JAVA多线程实现的两种方式

一.直接上代码

方式一：

package com.zhc.threaddemo;

public class MyThread extends Thread {//方式一：继承Thread类。

public void run() {
System.out.println("extends Thread:"+"MyThread.run()");
}
}


方式二：
package com.zhc.threaddemo;

public class YouThread implements Runnable {//方式二：实现Runnable接口。

@Override
public void run() {
System.out.println("implements Runnable"+"YouThread.run()");
}

}


两种方式在对应合适的地方启动线程
package com.zhc.threaddemo;

import android.os.Bundle;
import android.app.Activity;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

//方式一：继承Thread类。
MyThread myThread1 = new MyThread();
MyThread myThread2 = new MyThread();
myThread1.start();
myThread2.start();

//方式二：实现Runnable接口。
YouThread youThread = new YouThread();
Thread thread = new Thread(youThread);
thread.start();
}
}
