Answer 1

Answer:

ALL THESE OPTIONS ARE WRONG

BUT I AM CHOOSING FALSE

BUT THE CORRECT ANSWER:

From the Java Language Specification: Each class variable, instance variable, or array component is initialized with a default value when it is created (§15.9, §15.10): For type byte, the default value is zero, that is, the value of (byte)0 . For type short, the default value is zero, that is, the value of (short)0 .
