Interfaces with same method names

Question

Hello!
A theoretical question:
There's a class, which implements 2 interfaces. Each interface has a method 'modszer'. Here's the code:
InterfaceA.java:
interface InterfaceA {
  void modszer();
InterfaceB.java:
interface InterfaceB {
  void modszer();
Osztaly.java:
public class Osztaly implements InterfaceA, InterfaceB {
  public void modszer() {
    System.out.println("So, which?");
FoOsztaly.java:
public class FoOsztaly {
  public static void main(String[] args) {
    Osztaly o = new Osztaly();
    o.modszer();
    InterfaceA ia = o;
    ia.modszer();
    InterfaceB ib = o;
    ib.modszer();
Sorry for the hungarian class names.
So how can I implement both 'modszer' methods, for example the method belongs to InterfaceA should return 'A' and the method if InterfaceB should return 'B'?
Thank you!

Only if they have different return types.There can be a problem with inheriting a method from
two different interfaces even if they have exactly the
same signature.
Consider the following interfaces and class:
interface Rectangle {
/** Display the rectangle on the screen */
void draw();
interface Card {
/** Remove the card from the deck */
void draw();
class GraphicCard implements Rectangle, Card {
/** What should this do!?!? */
public void draw();
}In this case, the draw() method in GraphicCard should
satisify two different contracts -- which one should
it satisfy? This is a real problem with multiple
inheritance of interface. It isn't as much of a
problem as multiple inheritance of implementation (as
in C++), but it still can be a problem when interface
methods have poorly chosen names.my solution to ur problem is
interface Rectangle{
void draw();
interface card {
void draw();
class Test implements Rectangle, Card
static String choice=null;
void Test(String str)
choice=string;
void draw()
if(choice.equals("Rectangle"))
//do
if(choice.equals("Card"))
//do
give this class to the user or application
if he wants to use rectangle or card
class User
Recatangle rec=(Rectangle)new Test("Rectangle");
rec.draw();
Card card=(Card) new Card("Card");
card.draw();
get back to me if iam wrong
