Detect malodorous software pattern and refactor them

Includes bibliographical references (p. 45).Code smells are characteristics of the software that may indicate a code or design problem that can make software hard to evolve and maintain. In layman terms, it signals flaws in the core foundation or architecture of the software that can cause any number of more serious problems -- from usability and runtime performance to supportability and enhancement. Code smells can be detected and eliminated using refactoring techniques. Refactoring is the process of making changes in existing source code without changing the functional behavior. In this thesis an attempt is made to identify code smells using software. This thesis report discusses some of the code smells with examples and the technique used to detect them. Further this thesis report also discusses refactoring techniques which could be used to detect and remove these code smells and an investigation is also done on the refactoring techniques provided by eclipse for these code smells
