2: String s1 = "java"; 3: StringBuilder s2 = new StringBuilder("java"); 4: if (s1 == s2) 5: System.out.print("1"); 6: if (s1.equals(s2)) 7: System.out.print("2");
❌ A. 1 ❌ B. 2 ❌ C. 12 ❌ D. No output is printed. ❌ E. An exception is thrown. ✅ F. The code does not compile
Explanation: The question is trying to distract you into paying attention to logical equality versus object reference equality. It is hoping you will miss the fact that line 4 does not compile. Java does not allow you to compare String and StringBuilder using ==.
