Exception_Handling

Exception: An unwanted unexpected event that disturbs normal flow of the program is called exception.

Example:

•    SleepingException 
•    TyrePunchuredException 
•    FileNotFoundException ...etc

It is highly recommended to handle exceptions. The main objective of exception handling is graceful (normal) termination of the program.

Object_Oriented_Programming_(OOPS)

Data Hiding

• Our 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.

Example:

 class Account  {
       private double balance; 
        ......................; 
        ......................;
   }  

• After providing proper username and password only , we can access our Account information.
• The main advantage of data hiding is security.

Note: 

• Recommended modifier for data members is private.
