When I am in a .java file the unused code is usually grayed out or has a green underline saying this code will probably (probably because of some weird JNI/Reflection corner cases) be unused. But I have this project with thousands of Java files and I want to find ALL INSTANCES of such probable-unused codes. How can I do that in IntelliJ IDEA?

Just use Analyze | Inspect Code with appropriate inspection enabled (Unused declaration under Declaration redundancy group). @CrazyCoder This shows unused fields and methods too, any way to show only unused classes? My 2 cents: on IntelliJ 2016.3. 4 the option is under Analyze > Run Inspection By Name.
In IntelliJ, in a . java file, some unused code is greyed out indicating that the declared variable or function is never used. Unused imports are removed using Ctrl+Alt+O.
Just use Analyze | Inspect Code with appropriate inspection enabled (Unused declaration under Declaration redundancy group).
Using IntelliJ 11 CE you can now "Analyze | Run Inspection by Name ... | Unused declaration"
