Does not find specific number in array

I am trying to write a program that creates an array and fill it with int numbers(first method). In the end, it is supposed to see if a specific number is given in the array(second method). The problem is that the program does not run my if loops. I do not know why. The variable x is the number the program is looking for in the array and pos the position of the number in the array

public class Program {

    static int [] numbers= new int[100];
    
    public static void main(String [] args) {

        PrintWriter out = new PrintWriter(System.out);

        arrayConstruction();
        test(out);
        out.flush();
    }

    public static void arrayConstruction() {
        int x = 0;
        for (int i = 0; i < numbers.length; i++) {
            numbers[i] = x;
            x++;
        }
    }

    public static void test(PrintWriter out) {
        int x = 17;
        int pos = 0;
        if(pos != numbers.length) {
            if(numbers[pos] == x) {
                out.println("The number was found!");
                out.flush();
            }
            
            pos++;
        }
        
        else if(pos == numbers.length) {
            out.println("The number does not exist!");
            out.flush();
        }
    }
}

You forgot to add a loop to the test method, so it checks the first array's item only. E.g. you can use while loop.

public static void test(PrintWriter out) {
    int x = 17;
    int pos = 0;

    while (true) {
        if (pos != numbers.length) {
            if (numbers[pos] == x) {
                out.println("The number was found!");
                return;
            }

            pos++;
        } else if (pos == numbers.length) {
            out.println("The number does not exist!");
            return;
        }
    }
}

I think you should redesign your code by splitting different activities with separate methods. It makes your code clear to understand.

public class Main {

    public static void main(String[] args) {
        int[] arr = createArray(100);
        System.out.println(isNumberExist(arr, 17) ? "The number was found!"
                                                  : "The number does not exist!");
    }

    public static int[] createArray(int total) {
        int[] arr = new int[total];
        Random random = new Random();

        for (int i = 0; i < arr.length; i++)
            arr[i] = random.nextInt(arr.length);

        return arr;
    }

    public static boolean isNumberExist(int[] arr, int x) {
        for (int i = 0; i < arr.length; i++)
            if (arr[i] == x)
                return true;

        return false;
    }

}
