Encapsulation is useful in object-oriented programming since objects hermetically seal the data structures they control. As a result, the program's objects divide system memory into disjoint blocks, each of which is accessible only by the object routines that control it. With this approach, modifying and creating programs are less likely to encounter errors since encapsulation is a valuable tool for structuring the program. In addition, the program becomes easier to read for the programmer. (Cohen, 1984). An easy way to understand encapsulation is to visualize a capsule that consists of two parts that we can insert something into before sealing it tightly. To better understand, capsules will be represented by objects or classes. As part of programming, this process of sealing something is called encapsulation.

No matter what programming language is used, encapsulation has the same principles and reasons for being used. When creating objects, constructors, or classes, most languages require the keyword ' public ' to be replaced by the keyword ' private.' The programmer may have to make additional effort in some programming languages, such as making each variable or method private, which is worth remembering.

 

Once data is encapsulated, it functions as independent, isolated blocks of code that cannot be changed from the outside, so nobody or nothing can access them. Consequently, a class, constructor, or object cannot modify values or data behavior because no functions or variables are allowed inside them. It is important for corporations and companies to ensure that sensitive or critical data is protected with encapsulation, which cannot be modified in any way. Furthermore, this method is convenient for Developers because it dramatically accelerates and improves the performance of the entire program, as well as reducing the possibility of introducing errors in the code and reducing debugging time.
