Java多线程-实现Runnable接口run方法，示例

  实现Runnable接口，并通过Thread类的构造器，创建线程。

  示例如下

public class ThreadTest implements Runnable{
    @Override
    public void run() {
        for (int i = 0; i<5 ; i++){
            System.out.println("Thread-"+Thread.currentThread().getName()+": "+i);
            try {
                Thread.sleep(Math.round(Math.random()*1000)); // 随机线程休眠时长
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }

    }
    public static void main(String[] args){
        new Thread(new ThreadTest(),"Thread-1").start();  // 通过Thread的构造器创建线程，并调用start方法启动线程
        new Thread(new ThreadTest(),"Thread-2").start();
    }

}

执行结果如下

Thread-Thread-1: 0
Thread-Thread-2: 0
Thread-Thread-2: 1
Thread-Thread-1: 1
Thread-Thread-2: 2
Thread-Thread-2: 3
Thread-Thread-1: 2
Thread-Thread-1: 3
Thread-Thread-1: 4
Thread-Thread-2: 4
