runnable.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.Runnable;
import java.lang.Thread;
import java.lang.Math;

class myRunnable implements Runnable{
	myRunnable(String str){
		Thread t=new Thread(this,str);
		t.start();
		}
	public void run(){
		int i;
		for(i=1;i<=5;i++)
		{
			System.out.println("RunnableThread:"+i);
			try{
				Thread.sleep((int)(Math.random()*1000));				
			}
			catch(InterruptedException e){
			}
		}
	}
}

class mainThread{
	public static void main(String args[])
	{
		new myRunnable("myRunnable");
		int i;
		for(i=1;i<=5;i++)
		{System.out.println("mainThread:"+i);
		try{
			Thread.sleep((int)(Math.random()*1000));			
		}
		catch(InterruptedException e){
		}
		}
	}
	
	
}
