How to declare array in method

Question

I am currently having to write a method that takes in two parameters: an array of integers called data and an integer called num. The purpose of this method is to count the amount of times that number shows up in the array. I am having trouble figuring out how to declare the array in the method. I was wondering if there was any easier way that I did below:

Method

public static void countNumbers( int data[], int num ) {
        int count = 0;

        for(int i = 0; i < data.length; i++) {
            if(data[i] == num)
                count++;
        }
        if (count == 0)
            System.out.println("There are no " + num + "'s in the array.");
        if (count == 1)
            System.out.println("There is one " + num + " in the array.");
        if (count > 1)
            System.out.println("There are: " + count + " " + num + "'s in the array.");
}

Main Class

public static void main(String args[]) {
        int firstArray[] = {1,2,3,4,5};
        Methods.countNumbers(firstArray, 2);
    }

So I was wondering if you could directly declare the array within the countNumbers(data,num) any help would be appreciated!

I don't understand your question -- you declare the array in the method parameter and appear to do so appropriately. So what is this all about? What confuses you. — Hovercraft Full Of Eels, Apr 07 '17 at 01:05

If you don't reference it anywhere else (you don't need it anywhere else) just do Methods.countNumbers({1, 2, 3}, 2) — MCMastery, Apr 07 '17 at 01:13

Is that what you are looking for?

public static void main(String args[]) {
    Methods.countNumbers(new int[] {1,2,3,4,5}, 2);
}

This was exactly what I was looking for, thank you very much. I can not accept an answer just yet though! – Mason Salcido Apr 07 '17 at 01:10
