Code Inspection: Redundant local variable

Reports an unnecessary local variable that does not make a function more comprehensible:

  • a local variable that is immediately returned

  • a local variable that is immediately assigned to another variable and is not used anymore

  • a local variable that always has the same value as another local variable or parameter.

Use the checkbox below to have this inspection ignore variables that are immediately returned or thrown. Some coding styles suggest using such variables for clarity and ease of debugging.

Suppress an inspection in the editor

  1. Place the caret at the highlighted line and press Alt+Enter or click the Intention action icon.

  2. Click the arrow next to the inspection you want to suppress and select the necessary suppress action.
