what is the use of pmd tool in java
PMD (software) PMD is an open source static Java source code analyzer that reports on issue found within application code. PMD includes built-in rule sets and supports the ability to write custom rules. PMD does not report compilation errors, as it only can process well-formed source files. Issues reported by PMD are rather inefficient code, or bad programming habits, which can reduce the performance and maintainability of the program if they accumulate.
AP Computer Science A GridWorld is a computer program case study written in Java that was used with the AP Computer Science program from 2008 to 2014.[7] It serves as an example of object-oriented programming (OOP). GridWorld succeeded the Marine Biology Simulation Case Study, which was used from 2000â€“2007. The GridWorld framework was designed and implemented by Cay Horstmann, based on the Marine Biology Simulation Case Study. The narrative was produced by Chris Nevison and Barbara Cloud Wells, Colgate University.
