Thread和Runnable 的使用

Thread:

public class TestThread {

 public static void main(String[] args) {
  MyThread thread1 = new MyThread();
  MyThread thread2 = new MyThread();
  thread1.start();
  thread2.start();
 }

}

public class MyThread extends Thread{

 @Override
 public void run() {
  System.out.println(this.getName()+"线程被执行");
  try {
   Thread.sleep(1000);
  } catch (InterruptedException e) {
  }
  System.out.println(this.getName()+"线程关闭了");
 }
 
}

Runnable接口:

public class TestThread2 implements Runnable{
 public void run() {
  System.out.println("线程启动");
  try {
   Thread.sleep(2000);
  } catch (InterruptedException e) {
  }
  System.out.println("线程结束");
 }
 
 public static void main(String[] args){
  TestThread2 t = new TestThread2();
  Thread t1 = new Thread(t);
  Thread t2 = new Thread(t);
  t1.start();
  t2.start();
 }
}
