In Java, which option both declares an int array and initializes it immediately with five specific numbers?

Introduction / Context:
Arrays in Java are objects with fixed length. You can declare and initialize them in one statement using an initializer list, which is common for known small datasets.

Given Data / Assumptions:

• We need both declaration and immediate initialization with five numbers.
• Java syntax, not C/C++ custom array syntax, applies.

Concept / Approach:
Use the brace form: type[] name = {v1, v2, ...}. This creates the array object and fills it with the specified values. The length is inferred from the list.

Step-by-Step Solution:

Verification / Alternative check:
Print a[0..4] after option B; it shows the listed values, not zeros.

Why Other Options Are Wrong:
They either lack initialization values or use invalid types/syntax.

Common Pitfalls:
Confusing Java with C-style declarations or assuming Array is a built-in type to construct directly.

Final Answer:
int [] a = {23, 22, 21, 20, 19};
