Easiest way to unpack a jar in java

Question

Basically, I have a jar file that i want to unzip to a specific folder from a junit test.

What is the easiest way to do this? I am willing to use a free third party

Answer 1

Jar is basically zipped using ZIP algorithm, so you can use winzip or winrar to extract.

If you are looking for programmatic way then the first answer is more correct.
