pascalCase and camelCase Naming System

Introduction

pascalCase and camelCase are naming recommendations and it is good practice to follow this always. Everyone is programmer but the one who follow these systems is good programmer. pascalCase and camelCase naming conventions is purely based on accessibility of class members. In other word, how to write method or field name if he has public accessibility or how to write if he has private accessibility.

Public Naming Recommendation

Identifiers that are public should start with a capital letter. Look at example given below, Addition field and Add methods given below starts with capital 'A' (not small 'a') because it's public.

This system is known as the PascalCase naming scheme because it was first used in the Pascal language.

class Calc

{

    public int Addition;

    public double Add()

    {

        //statements

    }

}

Private Naming Recommendation

Identifiers that are private should start with a small letter. Look at example given below, addition field and add methods given below starts with small 'a' (not capital 'A') because it is private. This system is known as the camelCase naming scheme.

class Calc

{

    private int addition;

    private double add()

    {

        //statements

    }

}

Remember this recommendation: class names should start with a capital letter. Never declare two public class members whose names differ only in case. If you do so then, developers who is using other languages that are not case sensitive, such as Microsoft Visual Basic, will can't use our class.
