This is a question for Schillj HELP!!!!

Question

Last week you helped me with this code
unfortunately I am so novice that I cant get it to work anywhere I understand it completely I just dont know where to put it in java code. Unfortutnately the logic is the easy part for me right now. I have researched everything that I dont understand in the code and understand it now. but the code and syntax make very little sense at this point.
I have a program that allows to input a number and then hit a calculate button that would obviously run the number through this code but how do I implement this or place insert it into a program. HELP!!!!
final static int MAXVALUES = 7;// 1, 5, 10, 50, 100, 500, 1000// is there a 5000 symbol and beyond?
final static String[] Symbols ={"I", "V", "X", "L", "C", "D", "M"}; 
String toRoman(int input) 
  if(input < 0)    
  throw new IllegalArgumentException("Error! value less  than 0");  
if(input > 3999)     
throw new IllegalArgumentException("Error! value exceeded 3999");   
int[] values = new int[MAXVALUES];  
int scale = 1;  
int mult = 5;  
for(int loop = 0; loop < values.length; loop++)  
   values[loop] = ( input % (scale * mult)) / scale;       scale *= mult;    
mult = (mult == 5 ? 2 : 5);    }  
// values are now set as per my last post   
// the fives, fifties, five hundreds values can only be 0 or 1   
StringBuffer buf = new StringBuffer("");  
// now evaluate string   
for(int loop = 0; loop < values.length; loop++)  
   switch(values[loop])    
    case 4:       
  // this can only happen on a 1s, 10s, 100s, etc      
   if(loop != values.length-1)      
if(values[loop+1] == 1)          
     // special case, this does "IX", "XC", etc                  buf.append(Symbols[loop+2]).append(Symbols[loop]);          
   // now increment loop as we have taken care of the next symbol             
loop++;          
   else          
// this does "IV", "XL", etc.           
  buf.append(Symbols[loop+1]).append(Symbols[loop]);          
break;      
case 3:
// this does "III", "XXX", etc        
buf.append(Symbols[loop]);       
case 2: // this does "II", "XX", etc        
buf.append(Symbols[loop]);      
case 1: // this does "I", "X", etc        
buf.append(Symbols[loop]);         
break;       
case 0:       
  break;      }    }
    return buf.reverse().toString();  }

I am sorry I am really not trying to scam anyone. here is my code.
package newroman;
* Title:        newRoman
* Description:
* Copyright:    Copyright (c) 2001
* Company:
* @author Matt Wilson
* @version 1.0
public class NewRoman {
   private int vNumber;
   public NewRoman()
   public NewRoman ( String roman, int number)
   this.setNumber(number);
   public int getNumber()
      return vNumber;
   public void setNumber ( int number )
      if ( number <= 0 )
      vNumber = number;
   public String getRoman()
      String strNumber = new String( String.valueOf(this.getNumber()));
      String romNum = new String();
      //find blank position in number
      int blankPos = strNumber.indexOf(" ");
      // get the number out of the string
      int stdNum = Integer.parseInt( strNumber.substring(0,blankPos));
      // determine thousands
      if ( stdNum >= 1000)
         romNum = threeDigits (stdNum / 1000);
      // determine hundreds, tens and ones
      romNum = romNum + threeDigits ( stdNum % 1000);
      return romNum;
   private String threeDigits ( int roman )
       String onesVal[] = {"", "I", "II", "III", "IV", "V", "VI", "VII", "VIII",
                          "IX", "X"};
       String tensVal[] = {"", "XX", "XXX", "XL", "L", "LX", "LXX", "LXXX", "XC"};
       String hunVal[] = {"C", "CC", "CCC", "CCCC", "D", "DC", "DCC", "DCCC", "CM"};
       String thouVal[] = {"M", "MM", "MMM", "MMMM"};
       int thouAmount = roman / 1000;
       int rem = roman % 1000;
       String romNum = new String();
       if (thouAmount > 0 )
          romNum = thouVal[thouAmount];
       int hunAmount = roman / 100;
       if (hunAmount > 0);
          romNum = hunVal[hunAmount];
       int tensAmount = rem / 10;
       if ( rem < 20 )
          romNum = romNum + onesVal[tensAmount];
       else
         // int tensAmount = rem / 10;
          int onesAmount = rem % 10;
          romNum = romNum + tensVal[tensAmount] + onesVal[onesAmount];
      return romNum;
}If anyone can give me any pointers on how to make it better especially with jbuilder. I just want to learn it is my only goal not to scam anyone anywhere.
thanks!
