Maximum and minimum of an array using minimum number of comparisons using java code example

Example 1: Java program to find maximum and minimum number without using array

// Java program to find maximum and minimum number without using array
import java.util.Scanner;
public class MaximumMinimumWithoutArray
{
   public static void main(String[] args)
   {
      Scanner sc = new Scanner(System.in);
      System.out.println("Please enter total number: ");
      int numbers = sc.nextInt();
      int maximum = Integer.MIN_VALUE;
      int minimum = Integer.MAX_VALUE;
      System.out.println("Please enter " + numbers + " numbers.");
      for(int a = 0; a < numbers; a++)
      {
         int current = sc.nextInt();
         if(current > maximum)
         {
            maximum = current;
         }
         if(current < minimum)
         {
            minimum = current;
         }
      }
      System.out.println("largest of " + numbers + " numbers is: " + maximum);
      System.out.println("smallest of " + numbers + " numbers is: " + minimum);
      sc.close();
   }
}

Example 2: Find minimum and maximum values in a java array

// Find minimum and maximum values in a java array
public class MaxMinValueInArray
{
   public static void main(String[] args) 
   {
      int[] arrNumber = new int[]{50, 150, 250, 500, 160, 530};
      int maximum = maxNumber(arrNumber);
      System.out.println("Maximum value : " + maximum);
      // calling min function java
      int minimum = minNumber(arrNumber);
      System.out.println("Minimum value : " + minimum);
   }
   // java find max in array
   public static int maxNumber(int[] arr)
   {
      int maximumValue = arr[0];
      for(int a = 1; a < arr.length; a++)
      {
         if(arr[a] > maximumValue)
         {
            maximumValue = arr[a];
         }
      }
      return maximumValue;
   }
   // java min of array
   public static int minNumber(int[] arr)
   {
      int minimumValue = arr[0];
      // find minimum value in array java
      for(int a = 1; a < arr.length; a++)
      {
         if(arr[a] < minimumValue)
         {
            minimumValue = arr[a];
         }
      }
      return minimumValue;
   }
}
