39. What are the wrapper classes for the primitives boolean, char, short, int, and double?
A. Boolean, Char, Short, Integer, Double
B. Boolean, Character, Short, Int, Double
C. Boolean, Char, Short, Int, Double
D. Boolean, Character, Short, Integer, Double
D. The wrapper class reference types use the full spelling of the type names beginning with a capital letter. The full set of wrapper classes is Boolean, Character, Byte, Short, Integer, Long, Float, and Double.
A, B, and C are incorrect. Classes named Char and Int do not exist. The appropriate wrapper classes are named Character and Integer.
