In this article, Programming Assignment Help will discuss the various advantages of data encapsulation. You will get this topic in your academics and at that time you will need someone to help you to give expert guidance. So, let us begin with the advantages of Data Encapsulations.
Data Encapsulation helps to separate the irrelevant functions by making flexible code. One can easily change the code to maintain. It serves with better control of the data. It makes the way easier to achieving low coupling. Data encapsulation has several advantages-
The focus of data encapsulation is to keep data safe and hidden from the outside public. Through this mechanism, the role of objects gets more defined and clear perspective. In this context, data encapsulation is a contract based on two objects. Therefore, the invoker object must agree to send a message in a proper format to process the message in the pre-specified format by the invoked object. Thus, accidental corruption gets prevented.
Sometimes, the format of data protection needs to be changed for some reasons. If the new requirements occur, the encapsulated code can easily change as the mechanism is very flexible. User can restrict the permission for any variable or method using the encapsulation. If only read permission is given to any user, the user can only read the data. User cannot modify the values.
If the other objects need to operate the same type of applications, the pre-encapsulated code can be used in multiple times. Public services in the updated software make easy to understand the pre-encapsulated code and use it again to develop the software.
Example- the personage can be used repeatedly whenever it is required using in the same type of object.
Data Encapsulation uses separate units, i.e. interfaces, classes, mechanism, setters et cetera. Therefore, the user can easily update any single part of the application. It does not affect other parts. Besides this, maintaining the time of the application will get reduce. Hence, it can be said that data encapsulation promotes maintenance as the code changes happen independently.
- Control Over The Data:
It provides the power to control the data.
Example- if a user needs to set the id-value, greater than 100, he/she can easily update the setter mechanism by witting over the logic. This logic cannot be stored in negative numbers.
- Easy to Test:
Testing the encapsulated data is very easy. Therefore, it is a great process for testing the unit.
- The Independence of Each Object:
by using public method one can easily change the method of objects. It need not to break the code that is pre-settled. The code considered the object as a “Black-Box”.
