Answer 1

Answer:

There are 4 OOPS concepts in Java. Inheritance, Encapsulation, Polymorphism and Abstraction.

Answer 2

Answer:

16-B.Method overloading

17-C.Operator overloading

Explanation:

• Creating more than one method or a function that has a same name but different signatures or parameters in the same class is called method overloading. Method overloading is also called early binding or compile time polymorphism or static binding.
• Polymorphism: Polymorphism (or operator overloading) is a manner in which OO systems allow the same operator name or symbol to be used for multiple operations. That is, it allows the operator symbol or name to be bound to more than one implementation of the operator.
• It allows you to provide an intuitive interface to users of your class, plus makes it possible for templates to work equally well with classes and built-in/intrinsic types. Operator overloading allows C/C++ operators to have user-defined meanings on user-defined types (classes).
