public class TestThread1{
	public static void main(String args[]){
		Runner1 r=new Runner1();　　　　　　　　　　r.run();
		//Thread t=new Thread(r);//方法1
	  	//t.start();//方法1

		for (int i =0;i<100;i++){
			System.out.println("Main Thread:---------" + i);

		}
	}
}

class Runner1 implements Runnable{
	public void run(){
		for (int i =0;i<100;i++){
			System.out.println("Runner1:" + i );
		}
	}
}

Start:Runner1和Main Thread交替运行。

run:Runner1先运行，Main Thread后运行
