    When a method in a subclass has the same name and type signatures as a method in the superclass, then the method in the subclass _____ the method in the superclass.
    (A) Overloads
    (B) Friendships
    (C) Inherits
    (D) Overrides


    Answer: (D)

    Explanation:

    • When a method in a subclass has the same name and type signatures as a method in the superclass, then the method in the subclass overrides the method in the superclass.
    • Overloading allows different methods to have same name, but different signatures where signature can differ by number of input parameters or type of input parameters or both. Overloading is related to compile time (or static) polymorphism..
    • Friend Class A friend class can access private and protected members of other class in which it is declared as friend..
    • The capability of a class to derive properties and characteristics from another class is called Inheritance.

    So, option (D) is correct.

    What is the process of defining a method in a subclass having same name and type signature as a method in the superclass?

    Method overriding is when a subclass redefines a method of its superclass, of course the redefined method (of the subclass) has the same name and the same parameter types of the method of its superclass.

    When a method in a subclass has the same name and type signatures as a method in the superclass then the method in the subclass inherits the method in the super class?

    Answer: When methods in the superclass and subclass have the same name and signature is called Overridden methods.

    Can a subclass have a method with the same name and the same signature as its superclass?

    If your subclass defines a method with the same name and signature as a method in its superclass, the method in the subclass overrides the one in the superclass. Thus, the subclass does not inherit the method from its superclass.

    When a method in a subclass has the same name and return type as method in superclass it is known as?

    When a method in a subclass has the same name, same parameters or signature, and same return type(or sub-type) as a method in its super-class, then the method in the subclass is said to override the method in the super-class. Method overriding is one of the way by which java achieve Run Time Polymorphism.
