Extracting .jar file with command line

Question

I am trying to extract the files from a .jar file. How do I do that using command line?

I am running Windows 7

Answer 1

Given a file named Me.Jar:

1. Go to cmd
2. Hit Enter

3. Use the Java jar command -- I am using jdk1.8.0_31 so I would type

   C:\Program Files (x86)\Java\jdk1.8.0_31\bin\jar xf me.jar

That should extract the file to the folder bin. Look for the file .class in my case my Me.jar contains a Valentine.class

Type java Valentine and press Enter and your message file will be opened.

Answer 2

To extract the jar into specified folder use this command via command prompt

C:\Java> jar xf myFile.jar -C "C:\tempfolder"
