Unnecessary 'default' for enum 'switch' statement
Reports enum switch
statements or expression with default
branches which can never be taken, because all possible values are covered by a case
branch.
Such elements are redundant, especially for switch
expressions, because they don't compile when all enum constants are not covered by a case
branch.
The language level needs to be configured to 14 to report switch
expressions.
The provided quick-fix removes default
branches.
Example:
enum E { A, B }
int foo(E e) {
return switch (e) {
case A -> 1;
case B -> 2;
default -> 3;
};
}
After the quick-fix is applied:
enum E { A, B }
int foo(E e) {
return switch (e) {
case A -> 1;
case B -> 2;
};
}

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
UnnecessaryDefault
Use the Only report switch expressions option to report only redundant default
branches in switch expressions.
