java Thread和Runnable区别

package com.tonyluis;
class MyThread extends Thread{
    private int ticketNum;
    private String name;
    public MyThread(String name,int ticketNum){
    	super("Thread:"+name);//线程名
        this.name =name;
        this.ticketNum=ticketNum;
    }
    public void run(){
    	int tmp=this.ticketNum;
    	String threadName = Thread.currentThread().getName();
        for(int i =0;i<tmp;i++){
            if(this.ticketNum>0){
                System.out.println("ThreadName:"+threadName+" "+this.name+"剩余 "+(this.ticketNum--));
            }
        }
    }
}
class MyThread1 implements Runnable{
    private int ticketNum =10;
    public void run(){
    	int tmp=this.ticketNum;
    	String threadName = Thread.currentThread().getName();
        for(int i =0;i<tmp;i++){
            if(this.ticketNum>0){
                System.out.println("ThreadName:"+threadName+" "+"剩余 "+(this.ticketNum--));
            }
        }
    }
}
public class TestThread {
    public static void main(String[] args) {
        new MyThread("窗口1",3).start();
        new MyThread("窗口2",4).start();
        new MyThread("窗口3",2).start();
        MyThread1 mt = new MyThread1();
        new Thread(mt,"窗口4").start();
        new Thread(mt,"窗口5").start();
        new Thread(mt,"窗口6").start();

    }  

}

运行结果：

ThreadName:Thread:窗口3 窗口3剩余 2
ThreadName:Thread:窗口1 窗口1剩余 3
ThreadName:Thread:窗口2 窗口2剩余 4
ThreadName:Thread:窗口1 窗口1剩余 2
ThreadName:Thread:窗口3 窗口3剩余 1
ThreadName:Thread:窗口1 窗口1剩余 1
ThreadName:Thread:窗口2 窗口2剩余 3
ThreadName:Thread:窗口2 窗口2剩余 2
ThreadName:Thread:窗口2 窗口2剩余 1
ThreadName:窗口5 剩余 10
ThreadName:窗口4 剩余 9
ThreadName:窗口6 剩余 10
ThreadName:窗口4 剩余 7
ThreadName:窗口5 剩余 8
ThreadName:窗口4 剩余 5
ThreadName:窗口6 剩余 6
ThreadName:窗口4 剩余 3
ThreadName:窗口5 剩余 4
ThreadName:窗口4 剩余 1
ThreadName:窗口6 剩余 2

继承Thread一般是多个线程分别完成自己的任务，实现Runable可以实现多个线程共同完成一个任务，而Thread需要通过内部类进行实现，实现起来比较麻烦

接口中不能有构造函数，所以，当你使用接口的时候，没法通过使用构造函数来传递变量。
