Question

I was wondering if it was better to have a method for this and pass the Array to that method or to write it out every time I want to check if a number is in the array.

For example:

public static boolean inArray(int[] array, int check) {

    for (int i = 0; i < array.length; i++) {
        if (array[i] == check) 
            return true;
    }

    return false;
}

Thanks for the help in advance!

Answer 1

You should definitely encapsulate this logic into a method.

There is no benefit to repeating identical code multiple times.

Also, if you place the logic in a method and it changes, you only need to modify your code in one place.

Whether or not you want to use a 3rd party library is an entirely different decision.
