Redundant local variable
Reports unnecessary local variables that add nothing to the comprehensibility of a method, including:
Local variables that are immediately returned.
Local variables that are immediately assigned to another variable and then not used.
Local variables that always have the same value as another local variable or parameter.
Example:
boolean yes() {
boolean b = true;
return b;
}
After the quick-fix is applied:
boolean yes() {
return true;
}

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
UnnecessaryLocalVariable
Configure the inspection:
Use the Ignore immediately returned or thrown variables option to ignore immediately returned or thrown variables. Some coding styles suggest using such variables for clarity and ease of debugging.
Use the Ignore variables which have an annotation option to ignore annotated variables.
Here you can find the description of settings available for the Redundant local variable inspection, and the reference of their default values.
