Java多线程Thread，Runable

实现Runable

public class MyRunable implements Runnable {

    String str;

    public MyRunable(String str) {
        this.str = str;
    }

    @Override
    public void run() {
        for(int i = 1; i <= 10; i++) {
            System.out.println(str+"   "+i);
        }
    }
}

继承Thread

public class MyThread extends Thread{

    String str;

    public MyThread(String str) {
        this.str = str;
    }

    @Override
    public void run() {
        for(int i = 1; i <= 10; i++) {
            System.out.println(str+"   "+i);
        }
    }
}

测试代码

import org.junit.jupiter.api.Test;

public class ThreadTest {

    /**
     * 继承Thread实现多线程
     */
    @Test
    public void testThread(){
        MyThread myThread1=new MyThread("myThread1");
        MyThread myThread2=new MyThread("myThread2");
        myThread1.start();
        myThread2.start();
    }

    /**
     * 实现Runable接口实现多线程
     */
    @Test
    public void testRunable(){
        MyRunable myRunable1=new MyRunable("myRunable1");
        MyRunable myRunable2=new MyRunable("myRunable2");
        Thread thread1=new Thread(myRunable1);
        Thread thread2=new Thread(myRunable2);
        thread1.start();
        thread2.start();
    }
