How do I implement immutable parameters in my code?

To implement immutable parameters, you can use the final keyword in Java or const in JavaScript. This prevents reassignment.

Can you give me an example in Java?

Sure! Here's a simple example:

public class Example {
    public void display(final int number) {
        // number cannot be reassigned here
        System.out.println(number);
    }
}

What about in Python?

In Python, you can use tuples or frozensets to create immutable collections. For parameters, you can simply avoid reassigning them.

Are there any benefits to using immutable parameters?

Yes, immutable parameters can help prevent bugs, make your code easier to understand, and improve performance in some cases.
