I have a program that was working but isn't doing so now...

[Luke Forga]

would someone be so kind as to take a look at it and tell me what I have done to it. The code, shown below, are two classes.

------------------------------------------------------------------

 
// RectangleTest.java
 
import java.util.*;
 
public class RectangleTest
{
  public static void main(String[] args) 
  {
    Rectangle rect = null;
    
    Scanner scan = new Scanner(System.in);
    
    System.out.print("Enter the length of a rectangle: ");
    
    double length1 = scan.nextDouble();
    
    System.out.print("\nEnter the width of a rectangle: ");
    
    double width1 = scan.nextDouble();
    
    rect = new Rectangle(length1, width1);
    
    double area1 = rect.area();
    
    System.out.println("\nThe rectangles area is: " + area1);
    
    double perimeter1 = rect.perimeter();
    
    System.out.println("The rectangles perimeter is: " + perimeter1);
    
  } // end main
 
} // end Class

If you please could explain what's not working?
Doesn't compile, throw exception, wrong result, no result, ...?

[Layne Lund]

I agree. We need some more information. What exactly isn't working? Does the above code compile? If not, what errors do you get? If it compiles, what happens when it runs and how does it differ from what you expect? Is there a run-time error (i.e. an exception)? If so what message does it give?

Without this additional information, we can only guess at the intent of this code. Please provide more details so that we can answer your question. You should also take a look at some suggestions we have about How To Ask a Question at Java Ranch.

Once you fill in these details, we will be more than happy to help.

Keep Coding!

Understandable. Sorry about any confusion; however, I corrected the problem(s) and it is now working. Thanks again.
