Object-oriented technology has widely accepted as the preferred way for large as well as small-scale system design. By using this advanced technology we can develop software product of lower maintenance cost and higher quality. It is clear that the available traditional software metrics are insufficient for case of object-oriented software. As a result of that, a set of new object oriented software metrics came into existence.The software test metrics which are measure of quality of the code, are very important elements of quality driven testing. They help in assuring that whether the software is appropriate or not. Result shows, the best metrics suite which covers almost all the software quality assurance features is CK metrics. Measurement of structural quality of code is necessity for ensuring overall quality of the code. Cost of maintaining and developing software is highly affected by quality and complexity of the software. In this research paper we look into several object oriented metrics as well as general code quality metrics proposed by various well known researchers. These object oriented metrics and general code quality metrics are then applied to several java programs to analyze the structural code quality of software product. Software reliability, readability, maintainability, reusability can be calculated based on the values of such metrics. These results are used for improving overall quality of the code and helping in reduction of maintenance cost.
