IDEA find unused code 2019-09-21 05:19

There are many unused code in my project. Whenever I see useless code, I will remove them. I think this is too inefficient. Fortunately, I found that IDEA can help me discover all the useless code in the project. In this blog I will show you how to use this feature.

Click Analyze -> Inspect Code choose the project you want to deal with. The more projects you choose the slower IDEA handle them.

After running the Analyze you will get the output in Inspection window. You can find unused code in Declaration redundancy -> Unused declaration

There are many others "issue" in Inspection window. You can handle them according to your own situation.
