java

what is mising from my code

i need the outpot to be like this (

but i have this (The sum of pro is 10)

this is my coed

import java.util.Scanner;
public class Calculation
{

   public static void main(String[] args)
   {
Scanner scan = new Scanner (System.in);
int [] pro = new int [9];
       int i;
       for (i = 0; i < pro.length; i++)
       {
           pro [i] = scan.nextInt();
       }
       int sum = 0;      
       for ( i = 0; i < pro.length; i++)
           if (i%2 == 0)
           {
               sum+= pro[i];
           }
           else if (i%1 == 0)
           {
               sum-= pro[i];
           }
      
System.out.println("The sum of pro is "+ "" + sum);
}   
}

Explanation / Answer

import java.util.Scanner;

public class Calculation {
   public static void main(String[] args) {
       Scanner scan = new Scanner(System.in);
       int[] pro = new int[10];
       int i;
       for (i = 0; i < pro.length; i++) {
           pro[i] = scan.nextInt();
       }
       int sum = 0;
       System.out.print("The sequence is ");
       for (i = 0; i < pro.length; i++) {
           if (i % 2 == 0) {
               if (i == 0)
                   System.out.print(pro[i]);
               else
                   System.out.print("+" + pro[i]);
               sum += pro[i];
           } else if (i % 2 == 1) {

               System.out.print("-" + pro[i]);
               sum -= pro[i];

           }
       }
       System.out.println("=" + sum);
       System.out.println("The sum of pro is " + "" + sum);
   }
}

OUTPUT:

1 1 1 1 1 1 1 1 1 1
The sequence is 1-1+1-1+1-1+1-1+1-1=0
The sum of pro is 0

NOTE:

make the array size as 10
