如何启动匿名线程类 [英] How to start anonymous thread class

问题描述

我有以下代码段:

public class A {
    public static void main(String[] arg) {
        new Thread() {
            public void run() {
                System.out.println("blah");
            }
        };
    }
}

在这里，如何在不创建线程类实例的情况下为线程调用start()方法?

Here, how do I call the start() method for the thread without creating an instance of the thread class?

推荐答案

您已经在创建Thread类的实例-您只是对它不做任何事情.您甚至可以不使用局部变量来调用start():

You're already creating an instance of the Thread class - you're just not doing anything with it. You could call start() without even using a local variable:

new Thread()
{
    public void run() {
        System.out.println("blah");
    }
}.start();

...但是我个人通常会将其分配给局部变量，然后执行您要执行的其他任何操作(例如，设置名称等)，然后启动它:

... but personally I'd normally assign it to a local variable, do anything else you want (e.g. setting the name etc) and then start it:

Thread t = new Thread() {
    public void run() {
        System.out.println("blah");
    }
};
t.start();
