【二】Java多线程创建方法

1.实现Runable接口

public class MyThread implements Runnable{
    int count;
    String thrdName;

    MyThread(String name){
        count = 0;
        thrdName = name;
    }
    public void run() {
        System.out.println(thrdName+" starting.");
        try {
            do {
                Thread.sleep(500);
                System.out.println("In "+thrdName+",count is "+count);
                count++;
            }while (count<10);
        }catch (Exception e){
            System.out.println(thrdName+" interrupted.");
        }

        System.out.println(thrdName+" terminating.");

    }

    public static void main(String[] args) {
        System.out.println("Main Thread starting.");
        MyThread mt = new MyThread("Child #1");
        //创建一个Thread对象
        Thread t1 = new Thread(mt);
        //开始运行线程
        t1.start();

    }
}

2.继承Thread类

public class MyThread2 extends Thread{
    int count;
    String thrdName;

    MyThread2(String name){
        count = 0;
        thrdName = name;
    }
    @Override
    public void run() {
        System.out.println(thrdName+" starting.");
        try {
            do {
                Thread.sleep(500);
                System.out.println("In "+thrdName+",count is "+count);
                count++;
            }while (count<10);
        }catch (Exception e){
            System.out.println(thrdName+" interrupted.");
        }

        System.out.println(thrdName+" terminating.");

    }

    public static void main(String[] args) {
        System.out.println("Main Thread starting.");
        //创建一个Thread对象
        Thread t2 = new MyThread2("Child #2");
        //开始运行线程
        t2.start();

    }
}
