韩顺平 java 第39讲 线程

多个线程

package com.chen;

public class MyClass {
    public static void main(String[] args) {
        Cat cat = new Cat();
        Dog dog = new Dog();
        //创建一个Thread对象
        Thread t1 = new Thread(cat);
        Thread t2 = new Thread(dog);
        t1.start();
        t2.start();
    }
}
class Cat implements Runnable{
    public void run(){
        int i = 0;
        while(i < 10){
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            System.out.println("Cat:" + i);
            ++i;
        }
    }
}
class Dog implements Runnable{
    public void run(){
        int j = 0;
        while(j < 10){
            try {
                Thread.sleep(700);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            System.out.println("Dog:" + j);
            ++j;
        }
    }
}

所以我们尽可能的使用实现Runnable接口的方式来创建线程。
