Encapsulation in java

Encapsulation:

• Data encapsulation is used to hide the implementation details from users.
• If a data member is private it means it can only be accessed within the same class. 
• No outside class can access private data member (variable) of other class.

Syntax:

1. class class_name

   {

   private data_members;

   public methods()

   {

   }

   }

Example program:

1. class Account {

       private int account_number;

       private int account_balance;

    

       public void show_Data() {

           account_number=13456;

           account_balance=5000;

           System.out.println("Before deposit of "+"account XXXXX"+account_number+" number of balance :"+account_balance);

       }

    

       public void deposit(int a) {

           if (a < 0) {

               System.out.println("Given amount is wrong...");

           } else

               account_balance = account_balance + a;

           System.out.println("After deposit of current balance :"+account_balance);

       }

   }

    

   class Encapsulation{

       public static void main(String args[])

       {

           Account ac=new Account();

           ac.show_Data();

           ac.deposit(200);

       }

   }
