多线程进一步的理解------------线程的创建

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。
