Reuse of local variable
Reports local variables that are "reused" overwriting their values with new values unrelated to their original use.
Such a local variable reuse may be confusing, as the intended semantics of the local variable may vary with each use. It may also be prone to bugs if due to the code changes, the values that have been considered overwritten actually appear to be alive. It is a good practice to keep variable lifetimes as short as possible, and not to reuse local variables for the sake of brevity.

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

Example:
void x() {
String s = "one";
System.out.println("s = " + s);
s = "two"; //reuse of local variable 's'
System.out.println("s = " + s);
}
