Java 线程

//方式1：继承Thread类
//播放音乐线程类
class MusicThread extends Thread{
	public void run() {
		for (int i = 0; i <50; i++) {
			System.out.println("我在听音乐！"+i);
		}
	}
}
public class Thread_create {

	public static void main(String[] args) {
		for (int i = 0; i < 50; i++) {
			System.out.println("我在打游戏"+i);
			if(i==10){
				//创建线程并启动对象
				MusicThread music=new MusicThread();
//				music.run();
				music.start();//不能调用run方法
			}
		}

	}

}

//实现Runnable接口
//播放音乐的类
class RunnableMusic implements Runnable{
	public void run() {
		for (int i = 0; i <50; i++) {
			System.out.println("我在听音乐！"+i);
		}
	}
	
}
public class ImplementsRunnable {
	public static void main(String[] args) {
		//运行游戏
				for (int i = 0; i < 50; i++) {
					System.out.println("我在打游戏"+i);
					if(i==10){
						//创建线程并启动对象
						Runnable r=new RunnableMusic();
					Thread runnable=	new Thread(r);
					runnable.start();
					}
				}
	}
