调用线程对象的start()方法启动线程


public  class TestThread1 {

 public static void main(String args[]) {

  Runner1 r = new Runner1();

  Thread t = new Thread(r);

  t.start();//线程启动

  

  for(int i=0; i<100; i++) {

   System.out.println("Main Thread:------" + i);

  }

 }

}

class Runner1 implements Runnable {

//class Runner1 extends Thread {//能实现接口就不用Thread类继承

 public void run() {

  for(int i=0; i<100; i++) { 

   System.out.println("Runner1 :" + i);

  }

 }

}

运行结果：

Main Thread:------0

Runner1 :0

Runner1 :1

Runner1 :2

Main Thread:------1

Main Thread:------2

Main Thread:------3

...

Main Thread:------94

Main Thread:------95

public  class TestThread1 {

 public static void main(String args[]) {

  Runner1 r = new Runner1();

  r.run();//方法调用

  

  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);

  }

 }

}
