How to compare and edit Resource bundle file using java programe

Question

Hi All
I have two resource bundle with key, value and some comments. I need to write a java code to compare both of the values of the keys and if the values are different then i want to replace the second value with the first value.
Its a programe which will udpate the second file with the first file values.
I tried using Properties class but it didnt worked because when i am saving the file using store method it removes all the comments and the order of text also got disturbed.
How I need to do this any help appriciated.
Please elt me know if someone needs more info.
Thanks in advance.

Let's assume the ini file is a mapping type storage (key=value) so lets use Properties object. (works with java 1.4 & up)
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.Properties;
public class Test {
     private static Properties props;
     public static void main(String[] args) throws IOException {
          File file = new File("test.ini");//This is out ini file
          props = new Properties();//Create the properties object
          read(file);//Read the ini file
          //Once we've populated the Properties object. set/add a property using the setProperty() method.
          props.setProperty("testing", "value");
          write(file);//Write to ini file
     public static void read(File file) throws IOException {
          FileInputStream fis = new FileInputStream(file);//Create a FileInputStream
          props.load(fis);//load the ini to the Properties file
          fis.close();//close
     public static void write(File file) throws IOException {
          FileOutputStream fos = new FileOutputStream(file);//Create a FileOutputStream
          props.store(fos, "");//write the Properties object values to our ini file
          fos.close();//close
}
