java 线程演示

package unit8;

public class Mainthread {
    public static void main(String[] args) {
        Thread t  = new Thread().currentThread();
        System.out.println("当前的线程是："+t);
        t.setName("MyJavaThread");
        System.out.println("当前的线程是："+t);
        try{
            for(int i=0;i<3;i++){
                System.out.println(i);
                Thread.sleep(1500);
            }
        }catch(InterruptedException e){
            System.out.println("主线程被中断");
        }
        System.out.println("主线程结束");
    }
}

当前的线程是：Thread[main,5,main]
当前的线程是：Thread[MyJavaThread,5,main]

主线程结束
