According to the docs:
Nested enum types are implicitly
static.
So there's no need to declare them static explicitly.
public class Flower {
static enum Color { // Noncompliant; static is redundant here
RED, YELLOW, BLUE, ORANGE
}
// ...
}
public class Flower {
enum Color { // Compliant
RED, YELLOW, BLUE, ORANGE
}
// ...
}
