1Z0-811 Java Basics and Syntax Practice Question

A developer uses the following array initialization: int[] nums = new int[]{1, 2, 3}; Which of the following is true?

⚠ Common exam trap

The 1Z0-811 exam often tests the distinction between array declaration with an initializer list (which must be in a single statement) and the anonymous array syntax shown here, leading candidates to mistakenly think the syntax is invalid or that the array has default values.

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

The array has length 3.

The array initialization `int[] nums = new int[]{1, 2, 3};` explicitly creates an array of length 3, containing the elements 1, 2, and 3. The syntax is valid and the array is not initialized with default values; it is initialized with the specified literal values.
