Java命令备忘录 - 解压和打包Jar，用得不多容易忘的两种命令，记录下。

## 1. 压缩 ##

## 压缩指定文件
    jar cvf filename.jar a.class b.class
    ## 全部压缩
    jar cvf filename.jar *

## 2. 解压 ##

## 解压test.jar到当前目录
    jar xvf test.jar

## 3. 参数 ##

   <td align="left">To extract the contents of a JAR file</td> 
   <td align="left">jar xf jar-file</td> 
  </tr> 
  <tr> 
   <td align="left">To extract specific files from a JAR file</td> 
   <td align="left">jar xf jar-file archived-file(s)</td> 
  </tr> 
  <tr> 
   <td align="left">To run an application packaged as a JAR file (requires the Main-class manifest header)</td> 
   <td align="left">java -jar app.jar</td> 
  </tr> 
 </tbody> 
</table>

jar后面的参数：

*  \-c : 创建压缩包
 *  \-v : 展示创建过程
 *  \-f : 指定文件路径
 *  \-x : 解压文件

上述这些参数与Linux上的tar命令参数一样的，tar的解压缩命令 -cvf/-xvf2 。
