I need help with JOption Panel!

Write a program that reads a string for a date in the format month / day / year and displays it
in the format day . month . year, which is a typical format used in Europe. For example, if the
input is 06/17/08, the output should be 17.06.08. Your program should use JOptionPane for
input and output.
Note - Your program should create an output string from the input string and should include
the following lines with appropriate Java statements at “…”

__________________________________________________ ___

import javax.swing.JOptionPane;
public class DateDisplayer
{
public static void main(String[] args)
{
String dateString = JOptionPane.showInputDialog(
"Enter a date in the format month/day/year .\n" +
"I will output the date in the format
day.month.year\n");
String day, month, year;

dateString = dateString.trim();
int delimiter = dateString.indexOf("/");
month = dateString.substring(…);
…
//System.out.println("index is " + delimiter);
//System.out.println("Month is " + month);
…
String rest = dateString.substring(…).trim();
//System.out.println("Rest is " + rest);
…
delimiter = rest.indexOf("/");
day = rest.substring(…);
…
//System.out.println("index is " + delimiter);
//System.out.println("day is " + day);
…
year = rest.substring(…).trim();
//System.out.println("year is " + year);
…
JOptionPane.showMessageDialog(null, dateString +
" converts to: " + day + "." + month + "." + year);
System.exit(0);
}
}
