentation generator. Javah generated from the Java class C header files and C source files. These documents provide the glue connecting to Java and C code can be interactive.
Syntax:
Javah [order options] fully-qualified-classname..
Javah_g [order options] fully-qualified-classname..
Supplementary information:
Javah generated for local approach, the C header files and source documents. C procedures generated by the source and header files in the local paper quoted a source object instance variables. . Struct h document contains a definition of the layout and the corresponding definition of the layout of the parallel. Struct in the domain corresponding to the class instance variables.
And the first file name in the first statement in the document were derived from the structure of a class name. If passed javah the category is in a package, the first file name and structure of the former should be called a packet. Underscore (_) for the name of separation.
Default, the javah the command line for each listed in the first category are the creation of a document and the document on the current directory. Use - stubs options to create source files. Use - o option to list all of the results connected in series to form a single document.
Default, the javah the command line for each listed in the first category are the creation of a document and the document on the current directory. Use - stubs options to create source files. Use - o option to list all of the results connected in series to form a single document.
Order options
