多线程兑现方法

两种实现方法：

继承Thread类，

实现Runnable接口

Thread类是Runnable接口的子类

使用Runnable接口可以实现资源共享的目的

所有的线程操作都必须通过Thread类的start()方法启动

package org.fool.thread;

public class ThreadTest
{
	public static void main(String[] args)
	{
		Thread thread1 = new Thread01();
		Thread thread2 = new Thread(new Thread02());
		
		thread1.start();
		thread2.start();

	}
}

class Thread01 extends Thread
{
	@Override
	public void run()
	{
		System.out.println(Thread.currentThread().getName());
	}
}

class Thread02 implements Runnable
{
	@Override
	public void run()
	{
		System.out.println(Thread.currentThread().getName());
	}
}
