Java program to find differences between minimum and maximum numbers in an array

Program to find difference of minimum and maximum numbers of array in java

import java.util.Scanner;

class MinMaxInArray {
  //method to get maximum number 
  //from array elements
  int getMax(int[] inputArray) {
    int maxValue = inputArray[0];

    for (int i = 1; i < inputArray.length; i++) {
      if (inputArray[i] > maxValue) {
        maxValue = inputArray[i];
      }
    }
    return maxValue;
  }

  //method to get minimum number from array elements
  int getMin(int[] inputArray) {
    int minValue = inputArray[0];

    for (int i = 1; i < inputArray.length; i++) {
      if (inputArray[i] < minValue) {
        minValue = inputArray[i];
      }
    }
    return minValue;
  }
}

public class ExArrayDifference {
  public static void main(String[] args) {
    int n;

    // create object of scanner.
    Scanner sc = new Scanner(System.in);

    // you have to enter number here.
    System.out.print("Enter number of elements you wants to enter :");

    // read entered number and store it in "n".
    n = sc.nextInt();

    int arr[] = new int[n];

    for (int i = 0; i < arr.length; i++) {
      System.out.print("Enter [" + (i + 1) + "] element :");
      arr[i] = sc.nextInt();
    }

    MinMaxInArray mm = new MinMaxInArray();

    // print max , min , difference of array elements. 
    System.out.println("Maximum value is :" + mm.getMax(arr));
    System.out.println("Minimum value is :" + mm.getMin(arr));
    int Difference = mm.getMax(arr) - mm.getMin(arr);
    System.out.print("Difference between Minnimum and Maximum in array is : " + Difference);
  }
}

Output

    Enter number of elements you wants to enter :10
    Enter [1] element :25
    Enter [2] element :36
    Enter [3] element :74
    Enter [4] element :85
    Enter [5] element :964
    Enter [6] element :215
    Enter [7] element :36
    Enter [8] element :58
    Enter [9] element :98
    Enter [10] element :123
    Maximum value is :964
    Minimum value is :25
    Difference between Minnimum and Maximum in array is : 939
