Question

JAVA

The mode of a list of numbers is the number listed most often. Write a program that takes 10 numbers as input and displays the mode of these numbers. Your program should use parallel arrays and a method that takes an array of numbers as a parameter and returns the value that appears most often in the array.

Answer 1

public class ArrayMode {

   public static int mode(int arr[]) {
       int maxValue = 0, maxCount = 0;

       for (int i = 0; i < arr.length; ++i) {
           int count = 0;
           for (int j = 0; j < arr.length; ++j) {
               if (arr[j] == arr[i])
                   ++count;
           }
           if (count > maxCount) {
               maxCount = count;
               maxValue = arr[i];
           }
       }

       return maxValue;
   }

   public static void main(String args[]) {
       int arr[] = { 9, 5, 3, 8, 5, 12, 19, 5, 11 };

       System.out.println("The set of numbers are: ");
       for (int i = 0; i < arr.length; i++)
           System.out.print(arr[i] + " ");

       System.out.println("\nThe mode of the set is: " + mode(arr));
   }
}
