一、讓目標類繼承Thread類

package com.atzhongruan.springboot_boostrap.Test;

/**
 * @Author jose

 */
public class Task1 extends Thread{
    @Override
    public void run() {
        for (int j = 0; j < 100000; j++) {
            System.out.println("i============================="+j);
        }

    }
}

package com.atzhongruan.springboot_boostrap.Test;

/**
 * @Author jose
 * date 2019
 */
public class Task2 extends Thread {

    @Override
    public void run() {
        for (int i = 0; i < 1000000; i++) {
            System.out.println("i="+i);
        }
    }
}

package com.atzhongruan.springboot_boostrap.Test;

/**
 * @Author jose
 * date 2019
 */
public class Window {
    public static void main(String[] args) {
        //建立執行緒1
        Task1 task1 = new Task1();
        //建立執行緒2
        Task2 task2 = new Task2();
        //執行程式
        task1.start();
        task2.s
