关于多线程的创建

import com.sun.deploy.ref.Helpers;

public class DuoXianCeng {
    public static void main(String[] args) {
        System.out.println("The main method was sdf:"+Thread.currentThread().getName());
        Helper helper = new Helper("Java Thread Anywhere");


        //创建一个线程
        Thread thread = new Thread(helper);
        //设置线程名字
        thread.setName("A-Worker-Thread");
        //启动线程
        thread.start();
    }

    static class Helper implements Runnable {
     private final  String message;

        public Helper(String message) {
            this.message = message;
        }

        private void doSomething(String message) {
            System.out.println("The doSomething method ws executed by thread:" + Thread.currentThread().getName());
            System.out.println("Do something with" + message);
        }

        @Override
        public void run() {
            doSomething(message);
        }

    }
}

这是创建多线的流程的流程

* Thread用法

1、先继承Thread类，重写run()方法，将要运行的代码写到run()方法里；

2、实例化线程类，调用start()方法，开始线程；

3、start()方法被调用，执行的是线程类中重写后的run()方法内的代码

* Runnable用法

Thread t = new Thread(new RunnableDemo,"ThreadName");

t.start();
