help with program to convert integers to roman numerals

[akilbakari]

does anyone know where i can get source code to write a java 2 program GUI that converts integers to roman numerals? i would appreciate it.
my e-mail address is <<snip>>. by the way, here is my code:

import java.io.*;


public class Roman{


static final int values[]={1,5,10,50,100,500,1000};
static final char letters[]={'I','V','X','L','C','D','M'};


public static void main(String args[]) throws IOException,ArrayIndexOutOfBoundsException{


BufferedReader br=new BufferedReader(new InputStreamReader(System.in));


String numeral="";
int tempVal1=0;
int tempVal2=0;
int ans=0;
char ch1,ch2,ch3,ch4;



System.out.print("Enter a Roman number: ");
numeral=br.readLine();
numeral=numeral+" ";


for(int x=0;x<numeral.length();x++){
ch1=numeral.charAt(x);


if(ch1==' ')
break;


ch2=numeral.charAt(x+1);


tempVal1=findPos(ch1);
tempVal2=findPos(ch2);


if(x==0){
if(values[tempVal1]>values[tempVal2]){
ans+=values[tempVal1];
}
else if(values[tempVal2]>values[tempVal1]){
ans+=(values[tempVal2]-values[tempVal1]);
x+=1;
}
else if(values[tempVal1]==values[tempVal2]){
ans+=values[tempVal1];
ans+=values[tempVal2];
x+=1;
}
}
else{
if(ch2==' '){
ch3=numeral.charAt(numeral.length()-2);
ch4=numeral.charAt(numeral.length()-3);
int tempVal3=findPos(ch3);
int tempVal4=findPos(ch4);


if(values[tempVal3]<=values[tempVal4]){
ans+=values[tempVal3];
}
break;
}
else if(tempVal1<tempVal2){
ans+=(values[tempVal2]-values[tempVal1]);
x+=1;
}
else if(tempVal1>tempVal2){
ans+=values[tempVal1];


}


else if(tempVal1==tempVal2){
ans+=values[tempVal1];
ans+=values[tempVal2];
x++;
}
}


}


System.out.println("Integer value= "+ans);


}



public static int findPos(char ch){
for(int y=0;y<letters.length;y++){
if(ch==letters[y]){
return y;
}
}
return 1;


}
}
