Refactoring is the process of improving the code of the software without affecting the external behavior of the code only by reconstruct the internal structure . It makes code cleaner, clearer, simpler or in other words, clean up the code. It also improves the quality of code then it became more reliable and easy to maintain through lifecycle of software. Refactoring has become renowned concept in software development process. The IDE (Integrated Development Environment) highly prefer this technique. Researches on refactoring technique have improved now a day. Beyond that, this particular technique is used to improve different functions of application software. It mainly speed up the function and helps to get the output much faster. In this proposed work Feature Oriented Dependency (FOD) tool is created used for refactoring process established on a chemical reaction optimization meta heuristic approach to discover the appropriate refactoring resolutions.
