[CSC 204] Example of how to use the Scanner Class

[Andrew J. Pounds]

It has come to my attention that several of you had some difficulties 
using the Scanner class to take user input for your first programming 
assignment.  I am including a small "example" that should help you.  If 
you did not prompt for input in your Forecast.java program, then please 
fix it and resubmit it.


import java.util.Scanner;

public class ScannerExample{

// This is an example of how to input a double using the Scanner class

      public static void main(String argv[]){

      Scanner input = new Scanner(System.in);


      System.out.print("Enter x1: ");
      double x1  = input.nextDouble();   // Get grade

      System.out.println("You entered " + x1);
      }
}
