How can I make use of parallel in Java? Or do I use normal threads?

---

1. Read the Java Concurrency Tutorial.
2. Make multiple threads to do your work for you.

What a big topic! A typical solution is using multi-threading, you need a class implemented Runnable interface and put your function into its run() method. For details, I suggest you buy a copy of Java Concurrency in Practice.

You can use both Java Threads and Java Concurrency framework.

If you are really interested about Java concurrency, Java Concurrency in Practice is a good book to start.
