In this proposed paper it described about the code clone detection using the fine granularity technique called frequent pattern growth algorithm. Here it used for detecting that the type clones which are known as functional clones. In software project it mainly detect the software code .it helps to extract the methods using frequent occurrences in patterns and names from that files it extracts the common methods as libraries In addition to that it proposes maintenance To be performed such as adaptive maintenance, corrective maintenance, perfective maintenance for the sample project.
