Calculate Mode in Java

In statistics math, a mode is a value that occurs the highest numbers of time. For Example, assume a set of values 3, 5, 2, 7, 3. The mode of this value set is 3 as it appears more than any other number.

Algorithm

1.Take an integer set A of n values. 2.Count the occurrence of each integer value in A. 3.Display the value with the highest occurrence.

Example

Live Demo

public class Mode {    static int mode(int a[],int n) {       int maxValue = 0, maxCount = 0, i, j;       for (i = 0; i < n; ++i) {          int count = 0;          for (j = 0; j < n; ++j) {             if (a[j] == a[i])             ++count;          }          if (count > maxCount) {             maxCount = count;             maxValue = a[i];          }       }       return maxValue;    }    public static void main(String args[]){       int n = 5;       int a[] = {0,6,7,2,7};       System.out.println("Mode ::"+mode(a,n));    } }

Output

Mode ::7
