How Can I Achieve Immutability with Primitive Arrays in Java?

An Immutable Alternative to Primitive Arrays in Java

In Java, primitive arrays can be declared final, but this does not prevent their elements from being modified. For truly immutable arrays, consider alternative data structures.

Q: Is there an immutable alternative to primitive arrays in Java?

A: Not with primitive arrays. You'll need to use a List or other data structure that provides immutability.

Example:

<code class="java">List<Integer> items = Collections.unmodifiableList(Arrays.asList(0, 1, 2, 3));
// items is now immutable</code>
