Given: 3. public class TestDays { 4. public enum Days { MON, TUE, WED }; 5. public static void main(String[] args) { 6. for(Days d : Days.values() ) 7. ; 8. Days [] d2 = Days.values(); 9. System.out.println(d2[2]); 10. } 11. } What is the result? (Choose all that apply.)

  1. TUE

  2. Wed

  3. The output is unpredictable

  4. Compilation fails due to an error on line 4

  5. Compilation fails due to an error on line 6

  6. Compilation fails due to an error on line 8

B Correct answer
Explanation

The enum Days has values: MON(0), TUE(1), WED(2). The array d2 from Days.values() has these in declaration order. Accessing d2[2] returns the third element WED. Option B is correct. The code compiles and runs fine - Days.values() is valid, enums can have arrays, and accessing index 2 is within bounds (array length is 3). Option A is TUE (index 1). Option C is wrong - enum order is fixed.
