请在JAD主页阅读此免责声明；

1. Installation.

安装.

Unzip jad.zip file into any appropriate directory on your hard drive.

解压缩jad.zip到任意合适硬盘文件夹下。

This will create two files:

创建两个文件夹：

- an executable file named 'jad.exe' (Windows *) 可执行文件

or 'jad' (*n*x)

- this README file

No other setup is required.

不需要其他的设置

2. How to use Jad

怎么样使用JAD

To decompile a single JAVA class file 'example1.class'

type the following:

下面介绍反编译一个简单的class文件

jad example1.class

This command creates file 'example1.jad' in the current directory.

If such file already exists Jad asks whether you want to overwrite it or not.

Option -o permits overwriting without a confirmation.

这个指令在当前文件夹下创建'example1.jad'的文件

如果这样的文件已经存在，JAD会询问是否对此文件进行重写。

选项-o 允许重写不需要进行确认。

You can omit .class extension and/or use wildcards in the names of

input files.

对于输入文件名你可以省略 .class扩展或者利用通配符

Option -s <ext> allows to change output file extension:

选项 -s允许改变输出文件扩展：

jad -sjava example1.class

This command creates file 'example1.java'. Be careful when using

options -o and -sjava together, because Jad can accidentally overwrite

your own source files.

这个指令创建'example1.java'文件。特别注意当你同时使用-o和-s选项时，因为JAD会偶然重写你的资源文件。

Jad uses JAVA class name as an output file name. For example, if class

file 'example1.class' contains JAVA class 'test1' then Jad will create

file 'test1.jad' rather than 'example1.jad'. If you want to specify

your own output file name use the output redirection:

JAD利用JAVA类的名字作为输出文件的名字。例如，如果'example1.class'文件中包含JAVA类'test1'，Jad会创建文件名字为'test1.jad'而不是'example1.jad'。如果你想要指定具体输出文件名字可以使用输出重定向指令：

jad -p example1.class > myexm1.java

Option -d allows you to specify another directory for output files,

which are created, by default, in the current directory. For example:

选项-d允许你为输出文件指定另外一个文件夹，此文件夹默认在当前文件夹下创建。

jad -o -dtest -sjava *.class

(or jad -o -d test -s java *.class, which has the same effect)

此指令和上一指令有同样的作用。

This command decompiles all .class files in the current directory

and places all output files with extension .java into directory 'test'.

这个指令反编译所有的class字节码文件并且把所有输出文件名添加.java扩展名然后放置在当前文件夹下的test文件夹下。

If you want to decompile the whole tree of JAVA classes,

use the following command:

如果你想反编译整个树型class字节码文件，请利用下面的指令：

jad -o -r -sjava -dsrc tree/**/*.class

This command decompiles all .class files located in all

subdirectories of 'tree' and creates output files in subdirectories

of 'src' according to package names of classes. For example, if file

'src/a/b/c.class' contains class 'c' from package 'a.b', then

output file will have a name 'src/a/b/c.java'.

这个指令反编译src所有树型子文件夹下所有class文件并且根据字节码文件的路径命名输出文件名字。例如'src/a/b/c.class'包含字节码文件c，输出文件c.java就在'src/a/b/c.java'

Note the use of the "two stars" wildcard ('**') in the previous

command. It is handled by Jad rather than the command shell, so on

UNIX the last argument should be single-quoted:

请前一条指令中的注意两个星('**')的通配符，它被JAD处理，并不是指令脚本，所以在UNIX系统中后一个参数应该是使用单引号的

jad -o -r -sjava -dsrc 'tree/**/*.class'

In a case you want to check the accuracy of the decompilation or just

curious, there is an option -a which tells Jad to annotate the output

with JAVA Virtual Machine bytecodes.

万一你想要检查反编译的准确性或者仅仅是出于好奇，-a选项可以使Jad注释JAVA虚拟机输出的字节码。

Jad supports the inner and anonymous classes.

When Jad expands wildcards in the input file names,

it automatically skips matching inner classes.

On UNIX Jad skips inner classes if there is more than

one class specified in the command line.

Jad looks for inner classes in the directory of their top-level

container class.

Jad支持内部类和匿名类。当Jad输入文件名字中扩展通配符，它会自动的跳过匹配内部类。在UNIX 如果在指令中超过一个指定的类Jad 会跳过内部类。
