Work With Jar File

Extracting the Contents of a JAR File

The basic command to use for extracting the contents of a JAR file is:

jar xf jar-file [archived-file(s)]

Suppose you want to extract the TicTacToe class file and the cross.gif image file. To do so, you can use this command:

jar xf TicTacToe.jar TicTacToe.class images/cross.gif

now you want to extract the TicTacToe all file to the current directory

jar xf TicTacToe.jar
