>Solution :

You can create new Thread, define what it should do and start it.

Docs:

https://docs.oracle.com/javase/7/docs/api/java/lang/Thread.html

Check docs for java version you need. These are for version 7.

Also I suggest you to get some knowledge about parallel programming and using threads. There are plenty of material on the internet
