传统线程技术

创建并启动一个线程

方法一

public static void main(String[] args) {
    Thread thd01 = new Thread("thd01") {
        @Override
        public void run() {
            System.out.println("the Thread " + Thread.currentThread().getName() + " is executing.");
        }
    };
    thd01.start();
    System.out.println("the Thread " + Thread.currentThread().getName() + " is executing.");
}

方法二

public static void main(String[] args) {
    Thread thd02 = new Thread(new Runnable() {
        @Override
        public void run() {
            System.out.println("the Thread " + Thread.currentThread().getName() + " is executing.");
        }
    });
    thd02.setName("thd02");
    thd02.start();
    System.out.println("the Thread " + Thread.currentThread().getName() + " is executing.");
}

判断输出结果

public static void main(String[] args) {
    new Thread(new Runnable() {
        public void run() {
            System.out.println("the Thread01 " + Thread.currentThread().getName() + " is executing.");
        }
    }) {
        /** 覆盖了Runnable中定义的方run() */
        @Override
        public void run() {
            System.out.println("the Thread02 " + Thread.currentThread().getName() + " is executing.");
        }
    }.start();
}
