How to fix my Even-Odd Program java code it writes even or odd but also the number

package practıce1.array;
public class PRACTICE1ARRAY {
    public static int evenorodd(int a) {
    @author Başar Ballıöz
        if (a % 2 == 0) {
            System.out.println("Number Is Even");
        }
        else {
            System.out.println("Number Is Odd");
        }
        return a;
    }

    public static void main(String[] args) {

       int[] arr = new int[] {2,7,9,10,22,31};
       for (int i = 0; i < arr.length; i++) {
            System.out.println("Element Of Index " + i + " = " + arr[i]);
        }    
        System.out.println(evenorodd(arr[0]));    
    }
}

Output:

run:
Element Of Index 0 = 2
Element Of Index 1 = 7
Element Of Index 2 = 9
Element Of Index 3 = 10
Element Of Index 4 = 22
Element Of Index 5 = 31
Number Is Even
2

I dont want to see value of number. I just want to see is number even or odd ? I think it`s causing because of a mistake which is happened in method

Your evenorodd doesn't need to return the number given to it then, and you don't need to print the value given in. Change your method to this:

public static void evenorodd(int a) {
    if (a % 2 == 0) {
        System.out.println("Number Is Even");
    }
    else {
       System.out.println("Number Is Odd");
    }
}

And when you call it, don't put the method call inside a print statement.

Change this:

System.out.println(evenorodd(arr[0]));

to this:

evenorodd(arr[0])
