Choose Option To Get Contact Details - Not Getting Output Expected
Feb 20, 2015
When I run my program and choose option 2 to get contact details I am expecting it to display as follows (First Name, Last Name): Contacts how have been entered:
0) John Doe
1) George Smith
2) Nancy Davis
Please enter the number corresponding to the contact you would like to view:
Instead for a personal contact it is displaying as follows:Contacts who have been entered:
0) Doe 1 F St. (last name, address)
Please enter the number corresponding to the contact you would like to view:
Instead for a business contact it is displaying as follows:Contacts who have been entered:
0) 1 F St. jd@gmail.com (address, email)
Please enter the number corresponding to the contact you would like to view:
Then when I enter the number to display the contact for personal it is returning me only first name and business is only returning me first and last name. It should be returning the full contact info that was put in during the add contact step. I thought I programmed everything properly but it isn't displaying what I want to seeMy code is listed below.

I have this Contact List program and im stuck on how to make my contact list show their different details. I don't know what to do , I want my program to be like this. What should I do next to make my every entry have different information then show on to the right side of the panel the information when i click the show details button .
I'm trying to create contact information as object and another object as parcel then calculate the shipping fee. Problem is I don't have a good understanding in implementing object type to my code. Attached are what I've done and I know that my constructor in my parcel class and contact class are probably wrong too but I don't know what to do with it.
//contact class public class Contact { private String Name; private String Address; private String City; private String State; private double Xco; private double Yco;
I am working on a contact list program with a GUI for a school project.I'm running into all kinds of issues when trying to update the JList in my GUI which displays the contacts.I think my issues are being caused by a lack of synchronization between the contact list that stores the data, and the contact list that is being displayed.I've tried all kinds of getters and setters, passing array indexes, passing array member objects etc.
General rundown of how I want the GUI/Code to work: When I select an object in the JLIst, the fields on the right should display that objects information.When the "Add Contact" button is created, a new blank contact should be created and added to the Contact List, and then displayed in the JList.When a field on the right side of the GUI is updated, the object in the contact list is updated simultaneously (using document listener), and therefore the JList would also be updated.
I have a question about arraylist objects.... I want to create an address book that will contain a persons information (name, phone, address, email..etc..). The first two snippets of code are from the same class ContactArrayList and the last one is from the class Contact. Do I need to create a separate arraylist for each data type? Is it possible to use a single arraylist to contain all the object (person) information and then be searched for using a GUI? I would also like to be able to access this data to be manipulated using a JFrame (add, edit, and search).
public class ContactArrayList<E> implements List<E> { public int size, capacity; E contact; private E[] contacts; public ContactArrayList() { size = 0; capacity = 20;
I'm working on a GUI Phonebook and need getting a button to work for deleting a contact. I identified the error I get in the Gui class where it says applyDeleteEntry(); on line 106 with comments. The entries are stored in a .txt file which is created for you.
Main class:
import javax.swing.*; import java.awt.*; public class Main{ public static void main(String args[]) throws Exception{ Phonebook mainPhonebook = new Phonebook(); Gui mainGui = new Gui();
I have one jsp page in which I have listed some service records fetched from Database. I have made one of the column, for eg. Service ID to be link, which should display all the details of that service when clicked. I want those details to be displayed in lightbox. I tried doing it but when any service ID link is clicked, it displays same(First Service in record) service details.How do I pass reference of that current service to lighbox effect.
I wrote a code from our text book for Pong. Im trying to figure out how to fill the ball with color. Im also wondering how to speed the ball up once there is contact with the paddle. The initial speed is ok but once contact is made with the paddle, it slows down. Makes it too easy to play. Here is my code so far. As far as the game goes, it works and is good. Just wanted to add a couple customizations.
Create a Java application that prompts the user to enter their personal details: First name, last name, gender, address, suburb, postcode, and phone number. Then the program displays all of your personal details to the screen as illustrated. Name the file PersonDetails.jav
package exe import java.util.*; public class Review2 { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.print("Enter your full name: "); String name = scanner.next();
[Code]...
If you cant tell straight away how i have stuffed up, what is happening is this;
When i am promoted to enter my name, 'John Smith'. The word 'John' would be stored in the name variable, while 'Smith' is stored under gender, so the next prompt is then 'Whats your address?'
So its only assigning one word per variable, now as far i understand, a string should not work that way. So where is my mistake?
I have small project to be implemented in Java, which, expected the management of a parking.
The project has a class abstract Vehicle, whence derive three classes: Car, Motorcycle, Heavy Vehicles; the cost estimated time for the 3 types of vehicles are: 2€ for Cars, 1€ for Motorcycle and 5€ for H.V.
In addition, in class Ticket will be stored the arrival time of the customer and the characteristics of his vehicle.
Finally, in the class Parking(which provides 80 places available), here it should be added the various types of vehicles.
Now, I though of using an Collection, as Set.. So that they can not, two Vheicle with same license plate.
I'm new to programming and java and I'm trying to understand how exactly this piece of code works and what exactly does. I'm trying to make my first GUI application and to read some person details from a file and then put the result in a Jlist.
private static final String SEPARATOR = ","; public static ArrayList<Speaker> getAllMembers() { ArrayList<Member> members = new ArrayList<Member>(); try { File file = new File(Resources.MEMBERS_TXT); Scanner fileReader = new Scanner(file, "utf-8"); String[] properties;
I need to choose the value of a list item in jsp. There are many employees in various departments and i need to choose that employees in department wise.
Example. I have two list items in jsp
1. Select dept_no,dept_name from departments 2. SElect emp_name from employees, departments where emp_dept_no=curr_dept_no and curr_dept_no = dept_no
These two are the list items. When i choose the department from the first list item i need to display the employees in that particular department in the second list.
I have good knowledge of servlet,jsp. I've also worked on mvc pattern and now looking to learn a web framework but i'm not sure which to choose between spring mvc OR struts.Should i first do struts and then go for spring or can i choose spring directly?
I am using eclipse for this project. Every time I run this program the choose method will always choose 0. Ignore the Sleep.sleep() method, there is another class in the program that performs it.
import java.util.Scanner; public class gamestart { public static int num; public static String name; public static String diff; public static String choice;
I recently wrote a simple recursive program that chooses K objects out of N (I was asked to use the variables N choose the R, however) total objects. Here is the code:
int n = 0; int r = 0; //the total number of objects defaults to 0 String nChoice = JOptionPane.showInputDialog(null, "How many objects are there to choose from?"); String rChoice = JOptionPane.showInputDialog(null, "How many object are to be chosen from this group?"); try { n = Integer.parseInt(nChoice);
[Code] ....
It works fine, however in my class we were given two different formula to implement into our code. I used the one above, obviously. However, the second formula we were given was:
C(n,R) = n! -------(R!(n-R)!)
I had to get the spacing right.
How do I read this formula? How could it be implemented? What are the benefits (if there are any) from using one method over the other? Which method of calculating N choose K (or, in my case, N choose R) would be more widely accepted?
I want to display product details such as product image, name, price in a one cell of a table tag on jsp page. There should be multiple rows and 3 cells per row in the required output.i have written the following code:
This code displays all cells in only one row. I used colspan but its not working...I have attached the snapshot of above code output and required output
i am trying to do a program captures keystroke and mouseclick from user in a textarea and insert the details intoa text file using java. Mainly such as delay between keys, no. of times backspace being pressed, alt tab press and copy paste mouse click.
I will try to explain what i want to code , a HiLo game where the user can choose up to 3 different levels(1-10, 1-100, 1-1000) with these 3 methods
public static void main(String[] args) {...} public static int playGame(int maxNumber) {...} public static void giveResponse(int answer, int guess) {...}
with no Random , i will use the:
int number = (int)(Math.random() * max) +1; to generate numbers
I have tried so many times , but i don't get it ....
My code so far :
import java.util.Scanner; public class HL{ public static void main(String[] args ){ Scanner s = new Scanner(System.in);
I am trying to create a slightly modified cash register. The user will enter the amount of the item, the payment received, calculate the change/refund, and then allow the user to choose the preferred bills.
import java.util.Scanner; public class Register { private static Scanner input; public static void main(String[] args) { input = new Scanner(System.in); System.out.println("*****CASH REGISTER*****" ); System.out.print("Item Amount: " ); int amount = input.nextInt();
[Code] ....
I will try to clarify the code, to make things a little easier to interpret. in the refund method, I have set up a 2-d array to exist and function as an excel sheet. The refund amount is passed to the method and compared to each bill of the array. Once the refund is determined to be greater than a bill, the user is prompted to enter the preferred bill type. This is where my problem is...I would like the program to then calculate the number of bills and keep a tally of those bills in the 2nd column and then determine the new refund amount at which point the user will be prompted again to determine the desired bill.
Then print out the array of bills that are not equal to 0.
the problem which im facing when executing jar file is it is not working same as when i run file using the IDE.When run jar file, it won't open the new frame even the user and pass combination correct.But when i'm compiling using the IDE, it works as charm. The main menu popped up after i logged in.I've tried Clean and Build and it's not working too.
When do you get the error <identifier> expected? I've written a small application where input is accepted by a textfield and based on some condition a dialog should be displayed saying "invalid i/p". But am not able to correct ths particular error ....
I am trying to get a scrollPane working correctly, but not having any luck. The picture drawn in the center panel is quite large and goes off the screen. I visited URL... but I am missing something vital. Both tracks show, but there is no knob to do the scrolling.
