Thread class inheritance

step

Thread define a subclass;
covering run process (thread execution event method);
creates an instance of the threads: Thread t = new MyThread (http://www.amjmh.com/v/BIBRGZ_558768/ );
start threads t1.start ;
example:

public class Main3 extends Thread{
int a;
Main3(int a) {
this.a=a;
}
@Override
public void run() {
super.run();
while (true) System.out.println(a);
}
public static void main(String[] args) {
Thread t=new Main3(1);
t.start();
Thread t1=new Main3(2);
t1.start();
}
}
