Value passed as parameter never read
Warning
New
Last modified: 03 December 2024Reports redundant method parameters that can be replaced with local variables.
If all local usages of a parameter are preceded by assignments to that parameter, the parameter can be removed and its usages replaced with local variables. It makes no sense to have such a parameter, as values that are passed to it are overwritten. Usually, the problem appears as a result of refactoring.
Example:
void test(int p) {
p = 1;
System.out.print(p);
}
After the quick-fix is applied:
void test() {
int p = 1;
System.out.print(p);
}

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
