Answer 1

如果您安装了WinRar或WinZip软件，则只需在jar文件上单击鼠标右键，然后单击“解压缩”即可在此处使用jar文件的所有内容。

Answer 2

通过使用以下解压缩任务，可以使用Ant脚本轻松完成此操作： http : //ant.apache.org/manual/Tasks/unzip.html

Just do a little research could help a lot. You can open a .jar file using winRAR then decompile the .class file as stated here How do I "decompile" Java class files?

To recompile you can use 'javac' in command prompt provided you listed all the classpath necessary. How to compile a .java file in Java?

then you can overwrite the file in .jar
