Can someone please help me with a java assignment

Question

Hey all,
I have a favor to ask I have a program that I need for my java class, I have the just of it but I can't figure out the rest, can anybody please help me here is the directions:
Let's revisit fibonacci numbers, looking at it as a process involving iteration and arrays. Create an array fib[] of 101 elements. Make fib[0] = 0 and fib[1] = 1. Then, in an iterative process going from 2 to 100, compute fib[k]. These numbers get quite large; make it an array of double.
Then, let the user select a number (such as 7) and have the application display the corresponding finbonacci number (in this case 13). Do this as often as the user wants. If a number larger than 100 is provided, display an error message, but don't terminate the program.
Here is what I have so far: Please add on and feel free to return to me please, thank you:
// This is an application that transforms numbers into their Fibonacci number
import javax.swing.*;
public class Fibonacci {
     public static void main( String args[] ){
          int k; //simple counter
          int numSize; // how many numbers were entered
          int theNum; // the number entered by the user
          String response; //response of the user
          // define the array
          double fib[] = new double[ 101 ];
          // read in the numbers into an array
          k = 0;
          response = JOptionPane.showInputDialog( "Enter the first number" );
          theNum = Integer.parseInt( response );
          while (theNum > 0){
               if (theNum > 100)
          k++;
          fib [ 1 ] = 1;
          fib [ 2 ] = 1;
          response = JOptionPane.showInputDialog( "Enter the next number, negative to end" );
          theNum = Integer.parseInt( response );
     } // end while
     numSize = k;
// terminate
System.exit( 0 );
}// end main
} //end class Fibonacci

Try this program..Hope it helps
import javax.swing.*;
public class Fibonacci
     static double fib[];
     public Fibonacci()
          fib = new double[ 101 ];
          fib[0] = 0;
          fib[1] = 1;
          for(int i = 2; i < fib.length; i++)
               fib[i] = fib[i -1] + fib[i - 2];
     public static void main( String args[] )
          boolean end = true;
          String response = "";
          int theNum = 0;
          new Fibonacci();
          while(end)
               response = JOptionPane.showInputDialog( "Enter the number. 999 to end" );
               try
                    theNum = Integer.parseInt( response );
                    if(theNum == 999)
                         end = false;
                    else if(theNum <101)
                         String Message = "The Fibonacci number at "+ theNum + " is : "+ fib[theNum - 1];
                         JOptionPane.showMessageDialog(null, Message, "Fibonacci Number", JOptionPane.INFORMATION_MESSAGE);
                    else
                         JOptionPane.showMessageDialog(null, "Input should be less than 100", "Error", JOptionPane.ERROR_MESSAGE);
               catch(NumberFormatException ex)
                    JOptionPane.showMessageDialog(null, "Enter Numeric values", "Error", JOptionPane.ERROR_MESSAGE);
          System.exit(0);
     }// end main
} //end class FibonacciVish
