【Java多线程之线程命名 setname 构造器命名】

public class MyThread extends Thread {
    public MyThread() {

    }

    public MyThread(String name) {
        super(name);
    }

    public void run() {
        System.out.println(Thread.currentThread().getName());
    }
}

可以，创建带参数的thread 构造函数，将传参传递给父类去给线程命名；

import java.nio.file.SecureDirectoryStream;

public class Demo01Thread {
    public static void main(String[] arg) {
        MyThread mt = new MyThread();
        mt.setName("fang");
        mt.start();

        MyThread mt2 = new MyThread("fang2");
        mt2.start();
    }
}
