java使用匿名内部类实现多线程

public class demo {
    public static void main(String[] args) {
        //方法一
        new Thread(){
            @Override
            public void run() {
                for (int i = 0; i < 20; i++) {
                    System.out.println(Thread.currentThread().getName()+i);
                }
            }
        }.start();
        //方法二
        new Thread(new Runnable() {
            @Override
            public void run() {
                for (int i = 0; i < 20; i++) {
                    System.out.println(Thread.currentThread().getName()+i);
                }
            }
        },"Runnable").start();
    }
}
