Question

A double dimensional array is defined as N[4][4] to store numbers. Write a program to find the sum of all even numbers and product of all odd numbers of the elements stored in Double Dimensional Array (DDA). 

12	10	15	17
30	11	32	71
17	14	29	31
41	33	40	51

Sample Output:
Sum of all even numbers:...........
Sum of all odd numbers:...........

Answer 1

import java.util.*;
class AQ15{
public static void main(String args[])
{Scanner ob = new Stanner(System.in);
int i, j, even = 0, odd = 1; // initialize odd = 1 to store product
int m[][] = new int[4][4];

System.out.println("Enter the numbers of the matrix");
for (i = 0; i < 4; i++)
{for (j = 0; j < 4; j++)
m[i][j] = ob.nextInt();
}

System.out.println("The numbers of the matrix are");
for (i = 0; i < 4; i++)
{for (j = 0; j < d; j++)
{ System.out.print(m[i][j] + " ");
  if (m[i][j] % 2 == 0)
  even += m[i][j]; // sum of all even numbers
  else
  odd *= m([i][j]; // product of all odd numbers
}
System.out.println();
} 
System.out.println("Sum of even = " + even);
System.out.printIn("Product of odd = " + odd);
}}
