Maybe it is a naive question, but I am running the source code of a java application on eclipse and I need to extract one specific functionality from all the application. Is there any way to highlight or identify the chunk of codes which were not ran after an execution?. I am using Eclipse 2018-09.

Thank you so much.

  • I am not sure what are you asking for. Anyway, you can put `System.out.println` statement with some random text in your block to make sure whether it is executed or not. – Tanzeel Sep 18 '19 at 04:14

    Run the program with code coverage option? See [Eclemma](http://www.eclemma.org/) – Ashvin Sharma Sep 18 '19 at 04:27
  • But note: "unrun" code depends on how exactly your "drive" your application when measuring coverage. – GhostCat Sep 18 '19 at 05:06

One way to identify which code were executed is to write a test case and run java code coverage maven plugin or run sonar for the test case, if you are using maven project. jacoco-maven-plugin is the plugin name. You can check more details in https://medium.com/capital-one-tech/improve-java-code-with-unit-tests-and-jacoco-b342643736ed.
