Java多线程-Thread&Runnable的关系

Posted 2022-05-01 starstarstar

Thread创建多线程：

MyThread.class
package com.test.interview;

public class MyThread extends Thread 
    private String name;

    public MyThread(String name) 
        this.name = name;
    

    @Override
    public void run() 
        for (int i = 0; i < 10; i++) 
            System.out.println("thread start:" + this.name + ",i=" + i);
        
    

ThreadDemo.class
package com.test.interview;

public class ThreadDemo 
    public static void main(String[] args) 
        MyThread mt = new MyThread("thread1");
        MyThread mt2 = new MyThread("thread2");
        MyThread mt3 = new MyThread("thread3");
        mt.start();
        mt2.start();
        mt3.start();
    

Runnable创建多线程：

RunnableDemo.class
package com.test.interview;

public class RunnableDemo 
    public static void main(String[] args) 
        MyRunnable mr1 = new MyRunnable("Runnable1");
        MyRunnable mr2 = new MyRunnable("Runnable2");
        MyRunnable mr3 = new MyRunnable("Runnable3");
        Thread t1 = new Thread(mr1);
        Thread t2 = new Thread(mr2);
        Thread t3 = new Thread(mr3);
        t1.start();
        t2.start();
        t3.start();
    

MyRunnable.class
package com.test.interview;

public class MyRunnable implements Runnable 
    private String name;

    public MyRunnable(String name) 
        this.name = name;
    
    @Override
    public void run() 
        for (int i = 0; i < 10; i++) 
            System.out.println("thread start:" + this.name + ",i=" + i);
