An empirical analysis of software changes on statement entity in java open source projects

Software projects keep changing all the time. Understanding the nature of the changes can help build higher quality projects. In this paper, the authors studied software changes on a new entity, statement. They found some types of statements are more likely to change than others. Furthermore, the authors studied software changes to fix bugs and also found some types of statements are more likely to change than others to fix bugs. These statements are more likely to cause bugs, which should be paid more attention to.
