冗余的Runnable代码

public class Demo01Runnable {
    public static void main(String[] args) {
        //创建runnable接口的实现对象
        RunnableImpl run=new RunnableImpl();
        //创建Thread对象，构造方法中传递Runnable接口实现类
        Thread t=new Thread(run);
        //调用start方法开启新线程，执行run方法
        t.start();

        Runnable r=new Runnable(){

            @Override
            public void run() {
                System.out.println(Thread.currentThread().getName()+"新线程创建了");
            }
        };

        new Thread(r).start();

        //简化代码
        new Thread(new Runnable(){

            @Override
            public void run() {
                System.out.println(Thread.currentThread().getName()+"新线程创建了");
            }
        }).start();
    }
}
