Principles of Object Oriented Programming

Principles to keep in mind

  1. Encapsulate what varies.
  2. Code to the interface, not to the implementation.
  3. Favor composition over inheritance.
  4. Strive for loosely coupled designs between objects that interact.
  5. Classes should be open for extension but closed for modifications.
  6. Depend on abstractions. Do not depend on concrete classes.
  7. A class should have only one reason to change.

MTA 98-361: How I passed MTA - Software Development Fundamentals?

MTA 98-361: How I passed MTA - Software Development Fundamentals? :) Let’s Define Microsoft Technology Associate     (c) Microsoft     (c) Useful Link Who should take this exam?     (c) Microsoft What Skills do I need to study for the Exam? Check on this :  Microsoft How did I prepare?

What is the difference between Pascal Case and Camel Case?

Pascal case is a subset of Camel Case where the first letter is capitalized. That is,  userAccount is a camel case and  UserAccount is a Pascal case. The conventions of using these are different. You use camel case for variables and Pascal case for Class names or Constructors. It is easy to remember. Pascal is a proper noun so capitalize the first letter. camel is a common noun, so you do not capitalize the first letter. Talking from a programmer's perspective,  PascalCase  means the first char should be capitalized while  camelCase  means the first char should be lowercased.
