Java coding Standards - Code convention

In this tutorial you will learn how to make more strength to you java classes by adding code convention.

What is Code Convention?

Code convention place a important role while you are writing a simple Hello World java class or Software project.

Code conventions are at the following places

1. File Names

> File name should be a minimum of 8 character .

> Every word should be begin with Upper case letter like MyDevice.java, HelloWorld.java , LearnProgrammingJava.java

2.Packages Names

> Package should be always in lowercase letters like itsmypackage or com.project.ui or com.client or com.server

3.Class Names

> Class Name are very similar to file name else your jvm (Java virtual Machine) will not recognize..

4.Interface Names

> Interface are like a small method which doesn't have implementation within a method and you can write interface like a method variables.

> Every java will have atleast on class or interface

5.Constants

> Constant is the variable which cannot be modified once the value is set like final variable that help you to make the value is constant.

> Always define final variable with upper case letter and seprate each word with underscore like MINIMUM_DEPOSIT_AMOUNT or COLOR_RED

6.Variables

Pubic Variables

> Variable name are always start with lowercase letter and after that each word should begin with Upper case letters like textBox, labelForName, debitAmount,

password.

Private Variables

> Private variable is similar to public variables but for differentiating we add _ at the end of variable like textBox_, labelForName_ , debitAmount_

Boolean Variables

> Always use prefix for boolean variable like 'is' and the your word first letter with Upper case letter and then lower case

like this boolean isUserNameCorrect or isVisible or isFinished

Iterate Variables

> Try to use i , j , k and so on for Iterator varibles

7.Method Names

> Method name should always begin with lowercase letter and then each word will begin with upper case letter like calculateAmount() or getUserName()
