Java多线程(一) Thread和 Runnable
http://www.cnblogs.com/lwbqqyumidi/p/3804883.html
1.继承Thread
2.实现Runnable接口
public class MyRunnable implements Runnable { @Override public void run() { // TODO Auto-generated method stub System.out.println("running.."); } }
public class Run { public static void main(String[] args) { Runnable runnable =new MyRunnable(); Thread thread = new Thread(runnable); thread.start(); } }
如果同时继承Thread类实现Runnable接口,实际执行的Thread的run方法
public class ThreadTest { public static void main(String[] args) { for (int i = 0; i < 100; i++) { System.out.println(Thread.currentThread().getName() + " " + i); if (i == 30) { Runnable myRunnable = new MyRunnable(); Thread thread = new MyThread(myRunnable); thread.start(); } } } } class MyRunnable implements Runnable { private int i = 0; @Override public void run() { System.out.println("in MyRunnable run"); for (i = 0; i < 100; i++) { System.out.println(Thread.currentThread().getName() + " " + i); } } } class MyThread extends Thread { private int i = 0; public MyThread(Runnable runnable){ super(runnable); } @Override public void run() { System.out.println("in MyThread run"); for (i = 0; i < 100; i++) { System.out.println(Thread.currentThread().getName() + " " + i); } } }
