Thread 和 Runnable 的一些区别

package com.lsh.java8.thread;

import java.util.concurrent.atomic.AtomicInteger;

public class MySimpleRunnable implements Runnable
{
private static AtomicInteger index = new AtomicInteger();

private AtomicInteger value = new AtomicInteger(10);

@Override
public void run() {
for(int i = 0 ; i < 10 && value.get() >= 0; i++)
{
System.out.println(Thread.currentThread().getName() + ": value = " + value.getAndDecrement());
}
}

public static void main(String[] args)
{
Thread thread = new Thread(new MySimpleRunnable());
new Thread(thread, "My_runnable" + index.getAndIncrement()).start();
new Thread(thread, "My_runnable" + index.getAndIncrement()).start();
new Thread(thread, "My_runnable" + index.getAndIncrement()).start();
}
}
