thread.java

java学习的作业 1.runnable和thread的使用区别 2.interf和commo的使用 3.用java实现画图程序

import java.lang.Thread;
class mythread extends Thread{
	mythread(String str){
		super(str);
		this.start();
		
	}
	public  void run(){
		int i;
		for(i=1;i<=5;i++)
		{
			System.out.println("subThread:"+i);
			try{
				sleep(100);
			}
			catch(InterruptedException e){
			}
		}
	}
}

class mainthread extends Thread{
	public static void main(String args[])
	{
		new mythread("subthread");
		int i;
		for(i=1;i<=5;i++)
		{
			System.out.println("mainthread:"+i);
			try{
				sleep(100);
			}
			catch(InterruptedException e){
			}
		}
	}
	
}
