This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Which of the following modifiers can be applied to a constructor? a. abstract b. final c. private d. protected e. public f. static g. synchronized h. transient i. volatile j. native k. strictfp l. None of the above. The answer exclude synchronized. However following code compiles and works. As question is saying which modifiers CAN be applied, it should be part of answer list.
Not so fast there, partner! That isn't even a constructor you've declared there! Once you provide a return type, you no longer have a constructor for class B, you have a method within class B named B. If you were to remove the return type, you'd have a constructor and the compiler will give you an error. Just to back that up, let's refer to the JLS, §8.8.3 Constructor Modifiers:
Unlike methods, a constructor cannot be abstract, static, final, native, strictfp, or synchronized.
