Simple Inheritance using Java

abstract class GameObject {
    public abstract void touch(GameObject other);
    // NOTE: This is ugly because these two definitions need to be in the main
    //       class, it could be avoided by some more functionality i think?
    public abstract void touch(Mazub other);
    public abstract void touch(Plant other);
}

class Mazub extends GameObject {
    @Override
    public void touch(GameObject other) {
        other.touch(this);
    }
    
    @Override
    public void touch(Plant plant) {
        System.out.println("Mazub touches Plant");
    }
    
    @Override
    public void touch(Mazub mazub) {
        System.out.println("Mazub touches Mazub");
    }
}

class Plant extends GameObject {
    @Override
    public void touch(GameObject other) {
        other.touch(this);
    }
    
    @Override
    public void touch(Mazub mazub) {
