java多线程

1.继承Thread类

public class MyThread extends Thread {
    @Override
    public void run() {
        super.run();
        System.out.println("MyThread");
    }
}

public class Run {

    public static void main(String[] args) {
        MyThread mythread = new MyThread();
        mythread.start();
        System.out.println("运行结束");
    }

}

2.实现Runnable接口

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

public class Run {

    public static void main(String[] args) {
        Runnable runnable=new MyRunnable();
        Thread thread=new Thread(runnable);
        thread.start();
        System.out.println("运行结束！");
    }

}
