  • Java SE (5)之 线程使用

    JAVA有两种线程的方法Thread 和Runnable 能够使用,这是为了弥补不能多继承的缺陷

    首先是 Thread

    package com.sunzhiyan03;
    /*
     * 演示线程
     * */
    public class Demo1 {
    
    	public Demo1() {
    		// TODO Auto-generated constructor stub
    	}
    
    	public static void main(String[] args) {
    		// TODO Auto-generated method stub
    		Cat cat1 = new Cat();
    		//启动线程,导致run函数的调用
    		cat1.start();
    	}
    
    }
    //继承线程
    class Cat extends Thread{
    	//重写run 函数
    	int times = 0;
    	public void run(){
    		while(true){
    			//休眠一秒
    			//blocked状态,释放资源
    			try {
    				Thread.sleep(1000);
    			} catch (InterruptedException e) {
    				// TODO Auto-generated catch block
    				e.printStackTrace();
    			}
    			times ++;
    			System.out.println("hello , world");
    			//跳出循环
    			if(times == 10){
    				break;
    			}
    		}		
    	}
    	
    }
    

      然后是Runnable

    package com.sunzhiyan03;
    
    public class Demo2 {
    
    	public Demo2() {
    		// TODO Auto-generated constructor stub
    	}
    
    	public static void main(String[] args) {
    		// TODO Auto-generated method stub
    		Dog dog = new Dog();
    		//dog.run();
    		//借助Thread 的start方法进行启动
    		Thread t = new Thread(dog);
    		t.start();
    	}
    
    }
    class Dog implements Runnable{
    	int times = 0;
    	public void run(){
    		while(true){
    			try {
    				Thread.sleep(1000);
    			} catch (InterruptedException e) {
    				// TODO Auto-generated catch block
    				e.printStackTrace();
    			}
    			System.out.println("hello,world"+times);
    			times ++;
    			if(times == 10){
    				break;
    			}
    		}
    	}
    	
    }
