java多线程的实现的两种方法-优快云博客

本文介绍了Java中实现多线程的两种主要方法：通过继承Thread类和实现Runnable接口。通过具体的代码示例展示了如何创建和启动多线程，并在主线程中并发执行多个子线程。

通过继承Thread类实现多线程-

public class Hello{
    public static void main(String args[]){
        MyThread tr1 = new MyThread("线程1");
        MyThread tr2 = new MyThread("线程2");
        MyThread tr3 = new MyThread("线程3");
        tr1.start();
        tr2.start();
        tr3.start();
    }
}
class MyThread extends Thread{
    private String name;
    public MyThread(String name){
        this.name = name;
    }
    @Override
    public void run() {
        for(int x=0; x<10; x++){
            System.out.println(this.name+",x="+x);
        }
    }
}

通过Runnable接口实现多线程

public class Hello{
    public static void main(String args[]){

        MyThread mt1 = new MyThread("线程A");
        MyThread mt2 = new MyThread("线程B");
        MyThread mt3 = new MyThread("线程C");
        Thread tr1 = new Thread(mt1);
        Thread tr2 = new Thread(mt2);
        Thread tr3 = new Thread(mt3);
        tr1.start();
        tr2.start();
        tr3.start();

    }
}
class MyThread extends Thread{
    private String name;
    public MyThread(String name){
        this.name = name;
    }
    @Override
    public void run() {
        for(int x=0; x<10; x++){
            System.out.println(this.name+",x="+x);
        }
    }
}
