There are 2 methods in a class. Both have the same method
signature except for return types. Is this overloading or
overriding or what is it?

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
