Basic Operations to performed in java application

Using only programming language we performs three operations in developing logic.

1. Reading and Storing input data.
2. Doing calculations for modifying data and generating output.
3. Controlling modifications.
4. Storing output permanently or printing it on console.

To perform first three operations every programming language contains three concepts.

1. Datatypes: used to store data temporarily.
2. Operations: For doing calculations.
3. Control Statements: Used for validating and controlling modifications.

In edition 2 above three concepts we also has more concepts to perform below tasks.

1. Reading input values from end user : IO Streams/ AWT.
2. Sending multiple values at a time to another application : Arrays and Collections .
3. Processing all requests at a time concurrently : Multi Threading .
4. Handling user mistakes and user understandable message : Exception Handling.
5. Sending and Reading data from Networking : Networking.
6. Storing data or output permanently : IO Streams and JDBC.
7. Executing logic in server system via web protocol : Servlets or JSP.
8. Executing logic in server system via distributed protocols : RMI and EJB.
9. Organizing logic Development by making it reusable from multiple applications by writing single program to execute method from different sub classes of an object : OOPS , LCRP , MVC.
