java - How to start anonymous thread class

Question

I have the following code snippet:

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

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

Answer 1

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();

... 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();
