The article discusses a new method for measuring how well different parts of a computer program work together. This is important for making sure the program runs smoothly and can be easily changed if needed. The researchers looked at different ways to measure this "cohesion" and found that using certain metrics can help improve the quality of Java code. They also developed a tool called jPeek to help with this process. The main goal of the study was to create a method for using these metrics to analyze code effectively.
