Java多线程

Java多线程的线程类需继承于Thread类，并且需要重写run函数。

sleep休眠时使用Thread.sleep( 200 )这种形式，并且要放在try-catch语句块中。

 下面给出简单demo：

class MyThread extends Thread{
    public void run(){
        for( int i=0; i<10; ++i ){
            System.out.println( "Thread name is: " + this.getName() );
            try{
                Thread.sleep(300);    
            }
            catch( InterruptedException e ){
                System.out.println( e.getMessage() );
            }
        }
    }
}

public class TestMultiThread{
    public static void main(String[] args){
        MyThread thread1 = new MyThread( "ThreadA" );
        MyThread thread2 = new MyThread( "ThreadB" );
        //MyThread thread3 = new MyThread( "ThreadC" );
        
        thread1.start();
        thread2.start();
        //thread3.start();    
    }
}
