A public class Actor { String[] characterName = new String[3]; { characterName[0]
= "Captain Video"; characterName[1] = "Quizmaster"; characterName[2]
= "J.C. Money"; characterName[3] = "Jersey Joe"; } }

B public class Actor { String[] characterName = new String[1..4]; { characterName[0]
= "Captain Video"; characterName[1] = "Quizmaster"; characterName[2]
= "J.C. Money"; characterName[3] = "Jersey Joe"; } }

C public class Actor { String characterName = new String[4]; { characterName[0]
= "Captain Video"; characterName[1] = "Quizmaster"; characterName[2]
= "J.C. Money"; characterName[3] = "Jersey Joe"; } }

D public class Actor { String[] characterName = new String[4]; { characterName[0]

Explanation:

D. The array declaration and element assignments are used appropriately and compile without error.

A, B, and C are incorrect.

A compiles with an ArrayIndexOutOfBoundsException exception thrown at runtime.

This is because the array index characterName[3] is out of bounds.

B fails to compile because only an integer is expected in the box brackets.

C fails to compile because the box brackets that are needed to create the array are missing.
