如何覆盖 Java 中的方法

Question

I play Robocode (it is a java programming game). I want to change the method

public void onScannedRobot (ScannedRobotEvent e) {

}

to

public int onScannedRobot(ScannedRobotEvent e){
}

So I can adapt my robot more if it scanned is true or false.

I heard that it is possible with Overriding a method. So I tryed it:

I wrote:

public void onScannedRobot(ScannedRobotEvent e) {

    public int onScannedRobot(ScannedRobotEvent e) {
        return 1;
    }
}

But it won't work

Answer 1

This won't work because the return type of overriden method should be the same or a subtype of the return type declared in the original method. Look at this link about overriding and this about overloading
