smallest and largest of the inputs


I was assigned to write a program that read a sequence of integer inputs and print -the smallest and largest of the inputs -and the number of even and odd inputs

I figured out the first part but am stumped on how I can get my program to display the largest and the smallest. This is my code so far. How can I get it to display the smallest input aswell?

public static void main(String args[])
{
      Scanner a = new Scanner (System.in);
      System.out.println("Enter inputs (This program calculates the largest input):");

      double largest = a.nextDouble();
      while (a.hasNextDouble())
      { 
          double input = a.nextDouble();
          if (input > largest)
          {
              largest = input;
          }
      }


      System.out.println(largest);
}

Solution

  • The simplest solution would be use something like Math.min and Math.max

    double largest = a.nextDouble();
    double smallest = largest;
    while (a.hasNextDouble()) {
        double input = a.nextDouble();
        largest = Math.max(largest, input);
        smallest = Math.min(smallest, input);
    }
