Why have Naming Conventions ?

A naming convention is a rule to follow as you decide what to name your identifiers (e.g. class, package, variable, method, etc).Different Java programmers can have different styles and approaches to the way they program. By using standard Java naming conventions they make their code easier to read for themselves and for other programmers. Readability of Java code is important because it means less time is spent trying to figure out what the code does, leaving more time to fix or modify it.

We Should follow naming conventions because of the following reasons.

+ A program is written once and read many times.

+ During debugging

+ When adding to a program

+ When updating the program

+ When trying to understand the program

To illustrate the above points it's worth mentioning that most software companies will have a document that outlines the naming conventions they want their programmers to follow. A new programmer who becomes familiar with those rules will be able to understand code written by a programmer who might have left the company many years before hand.So anything that makes a program more readable and understandable saves lot of time even in short run.
