Question

Define a class to accept values in integer array of size 10. Find sum of one digit number and sum of two digit numbers entered. Display them separately.

Example: Input: a[ ] = {2, 12, 4, 9, 18, 25; 3, 32, 20, 1}
Output: Sum of one digit numbers : 2 + 4 + 9 + 3 + 1 = 19
Sum of two disit numbers: 12 + 18 + 25 + 32 + 20 = 107

Answer 1

import java.util.*;
public class Sumnum {
     public static void main(String[] args) {
          int array[] = new int[10]; 
          int s1=0,s2=0;
          Scanner sc=new Scanner(System.in); 
          System.out.println("Enter 10 numbers :");
          for(int i=0;i<10;i++)
               array[i]=sc.nextInt();
          for( int i=0;i<10;i++)
                if ((array[i]>=0 && array[i]<=9))
                     s1 +=array[i];
                else if ((array[i]>=10 && array[i]<=99))
                     s2+=array[i];
         System.out.println("Sum of 1 digit numbers :"+s1);
         System.out.println("Sum of 2 digit numbers :"+s2);
     }
}
