advantages and disadvantages of encapsulation in java
How to encapsulate variables in Java?
Encapsulation can be achieved by Declaring all the variables in the class as private and writing public methods in the class to set and get the values of variables. It is more defined with the setter and getter method. Data Hiding: it is a way of restricting the access of our data members by hiding the implementation details.
What is encapsulation in object oriented programming?
Encapsulation is one of the key features of object-oriented programming. Encapsulation refers to the bundling of fields and methods inside a single class. It prevents outer classes from accessing and changing fields and methods of a class. This also helps to achieve data hiding. In the above example, we have created a class named Area.
What is the difference between abstraction and encapsulation in Java?
In Java, the process of abstraction is done using interfaces, classes, abstract classes, fields, methods and variables. Everything is an abstraction. Encapsulation is the process of hiding information details and protecting data and behavior of an object from misuse by other objects.
What are the disadvantages of encapsulation in Java?
The major disadvantage of encapsulation in Java is it increases the length of the code and slows shutdown execution. Data hiding in Java is an important principle of object-oriented programming system (OOPs). It prevents to access data members (variables) directly from outside the class so that we can achieve security on data.
Realtime Example of Encapsulation in Java
Realtime Example 1: School bag is one of the most real examples of Encapsulation. School bag can keep our books, pens, etc. Realtime Example 2: When you log in your email accounts such as Gmail, or Yahoo Mail, there is a lot of internal processes taking place in the backend and you have no control over it. When you enter the password for logging, t
How to Achieve Or Implement Encapsulation in Java
There are two important points whereby we can achieve or implement encapsulation in Java program. 1. Declaring the instance variable of the class as private so that it cannot be accessed directly by anyone from outside the class. 2. Provide the public setter and getter methods in the class to set/modify the values of the variable/fields. scientecheasy.com
Advantage of Encapsulation in Java
There are the following advantages of encapsulation in Java. They are as follows: 1. The encapsulated code is more flexible and easy to change with new requirements. 2. It prevents the other classes from accessing the private fields. 3. Encapsulation allows modifying the implemented code without breaking other code that has implemented the code. 4
Disadvantage of Encapsulation in Java
The major disadvantage of encapsulation in Java is it increases the length of the code and slows shutdown execution. scientecheasy.com
Data Hiding in Java
Data hiding in Java is an important principle of object-oriented programming system (OOPs). It prevents to access data members (variables) directly from outside the class so that we can achieve security on data. This oops feature is called data hiding in Java. For example, after providing proper username and password, you can able to access your Gm
How to Achieve Data Hiding programmatically?
By declaring data members (variables) as private, we can achieve or implement data hiding. If the variables are declared as private in the class, nobody can access them from outside the class. The biggest advantage of data hiding is we can achieve security. Key points: 1. We highly recommended it to declare data members as private in the class. 2.
Tightly Encapsulated Class in Java
If each variable is declared as private in the class, it is called tightly encapsulated class in Java. For a tightly encapsulated class, we are not required to check whether the class contains getter and setter method or not and whether these methods are declared as public or not. For example: Solve the following questions to understand the concept
Java Encapsulation Example Programs
Let’s take some example programs based on encapsulation in Java. Program code 1: In this example program, we have declared a private variable name in the class Student. So, the data member from outside the class cannot be accessed directly like this: To remove the compilation error problem from the above code, we need to call the getter, getName(),
