class Generic<G> {
	void take(G g) {
		System.out.println("Generic#take(G): " + g);
	}
}

class Impl extends Generic<Number> {
	void take(Integer g) {
		System.out.println("nonripple Impl#take(Integer): " + g);
	}
	void take(Number g) {
		System.out.println("Impl#take(Number): " + g);
	}
}

Search for declarations of Generic#take(G). Both methods in Impl are reported,
but Impl#take(Integer) does not override Generic#take(G).

Here's a test program you can use to play with method overriding:

public class Main {
    public static void main(String[] args) {
        new Generic<Number>().take(new Double(1));
        new Generic<Integer>().take(new Integer(2));

        new Impl().take(new Integer(3));
        new Impl().take(new Float(4));
        
        Generic<Number> gn= new Impl();
        gn.take(new Integer(6));
        gn.take(new Double(7));
    }
}
