public class House {
  public int numberOfBedrooms = 3;

  public int getNumberOfBedrooms() {
    return numberOfBedrooms;
  } 

  // Overloading getNumberOfBedrooms() with the following method
  // will NOT work. The compiler will complain about the method
  // already being defined:
  public String getNumberOfBedrooms() {
    return Integer.toString(numberOfBedrooms);
  } 

  // Overloading getNumberOfBedrooms() with the following method
  // will work. It differs in return type and arguments
  public String getNumberOfBedrooms(String s) {
    return Integer.toString(numberOfBedrooms) + s;
  } 
}
