多线程 Runnable 实现线程 内部类

public class ThreadDemo4 {
    public static void main(String[] args){
        System.out.println(Thread.currentThread().getName());//main
        Thread.currentThread().setName("haha");
        String name = Thread.currentThread().getName(); // haha
        Thread t = Thread.currentThread();
        System.out.println(t.getPriority());// 5   线程默认优先级是 5
        t.setPriority(10); // 设置优先级 1 - 10
        System.out.println(t.getPriority());
        System.out.println(name);


        MyRunable m1 = new MyRunable();
        Thread t1 = new Thread(m1);
        t1.start();
        System.out.println(t1.getName()); //Thread-0




        // 匿名内部类对象实现
        new Thread(
                new Runnable(){
                    public void run(){
                        System.out.println(Thread.currentThread().getName());//Thread-1
                        System.out.println("我是匿名内部类");
                    }
                }
        ).start();
        

        //匿名类
        new Thread(){
            public void run(){
                System.out.println(Thread.currentThread().getName());//Thread-2
                System.out.println("匿名类"); 
            }
        }.start();


    }
}



//Runable 接口 实现线程

class MyRunable implements Runnable{
    public void run(){
       System.out.println("helloworld");
    }
}
