Given this enum declaration: 1. enum Alphabet { 2. A, B, C 3. } 4. Examine this code: System.out.println(Alphabet.getFirstLetter()); What line should be written at line 3 to make the code print A?

Question

Options

• AString str = getFirstLetter(). (return A.toString())
• Bstatic String getFirstLetter() { return Alphabet.values()[1].toString(); }
• Cstatic String getFirstLetter() { return A.toString(); }
• DString getFirstLetter(). (return A.toString())

• A
  4% (1)
• B
  4% (1)
• C
  81% (22)
• D
  11% (3)

Explanation

Option C is correct because getFirstLetter() must be static (called on the class itself via Alphabet.getFirstLetter(), not on an instance), and within an enum body, you can reference other enum constants like A directly without qualification, so A.toString() returns "A".

Why the distractors fail:

• A - missing static, making it an instance method; also the syntax getFirstLetter(). (return ...) is invalid Java.
• B - is static and syntactically valid, but values()[1] returns the second element (B, since arrays are 0-indexed), not A (values()[0]).
• D - same problem as A: missing static, so it can't be called as Alphabet.getFirstLetter().

Memory tip: When you see a method called on the class name (not an object), it must be static - eliminate any option without it immediately. Then double-check array indices: values()[0] = first constant, values()[1] = second.
