编写线程类:继承Thread 类

package com.one.thread;

/**
 * 线程类, 使用Thread
 * @author Administrator
 *
 */
public class MyThread extends Thread {

	public MyThread() {
	}
	
	public MyThread(String name) {
		super(name);
	}

	@Override 
	public void run(){
		
		for (int i = 1; i <= 100; i++) {
			//输出当前线程名 和 数值i
			System.out.println(Thread.currentThread().getName() + ": " + i);
		}
	}
}

package com.one.thread;

/**
 * 测试类, 线程类的使用
 * @author Administrator
 *
 */
public class Test1 {

	public static void main(String[] args) {
		
		//创建线程对象
//		MyThread t1 = new MyThread();
//		MyThread t2 = new MyThread();
		
		MyThread t1 = new MyThread("张三");
		MyThread t2 = new MyThread("李四");
				
		//设置线程名称
//		t1.setName("A");
//		t2.setName("B");
		
		//启动线程,调用start方法
		t1.start();
		t2.start();
		//启动线程,调用run方法
//		t1.run();
//		t2.run();
	}
}
