该方法可返回代码段正在被哪个线程调用的信息
1 package com.cky.test; 2 3 /** 4 * Created by chenkaiyang on 2017/12/2. 5 */ 6 public class Test { 7 public static void main(String[] args){ 8 9 System.out.println(Thread.currentThread().getName()); 10 } 11 }

main
Process finished with exit code 0
结果分析：main方法被名为main的线程调用
测试下面

构造方法的打印：main
run方法的打印main
Process finished with exit code 0
结果分析：MyFirstThread类的构造函数是被main线程调用的，而run方法是被名为Thread-0的线程调用的，run方法是自动调用的方法。
下面测试一个比较复杂的情况
