An AntiPattern is opposite of a Design Pattern. It is a common

practice in an organization that is used to deal with a recurring

problem but it has more bad consequences than good ones.

AntiPattern can be found in an Organization, Architecture or

Software Engineering.

Some of the AntiPatterns in Software Engineering are:

1. Gold Plating: Keep on adding extra things on a working

solution even though these extra things do not add any

additional value.

2. Spaghetti Code: Program that are written in a very

complex way and are hard to understand due to misuse of

data structures.

3. Coding By Exception: Adding new code just to handle

exception cases and corner case scenarios.

4. Copy Paste Programming: Just copying the same code

multiple times rather than writing generic code that can be

parameterized
