Code Inspection: Redundant local variable

Reports unnecessary local variables, which add nothing to the comprehensibility of a function. Variables caught include local variables which are immediately returned, local variables that are immediately assigned to another variable and then not used, and local variables which always have the same value as another local variable or parameter.

Use the checkbox below to have this inspection ignore variables which 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. Position 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.
