In Java, which off the following statements is/are true?
S1: The ‘final’ keyword applied to a class definition prevents the class from being extended through derivation
S2: A class can only inherit one plus but can implement multiple interfaces
S3: Java permits a class to replace the implementation of a method that it has inherited. It is called method overloading.
Code:
Method Overloading is a feature that allows a class to have more than one method having the same name, if their argument lists are different. It is similar to constructor overloading in Java, that allows a class to have more than one constructor having different argument lists.
For points 1 and 2, keep basic understanding of classes, abstract classes and inheritance. For this, refer This Document.
For Java Overriding, this document is enough to clear concepts.
