Question

In object oriented programming, the data and functions are wrapped together so that the data members should be accessed within the scope of a class. To adopt this principle, the data are declared with an access specifier. A class can also acquire some features from another class. This is called inheritance. Inheritance can be of different types. One type of inheritance allows acquiring the features of a base class into multiple targets. However, sharing multiple bases to a single target is not allowed in Java.

Based on the above discussion, answer the following questions:

1. What is the term used for wrapping data and functions as a unit?
   1. Inheritance
   2. Polymorphism
   3. Object
   4. Encapsulation
2. Name the access specifier that allows accessing data members within the scope of a class?
   1. public
   2. private
   3. protected
   4. secure
3. Which type of inheritance allows accessing a base into multiple targets?
   1. Hierarchical
   2. Single
   3. Multilevel
   4. Hybrid
4. Which type of inheritance is not allowed in Java?
   1. Multilevel
   2. Multiple
   3. Hierarchical
   4. Nested

Answer 1

1. iv. Encapsulation
2. ii. private
3. i. Hierarchical
4. iii. Multiple
