java program to check sparse matrix code example

Example: Java program to check if it is a sparse matrix

import java.util;
public class SparseMatrix
{
   public static void main(String[] args)
   {
      Scanner sc = new Scanner(System.in);
      System.out.println("Please enter dimensions of sparse matrix: ");
      int x = sc.nextInt();
      int y = sc.nextInt();
      int[][] arrNumber = new int[x][y];
      int zeros = 0;
      System.out.println("Please enter elements of sparse matrix: ");
      for(int a = 0; a < x; a++)
      {
         for(int b = 0; b < y; b++)
         {
            arrNumber[a][b] = sc.nextInt();
            if(arrNumber[a][b] == 0)
            {
               zeros++;
            }
         }
      }	 
      if(zeros > (x * y) / 2)
      {
         System.out.println("Given matrix is sparse matrix.");
      }
      else
      {
         System.out.println("Given matrix is not a sparse matrix.");
      }	 
      sc.close();
   }
}
