The objective of the research work lies in estimating quality of the object oriented classes with respect to java. The research uses scorecarding as a technique to evaluate the quality of the java executables. The research works is divided into three main phases where the first phase is the development of the data extractor namely Class Breakpoint Analyzer which is responsible of fetching the data from the object oriented classes. The second phase of the research is the development of the Class Quality Scorecards. The optimal quality indicators (Object Oriented thresholds) are used to find the deviations of the object oriented parameters that are measured by the CBA. Based on the parametric measurement and comparison with the pre-defined threshold value, the Scorecards have been generated. Evaluation of coupling parameters, the coupling extractor has been developed to evaluate the coupling parameters to facilitate the decision about the refractoring of the classes which is carried out in the third phase of the research work. Both benchmark files and application files are used to generate the results. The statistical quantitative proof based on the output of the score cards.
