Custom String representation of an Object in Java

Question

Is there any way to change how an Object represents itself as a String?

For example, having System.out.println(new JLabel()); output Empty JLabel.

Not on types you don't control.

You need to override the toString() method.

@Override
public String toString() {
    return "Empty JLabel";
}

Yes. Override the toString() method for that class

you could override the toString method like this:

public class A {

    @Override
    public String toString() {
        return "Empty A";
    }

    public static void main(String[] args) {
        System.out.println(new A());     // Empty A
    }
}
