怎么打jar包 jar怎么运行

一、怎么打jar包

第一步：选中要打jar包的工程

第二步：鼠标右击，选择Export...

第三步：选择java中的Runnable JAR file（如图）

点击“Next” 

第四步：（1）在Launch configuration：选择要打jar包的mian所在的类名；（如图）

 

            （2）在Export destination：选择要存放jar的名称和地址（如图）

 

      （3）如果要打的jar包需要调用别的jar包 请选择Library handling：中copy required libraries into a sub-folder next to the generated JAR（如图）

 第五步：点击 “Finish”

二、运行 jar 方法

（1）cmd

（2）java -jar 盘:\文件名\XXXX.jar

请问，如果我里面写成循环执行，执行jar包，那要怎么结束

感谢LZ，终于搞定了eclipse导出jar，并且在dos里面可以运行了

把jar包复制到另一路径下再运行，看行不行？
