Java arrays default values: which four entries correctly describe default element values for the given types?

Introduction / Context:
When you create an array in Java, every element is automatically initialized to a type-specific default. This behavior differs for primitives and reference types.

Given Data / Assumptions:

• Types and proposed defaults: int → 0, String → ""null"" (string literal), Dog → null, char → '\u0000', float → 0.0f, boolean → true.

Concept / Approach:
Java default element values: numeric primitives → 0/0.0, char → '\u0000', boolean → false, reference types → null (not the string ""null"").

Step-by-Step Solution:

Verification / Alternative check:
Allocate new arrays and print default values; booleans print false, references print null.

Why Other Options Are Wrong:
Any set that includes String → ""null"" or boolean → true is incorrect.

Common Pitfalls:
Misunderstanding null vs. the string ""null""; assuming booleans default to true.
