Answer 1

Check this link for the answer.



It is the method name and the number of and type of parameters that make up the method signature, not the return type.



So surely if you have a method with a different return type then it is a totally different method and the name should therefore be different.



Have fun.

Answer 2

You can change the return type because it does not matter

but you can not change order of parameters because then your method becomes an overloaded version of superclass method

Answer 3

while over-riding a method, signatures of method must exactly match.

That means you cant change its return type or name or parameter list. However you can change the method body.
