     * 启动一个线程的3种方式
     */
    public class TraditionalThread {
    
    	public static void main(String[] args) {
    		// 1. 继承自Thread类（这里使用的是匿名类）
    		new Thread(){
    			@Override
    			public void run() {
    				while(true) {
    					try {
    						Thread.sleep(500);
    					} catch (InterruptedException e) {
    						e.printStackTrace();
    					}
    					System.out.println("threadName: " + Thread.currentThread().getName());
    				}
    			};
    		}.start();
    		
    		// 2. 实现Runnable接口（这里使用的是匿名类）
    		new Thread(new Runnable() {
    			@Override
    			public void run() {
    				while(true) {
    					try {
    						Thread.sleep(500);
    					} catch (InterruptedException e) {
    						e.printStackTrace();
    					}
    					System.out.println("threadName: " + Thread.currentThread().getName());
    				}
    			}
    		}).start();
    		
    		// 3.即实现Runnable接口，也继承Thread类，并重写run方法
    		new Thread(new Runnable() {
    			@Override
    			public void run() {	// 实现Runnable接口
    				while(true) {
    					try {
    						Thread.sleep(500);
    					} catch (InterruptedException e) {
    						e.printStackTrace();
    					}
    					System.out.println("implements Runnable thread: " + Thread.currentThread().getName());
    				}
    			}
    		}) {	// 继承Thread类
    			@Override
    			public void run() {
    				while(true) {
    					try {
    						Thread.sleep(500);
    					} catch (InterruptedException e) {
    						e.printStackTrace();
    					}
    					System.out.println("extends Thread thread: " + Thread.currentThread().getName());
    				}
    			}
    		}.start();
    	}
    }

**执行结果：**

threadName: Thread-0

threadName: Thread-1

extends Thread thread: Thread-2

threadName: Thread-1

threadName: Thread-0

extends Thread thread: Thread-2

threadName: Thread-1

threadName: Thread-0

extends Thread thread: Thread-2
