my friend is having a hard time coding an address book using JAVA PL. i want to help her but unfortunately, i dont know anything about that language. so i told her to give the code to me and i'll try to ask around.

Quote:

import javax.swing.*;

public class AddressBook {
public AddressBook() {
}

public static void main(String[] args) {

int addEntry = 0;
int deleteEntry = 0;
int viewEntry = 0;
int exit = 0;

final int MAX_SIZE = 3;
int[] arrOptions = new int[MAX_SIZE];

int userInput = 0;
int flag = 0;

try{
do{
userInput = Integer.parseInt(JOptionPane.showInputDialog("Ente r what you would like to do: \n[0] ==> Add Entry \n[1] ==> Delete Entry \n[2] ==> View all entry \n[3] ==> Exit"));

for (int i = 0; i < arrOptions.length; i++) {
if (userInput == i){
}
}

if (userInput == 0){

String temp = " ";

AddressBookEntry name = new AddressBookEntry();
AddressBookEntry address = new AddressBookEntry();
AddressBookEntry telNum = new AddressBookEntry();
AddressBookEntry eAdd = new AddressBookEntry();

int x = 0;

try{
do{

x++;
if (x<=3){
name.setName(JOptionPane.showInputDialog("Enter a Name"));
address.setAddress(JOptionPane.showInputDialog("En ter Address"));
telNum.setTelNum(Integer.parseInt(JOptionPane.show InputDialog("Enter Tel. Number")));
eAdd.setEAdd(JOptionPane.showInputDialog("Enter E-mail Address"));

temp = temp + "\nEntry number "+x+
"\nName:\t\t\t"+name.getName()+
"\nAddress:\t\t"+address.getAddress()+
"\nTelephone Number:\t"+telNum.getTelNum()+
"\nE-mail Address:\t\t"+eAdd.getEAdd()+"\n";

}

flag = JOptionPane.showConfirmDialog(null, "Would you like to continue?");
}while (flag==0);
if(flag == 1){
userInput = Integer.parseInt(JOptionPane.showInputDialog("Ente r what you would like to do: \n[0] ==> Add Entry \n[1] ==> Delete Entry \n[2] ==> View all entry \n[3] ==> Exit"));

}

}catch(Exception e) {
JOptionPane.showMessageDialog(null, "Error!!!");
}
JOptionPane.showMessageDialog(null, temp);

}
if (userInput == 1){
deleteEntry++;
JOptionPane.showMessageDialog(null, "Please delete add an entry");
}
if (userInput == 2){

}
if (userInput == 3){
System.exit(0);
}

} while (flag == 0);
} catch (Exception e) {
JOptionPane.showMessageDialog(null, "Error!");
}
}
}

Hello ^Son_Gokou08 and welcome to the Java Programming Forums.

What problems is your friend having with the code? Is she working to any kind of specifications?

oopps. sorry for my blunder, i forgot to include this in my post...

Quote:

Create a class AddressBook that can contain 100 entries of AddressBookEntry objects (use the class you created in the first exercise). You should provide the following methods for the address book.

1. Add entry

2. Delete entry

3. View all entries

she's having problem with number 2 (delete entry).
