多线程1------------创建线程的两种方法

package ThreadTest;

public class TraditionalThread01 {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
//		Thread thread = new Thread(){};//这种写法是Thread的子类
		Thread thread = new Thread(){
			@Override
			public void run() {
				while(true){
					try {
						Thread.sleep(500);
					} catch (InterruptedException e) {
						// TODO Auto-generated catch block
						e.printStackTrace();
					}
					System.out.println("1"+Thread.currentThread().getName());//Thread.currentThread()表示当前线程
					System.out.println("2"+this.getName());//this 代表run方法所在的对象

				}
			}

		};
		thread.start();
//		System.out.println(Thread.currentThread().getName());//main
	}

}

注意下this表示执行run方法的对象，并不一定是线程，也可能是runnable对象

package ThreadTest;

public class TraditionalThread2 {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        // Thread thread1 = new Thread(){};//这种写法是Thread的子类
        Thread thread1 = new Thread() {// 这种方式覆盖父类的run方法
            @Override
            public void run() {
                while (true) {
                    try {
                        Thread.sleep(500);
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    System.out.println("1" + Thread.currentThread().getName());// Thread.currentThread()表示当前线程
//                    System.out.println("2" + this.getName());// this 代表run方法所在的对象

                }
            }

        };
        thread1.start();

        Thread thread2 = new Thread(new Runnable() {

            @Override
            public void run() {
                try {
                    Thread.sleep(500);
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                System.out.println("11" + Thread.currentThread().getName());// Thread.currentThread()表示当前线程

                // this 代表run方法所在的对象,是runnable对象，他不是线程没有getName方
                // System.out.println("222"+this.getName());

            }
        });

        thread2.start();
    }
