We use threads in Java(actually in whole programming) to execute parallel or distributed process at the same time.

More simply, think about a users data entry system. Once a user enter his/her data system need to process it. It may take little time. Until that process is completed system cannot get others data, if you are working on a single routine. Using multiple threads what we can do is, collecting data and processing data can be done in two phrase, without disturbing to each other.

You cannot write programming without using threads in Java. Even you implement runnable interface or extended the Thread class, main method always run on a thread.

You can *write* a program without threads
however you cannot run a program without using threads.

Fortunately, you can write and run programs without worrying about threads being there. You can get a long way without using Threads explicitly.

Yes, I've miss the word. You can write program without threads, but cannot runt without them.
