Encapsulation in Java - Learn Java

Encapsulation in Java - Learn Java

Encapsulation Real Time Example

Binding a data and corresponding method in a single unit is called encapsulation.
If any class follows data hiding and abstraction such type of class is called encapsulated class.

ENCAPSULATION= ABSTRACTION+DATA HIDING

The Main Advantage of Encapsulation.

1. we can achieve security.

      2. it is improves maintainability and modularity of application.

The Main Disadvantage of Encapsulation.

    1.it is increases length of the code and slow down execution.

Every Data member should be declared as private and for every member we have to maintain 
 getter and setter method.

Abstraction in Java - Learn Java

Abstraction in Java - Learn Java

Abstraction in oops with Example

1. Hide internal implementation and just show the set of service

          is called abstraction. 

The Main Advantage of Abstraction

1. We can achieve security as we are not highlighting our internal implementation.
2. it improves maintainability of the application.
3. it improves modularity of the application.
4.  it improves easyness to use our system.

Use of interface we can implement abstraction.

What is data hiding in a program? - Learn Java

What is data hiding in a program? - Learn Java

• Over internal data should not go out directly that is outside person can't access our internal data directly.
• By using private modifier we can implement data hiding .  

Data Hiding In Java Example Program.

EXAMPLE 
       
        class Account
       {
           private double balance;
           ---------------------------;
          ----------------------------;
        }
    After providing proper username and password only, we can access our Account 
    information.
   Main advantage of data hiding is security.

Java is a general-purpose programming language that is class-based,object-oriented (although not a pure object-oriented language, as it contains primitive types and designed to have as few implementation dependencies as possible. It is intended to let application developers write once, run anywhere (WORA),meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture.
