Can't get max and min number from file, java

I'm trying to get maximum and minimum number from the file, but it shows me the last number on the file, not the actual max and min. Could you please help?

import java.util.Scanner; import java.io.*;

public class CalculateNumbers {

static void calculation(String fileName) throws IOException {            int highest;      int lowest;            // Open the file      File file = new File(fileName);      Scanner inputFile = new Scanner(file);                      while (inputFile.hasNext()) {                            int num = inputFile.nextInt();                            highest = num;              lowest = num;                                          if (num > highest) {                                    highest = num;                                }                                          if (num < lowest) {                                    lowest = num;                                }                    }                                System.out.println("max num is " + highest);      System.out.println("min num is " + lowest);                  inputFile.close();  }  

public static void main(String[] args) throws IOException {

    Scanner keyboard = new Scanner (System.in);                  // Get the file name      System.out.print("Enter the name of the file: ");      String fileName = keyboard.nextLine();        calculation(fileName);
