Introduction to inheritance and polymorphism

____ promotes reusability by allowing us to inherit attributes from a base / parent class to another class, which is known as the derived / child class.

• Polymorphism

• Inheritance

• Encapsulation

• Abstraction

Polymorphism is achieved in Java using

•  function/method overloading

•  this statement

•  nested loops

• break statement

If a class has multiple methods having the same name but different in parameters, it is known as ____ overloading.

• class

• object

• method

• data

____ means “of many forms”. It allows us to perform a single action with different outcomes and can be viewed as a way to reuse methods / operators to achieve different things.

• Encapsulation

• Looping

• Polymorphism

• Object

The following class exhibits which feature?

class Adder{  

    static int add(int a, int b){

        return a+b;

    }  

    static double add(double a, double b){

       return a+b;

    }  

} 

• Polymorphism

• Abstraction

• Operator overloading

•  None of the mentioned
