Which four options describe the correct default values for array elements of the types indicated?
  1. int -> 0
  2. String -> "null"
  3. Dog -> null
  4. char -> '\u0000'
  5. float -> 0.0f
  6. boolean -> true

A 1, 2, 3, 4

B 1, 3, 4, 5

C 2, 4, 5, 6

D 3, 4, 5, 6

ANS:B - 1, 3, 4, 5

(1), (3), (4), (5) are the correct statements. (2) is wrong because the default value for a String (and any other object reference) is null, with no quotes. (6) is wrong because the default value for boolean elements is false.
