Question

NOTE: Use JOptionPane NOT Scanner Please

Write an application that allows a user to enter the names and birthdates of up to 10 friends. Continue to prompt the user for names and birthdates until the user enters the sentinel value ZZZ for a name or has entered 10 names, whichever comes first. When the user is finished entering names, produce a count of how many names were entered, and then display the names. In a loop, continuously ask the user to type one of the names and display the corresponding birthdate or an error message if the name has not been previously entered. The loop continues until the user enters ZZZ for a name. Save the application as BirthdayReminder.java.

import javax.swing.JOptionPane;

public class BirthdayReminder {
   public static void main(String[] args) {
       // Write your code here
       String sentinal = "ZZZ";
       final int size = 10;
       int count = 0;
       String name = "";
       String dateOfBirth = null;
      
       String[] names = new String[size];
       String[] birthdates = new String[size];
      
      
       while (!name.equals(sentinal) && count < 10) {
           name = JOptionPane.showInputDialog("Enter a name or enter ZZZ to quit: ");
           if(name.equalsIgnoreCase("ZZZ")) break;
           dateOfBirth = JOptionPane.showInputDialog("Enter birtdate: ");
           names[count] = name;
           birthdates[count] = dateOfBirth;
           count++;
       }
       System.out.println("Total number of names is: " + count);
       boolean repeat = true;
       boolean found = false;
       while (repeat) {
          
           name = JOptionPane.showInputDialog("Enter name to get birthday(or ZZZ to quit): ");
           if (name.equalsIgnoreCase(sentinal))
               break;
           else {
               for (int i = 0; i < count && !found; i++) {
                   if (names[i].equals(name)) {
                       found = true;
                       dateOfBirth = birthdates[i];

                   }
               }
               if (found)
                   System.out.println("The birthdate of " + name + " is " + dateOfBirth);
               else
                   System.out.println("Sorry, no entry for " + name);
           }
           found = false;
       }
   }
}
