Thread in Java

What is Thread?

Thread is a class, an independent path of execution within a program. A thread execute the provided code(Task) in new process, so the thread run concurrently with your program. 
Usually thread is use for connectivity(i.e. Networking, Internet, Bluetooth), timer, i/o operation.
It can be extends with your program, and a run method must be override, and that override method run when thread starts.
Thread class is define in:  java.lang.Thread

When thread object is made then a runnable object must pass inside thread object. I discuss runnable object in next lesson.


class ThreadTest extends Thread
     public void run()
           System.out.println("Thread starts...");
     public static void main(String args[])
          ThreadTest t=new ThreadTest();
