public class TestThread1 {
        public static void main(String[] args) {
            Thread thread = new Thread(){
                @Override
                public void run () {
                    while (true) {
                        try {
                            Thread.sleep(500);//让它休息0.5秒
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                        System.out.println(Thread.currentThread().getName() + "----------------");
                    }
                }
            };
            thread.start();
            Thread thread1 = new Thread(new Runnable() {
                @Override
                public void run() {
                    while (true) {
                        try {
                            Thread.sleep(500);
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                        System.out.println(Thread.currentThread().getName() + "----------------");
                    }
                }
            });
            thread1.start();
            new Thread(new Runnable() {
                @Override
                public void run() {
                    while (true) {
                        try {
                            Thread.sleep(500);
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                        System.out.println("4"+Thread.currentThread().getName() + "----------------");
                    }
                }
            }){
                @Override
                public void run() {
                    while (true) {
                        try {
                            Thread.sleep(500);
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                        System.out.println("3"+Thread.currentThread().getName() + "----------------");
                    }
                }
            }.start();
        }
    }

虽然创建多线程的方式有两种但是我们一般常用

Thread thread1 = new Thread(new Runnable() {
        @Override
        public void run() {
            while (true) {
                try {
                    Thread.sleep(500);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                System.out.println(Thread.currentThread().getName() + "----------------");
            }
        }
    });
    thread1.start();
    
    因为这种方式更能体现面向对象的方式，把线程的创建和代码部分分开了,还有一点必须要纠正的是，并不是说多线程一定会使项目快很多，还是那句话，没有优秀的技术，只有适合的技术与不适合的技术。
