Java Features (Multithreaded)

   Java Is Multithreaded

A thread is like a separate program, executing concurrently. We can write Java programs that deal with many tasks at once by defining multiple threads.

                                                          OR

Multithreading is a Java feature that allows concurrent execution of two or more parts of a program for maximum  utilization of CPU. Each part of such program is called a thread. So, threads are light-weight processes within a process. 

The main advantage of multi-threading is that it doesn't occupy memory for each thread. It shares a common memory area. Threads are important for multi-media, Web applications, so on.
