本文实例讲述了Java使用Thread创建多线程并启动操作。分享给大家供大家参考，具体如下：

按照教程实现了一个单线程的创建，但是单线程的创建于启动并不是很有实用价值的。毕竟直接在main方法中放着相关的执行操作本身也就是一种单线程的实现。接下来在之前用过的代码基础上稍作修改，形成如下代码：


class ThreadDemo extends Thread
{
    ThreadDemo(){};
    ThreadDemo(String szName)
    {
       super(szName);
    }
    public void run()
    {
       int i = 0;
       for(i = 0;i < 10;i++)
       {
           System.out.println("run" + (i + 1) + " times");
       }
    }
    public static void main(String[] args)
    {
       ThreadDemo demo1 = new ThreadDemo();
       ThreadDemo demo2 = new ThreadDemo();
       ThreadDemo demo3 = new ThreadDemo();
       demo1.start();
       demo2.start();
       demo3.start();
    }
}

代码编译运行结果如下;
