It is called method overloading and is when you have 2 or more methods in the same class with the same name but taking different number and or types of arguments

As of 1.5 you can override a method with one that has a return type which is a subclass of the parent class method

 
class A {
 public Number a() {
  return 1;
 }
}
class B extends A {
 public Integer a() {
  return 1;
 }
}

Compiles fine in 1.5 but not on 1.4 compilers
