title: How can the minimum and maximum of a list of integers in a .text file be determined?
body: <p>My objective is to read a .text file filled with an unknown amount of integers and find the sum/average/min/and max. 
  I have it down to finding the sum and average, I just need help finding the min and max from a .text file. Here is what I have so far.</p>
  
  <pre><code>public static void main(String[] args)
  {
      Scanner file = null; //initializes file to empty
      int cnt=0;
      int sum = 0;
      double average;
      try
      {
          //attempt to open file.
          file = new Scanner(new FileInputStream("pd06.txt"));
      }
      catch (FileNotFoundException e)
      {
          System.out.println("File Not found. Error 404");
          System.exit(2);
      }
  
      while(file.hasNextInt())
      {
  
          sum+=file.nextInt();//sums all numbers within the file 
          cnt++;              // counts all numbers in file.      
                              // Used in average. 
      }
      average = (double)sum / cnt; //Average
  
      System.out.println("There are "+cnt+" numbers in "
              + "the file.");
      System.out.println("The sum of which is "+sum);
      System.out.printf("The average of all %d numbers "
              + "is %.2f\n",cnt ,average);
  }
