Description

Sum the difference between each element in an array

Demo Code


class Difference {
  private int[] elements;
  public int maximumDifference;

  // parameterized constructor
  public Difference(int[] arr) {
    this.elements = arr;
  }//from w w  w  .j a v  a2  s  . c  o m

  public int computeDifference() {
    int max = 0;
    for (int i = 0; i < elements.length - 1; i++) {
      for (int j = i + 1; j < elements.length; j++) {
        int diffgap = Math.abs(elements[i] - elements[j]);
        if (diffgap > max) {
          max = diffgap;

        }
      }
    }
    maximumDifference = max;
    return maximumDifference;
  }
} // End of Difference class

public class Main {

  public static void main(String[] args) {

    int[] a = new int[10];
    for (int i = 0; i < a.length; i++) {
      a[i] = i * i;
    }

    Difference difference = new Difference(a);

    difference.computeDifference();

    System.out.print(difference.maximumDifference);
  }
}
