Naming convention

Packages : lowercase

In software companies and large projects where the packages might be imported into other classes,the names will normally be subdivided. Typically this will start with the company domain before being split into layers or features:

     Eg : package org.company.mycalculator

Classes : CamelCase ( Each new word begins with capital letter)

 Try to use nouns because a class is normally representing something in the real world

      Eg : class MyCustomer

Interfaces : camelCase :

They tend to have a name that describes an operation that a class can do

        Eg : interface MyCustomer

Note : can use " I " to distinguish interfces from others.

       Eg : interface IMyCustomer

  

Methods : MixedCase ( starting with lowercase ,after that eash new word begins with capital letter )

        Use verbs to describe what the mothod does :

       Eg : void myCustomer()

Variables : mixed case :

The names should represent what the value of the variable represents:

   Eg : String firstName

Only use short names when the variables are short lived ,Such as in for loops

Eg : for(int i=0;i<=3;i++){

// we use " i " only inside of the loop .

}

Constants : Uppercase :

       Eg : static final int AGE ;
