Missing break statement in switch causes fallthrough

BugFind the bug and fix the code

What it should do

Determine access level string based on code. Example: getUserAccessLevel(1) -> "ADMIN"

What happens instead

Case 1 falls through to case 2, returning "USER" instead of "ADMIN"

public class Main {
    public static String getUserAccessLevel(int code) {
        String level = "GUEST";
        switch (code) {
            case 1:
                level = "ADMIN";
                // Missing break causes fallthrough into case 2
            case 2:
                level = "USER";
                break;
            default:
                level = "GUEST";
        }
        return level;
    }

    public static void main(String[] args) {
        System.out.println(getUserAccessLevel(1));
    }
}

Test a custom input to verify an edge case (e.g. empty lists, negative numbers, duplicates).

This bug belongs to the logic errors pattern

The wrong operator, an inverted condition, a formula the right way round but backwards.
