<---------------线程修改名字、得到名字及开启------------------>

ThreadDemo:
public class ThreadDemo extends Thread {
  public void run(){
      System.out.println(getName());//得到线程名字
    // System.out.println(0/0);
      for (int i = 0; i < 50; i++) {
        System.out.println("run里的。。。。"+i);
    }
  }
 
}

TestThreadDemo:
public class TestThreadDemo {
    public static void main(String[] args) {
        ThreadDemo th = new ThreadDemo();
        th.setName("旺财");//修改线程名字
        //th.run();
        th.start();//run开启线程
       　　fun1();
        //获得正在运行线程的名字
//        Thread cur = Thread.currentThread();
//        String name = cur.getName();
//        System.out.println(name);
        String name = Thread.currentThread().getName();
    }
    public static void fun1(){
        for (int j = 0; j <5000; j++) {
            System.out.println("main..."+j);
        }
        
    }
}
