One of the most powerful concepts in object-oriented programming isencapsulation, which essentially means information hiding.

7. Create an example in which you use a library Let us look at creating a Math Library with public api with methods for product and difference of two integers. MathAPI class is shown as below: MathAPI 01 02 03 04 05 06 07 08 09 10 package org.javacodegeeks.math; public class Math...
There are many benefits to hiding information about attributes and methods using encapsulation in programming. One is that it prevents other developers from writing scripts orAPIsthat use your code. With encapsulation, users of a class do not learn how a class stores its data, and the developer...
Data encapsulation.This means that objects contain everything they need to function, including the object methods and any related data. Withdata encapsulation, the object can then make its interfaces available to other objects to enable them to use the object. Also, objects within a class can ke...
