See overloading has nothing to do with Covariant Return
types ,in fact overloading dosent take into consideration
the return types.
But in case of ovveriding u can provide Covariant return type
say for example
class A {
protected A getModel(){
return this;
}
}
class B extends A{
public B getModel(){
return this
}
}
and there are many other examples of
covariant return types like this.
Since B is A(IS-A RelationShip)
so the return type can be a subclas of the super class
