Troubles in converting roman to arabic..pls HELP!!!

Question

i have a code here in converting roman to arabic and vice versa. the roman to arabic method is properly giving the correct output, then the arabic to numeral methos is malfunction..what i want is the ROMAN to ARABIC only,,,but im confuse on what to delete/edit in this code...can u help me edit this??...pls??
here's the code...
import java.io.*;
public class Numerals
public static void main(String[] args) throws IOException
String input = null;
System.out.print("Enter either a Roman Numeral or number: ");
BufferedReader br2 = new BufferedReader(new InputStreamReader (System.in));
try {
input = br2.readLine();
catch (IOException e) {
e.printStackTrace();
System.exit( 1 ); // don't catch and just print - exit
try {
int number = Integer.parseInt( input );
System.out.println("number in roman numerals: " );
intToRoman(number);
catch(NumberFormatException nfe) {
System.out.println("roman numberal as a number: " + romanToInt(input));
//-------Convert Roman numeral to integer data---------
private static String romanToInt(String RN2)
RN2 = RN2.toUpperCase();
int [] RN = new int [RN2.length()];
for (int convert = 0; convert < RN2.length(); convert++)
if (RN2.charAt(convert) == 'M' || RN2.charAt(convert) == 'm')
RN[convert] = 1000;
else if (RN2.charAt(convert) == 'D' || RN2.charAt(convert) == 'd')
RN[convert] = 500;
else if (RN2.charAt(convert) == 'C' || RN2.charAt(convert) == 'c')
RN[convert] = 100;
else if (RN2.charAt(convert) == 'L' || RN2.charAt(convert) == 'l')
RN[convert] = 50;
else if (RN2.charAt(convert) == 'X' || RN2.charAt(convert) == 'x')
RN[convert] = 10;
else if (RN2.charAt(convert) == 'V' || RN2.charAt(convert) == 'v')
RN[convert] = 5;
else if (RN2.charAt(convert) == 'I' || RN2.charAt(convert) == 'i')
RN[convert] = 1;
else
RN[convert] = 0;
//--------Calculate the Roman Numeral---------
int y = 0;
int z = 0;
int Num = 0;
while (y < RN.length)
if ((y+1) != RN.length)
z = RN[y+1];
if (z > RN[y])
Num = Num + (z - RN[y]);
y++;
else
Num = Num + RN[y];
y++;
}//ends while
return(Integer.toString(Num));
}//ends romanToInt
// CODE TO TRANSLATE ROMAN NUMERAL TO NUMBER
private static void intToRoman(int Num2)
int r= 0;
String number = Integer.toString(Num2);
for ( r = 0; r < number.length(); r++)
//return(Integer.toString(number));
//System.out.println(Num3[r]);
} //ends intToRoman
}

ahhmm, i just want to delete the arabic to roman method...ahm, the program which i wanted is only the ROMAN to ARABIC...i want to dscard/disregard the ARABIC to ROMAN...
here's hte code:
import java.io.*;
public class Numerals
public static void main(String[] args) throws IOException
String input = null;
System.out.print("Enter either a Roman Numeral or number: ");
BufferedReader br2 = new BufferedReader(new InputStreamReader (System.in));
try {
input = br2.readLine();
catch (IOException e) {
e.printStackTrace();
System.exit( 1 ); // don't catch and just print - exit
try {
int number = Integer.parseInt( input );
System.out.println("number in roman numerals: " );
intToRoman(number);
catch(NumberFormatException nfe) {
System.out.println("roman numberal as a number: " + romanToInt(input));
//-------Convert Roman numeral to integer data---------
private static String romanToInt(String RN2)
RN2 = RN2.toUpperCase();
int [] RN = new int [RN2.length()];
for (int convert = 0; convert < RN2.length(); convert++)
if (RN2.charAt(convert) == 'M' || RN2.charAt(convert) == 'm')
RN[convert] = 1000;
else if (RN2.charAt(convert) == 'D' || RN2.charAt(convert) == 'd')

y++;
else
