Java 线程启动（实现Runnable接口）

程序如下：

class ThreadDemo1 implements Runnable{//实现Runnable接口
	private String name;
	private int time;
	public ThreadDemo1(String name,int time){
		this.name=name;
		this.time=time;

	}

	public void run() {//覆写run方法
		try {
			Thread.sleep(this.time);
		} catch (InterruptedException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		System.out.println(this.name+"线程休眠"+this.time);

	}

}
public class MyThread {

	public static void main(String[] args) {
		ThreadDemo1 thread01=new ThreadDemo1("A",1000);//实现Runnable 子类对象；
		ThreadDemo1 thread02=new ThreadDemo1("B",2000);
		ThreadDemo1 thread03=new ThreadDemo1("C",3000);
		new Thread(thread01).start();//实例化Thread类，启动线程
		new Thread(thread02).start();
		new Thread(thread03).start();

	}

}

运行如下：

A线程休眠1000

B线程休眠2000

C线程休眠3000
