Build Address Book?

Feb 2, 2015

I am trying to build an address book, and I started from what i know how to do.

public class Persona {
String nome;
String indirizzo;
int cellulare;
public Persona(String nom, String ind, int cel) {
nome = nom;
indirizzo = ind;
cellulare = cel;

[code].....

Now I would like the program to take a string I insert on command line (for example java Cerca"Robert Baratheon") and compare it to the nome field of every Persona in the address book.

Address Book - Unique Object Names

Aug 22, 2014

I found out what my next java class project is, and i am trying to get a head start on it. It is a simple address book. it needs to have 4 choices that get cycled through until quit is chosen:

1. add business contact
2. add personal contact
3. display contacts
4. quit

I have made an abstract contact class with a personal subclass and business subclass(all 3 are required). they have all been made, with set/get methods(the wonders of encapsulation and polymorphism have finally hit home!). The main program needs to add a new subclass object when chosen, and it needs to accept and store contacts by type

So, i am figuring 2 object arraylists for business/personal.

My question is: how do you create an object without having a name for it already programmed? Does it even need to have a unique name, since it would be stored in a seperate index and/or arraylist?

Contact contact = new Contact();
this.firstname = "Be";
this.secondname ="Ginner";
this.phonenumber = "921-456-0102";
personalArray.add (contact);

Then cycle through, changing the properties, and add again to personalArray?

ArrayList - Contact Information / Address Book

Jul 5, 2014

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;

Create Address Book Complete With Menu System

Oct 19, 2014

So for the last few weeks I have been working on a Java project for school. I see the light at the end of the tunnel, but I have run into some speed bumps with my main class. It was working fine, but I was pulling an all night and I deleted some of my code by mistake.Now I am not seeing what is exactly wrong. Anyways, the project was to create an address book complete with a menu system.

Here are all of my classes:

import java.util.ArrayList;
/**
* A model of an address book which keeps track of contacts.
* An address book object should keep track of the concept of a current contact (think index).
* You must use an ArrayList for your implementation.
*/
public class AddressBook {
Contact contact = new Contact();

Web Services :: Telephone Book - Enter Phone Number / Correct Person With Name And Address Should Appear

Nov 30, 2014

Applications: Netbeans (8.0.1), Apache Tomcat

My Aim: Creation of a telephone book

How should it work:

I have a Database with Data of people (name, adress, phone number).

If a user enters a phone number (CLIENT) -> the correct person with the name and adress should appear.

I build up the infrastructure and now I'm at the point that I have to create a Webmethod for it. I just worked on projects like addition of two integers, hello "name", ... I think this example now is harder, BUT i can learn a lot!

Java Code Can Get At The Address Of Some Object Or Other Datum

Mar 17, 2015

I wanted to ask is there any way that Java code can get at the address of some object or other datum? I've found this useful a few time with certain high performance C# libraries that I've developed.

Also does Java have the equivalent of C#'s "fixed" buffers? which are inline contiguous arrays of primitives (like Chars or Ints etc).

Validate IP Address With Java Regular Expression

Jan 23, 2015

I am trying to implement an example (Book* : Java SE 7 ..By S G Ganesh) for validating an IP address but it fails to validate a valid IP addresses. I found another example on the internet(**) and it works super fine, no problem at all. I edited the code (the one I got from internet) into the exact format like book and it still works super but i don't understand why the books' example doesn't work though both look exactly the same now ,further more, how can i compare String x and y for equality?

public class TestClass {
void validateIP(String ipStr) {
String one = "((25[0-5]|2[0-4]d|[01]?dd?)(.)){3}(25[0-5]|2[0-4]d|[01]?dd?)"; //copied from internet and edited
String two = "((25[0–5]|2[0–4]d|[01]?dd?)(.)){3}(25[0–5]|2[0–4]d|[01]?dd?)"; // copied from book
String x = "((25[0-5]|2[0-4]d|[01]?dd?)(.))";
String y ="((25[0–5]|2[0–4]d|[01]?dd?)(.))";

[Code] ....

Java IP Address Program - Check If It Is Public Or Private

Feb 2, 2015

I am doing an assignment for a college class. We are asked to get user input and decide if it is a valid IP address and then check what class the address is and if it is a public or private address.

So far, I can get the input, and check to see if the numbers are in a valid range. I can also display the IP address to the user. I am having an issue figuring out how to get the program to check the classes and whether they are public or private.

import javax.swing.JOptionPane;
/**
This program will take user input and calculate whether it is a valid IP address and the class that it belongs to.
*/

public class shortONE_1
{
public static void main(String[] args)
{
//Variables
final int MIN_OC = 1; //Minimum number accepted
final int MAX_OC = 255; //Maximum number accepted
final int MIN_A = 1; //Min number for class A
final int MAX_A = 127; //Max number for class A

Remove Book And PrintAuthorBook Methods Won't Work

Why my borrowBook, returnBook, getBookIndex, remove book and printAuthorBook methods wont work. They all have a parameter that is a string and Im guessing its a common problem in all the methods. I think all my code for Book class is right. Iv attached the two classes. I also attached the test library which tests the two classes.

public class Book
{
// The fields:
private String author;
private String title;
public int pages;
public String refNumber;
public int numBorrowings;
boolean available;
// add more fields here

Program With Ability To Book Appointments For A Number Of Different Services

Sep 30, 2014

I am creating an apointment application. This programm will have the ability to book apointments for a number of different services, such as doctors, hairdressers, teachers etc for a number of cities.

These information will be placed on a combo box and ideally i would like to provide only the options available acording to the choices made so far.

So, for example we have
A Pediatric in London
A Vet in London
A Sergeon in Berlin
A Barber in Berlin
A Heardresser in Rome
A Programmer teacher in London
An English teacher in Rome

My thinking is that the user choses the city, for example London, then there will be a type of service combo box. In this case (of London) it will hold Doctors and Teachers. If Doctors is chosen, the next field will hold the available Medical specialty, i.e. Pediatrics and Vets and according to that choice the apropriate doctor will pop up.

My problem is not how to programm that. i havent got there yet.

My problem is how to design it! I am thinking that each individual will be an object. each having the same fields, city, type of service etc. But in such a way i am not sure how i can manage to get all the appropriate information in order to poppulate the combo boxes.

I would have to search all the objects for each combo box? From a rough testing i did, i think i could easily get all the individuals that resign in London, but that would give me two records for the doctors(for example).

HashMap - Searching Library Program By Book Index

Feb 9, 2014

I'm trying to search a library program by book index and running into some trouble with my HashMap. Here's the code in question:

Java Code:

public String searchByBookIndex(int input) {
NumberFormat fmt = NumberFormat.getCurrencyInstance();
Map<Integer, Book> bookMap = new HashMap<>();
for (int i = 0; i < author.booksByAuthor.size(); i++) {
bookMap.put(author.booksByAuthor.get(i).getBookIndex(), book);

[Code] ....

The search itself works fine; however, the problem is that the values of everything in the HashMap are overwritten by the last book entry. For example, let's say there are four books (index in parenthesis):

The Book (1), A Wonderful Book (2), A Great Book (3), A Bad Book (4).

Once the code above iterates, the HashMap out is this (via println):

1 = A Bad Book, 2 = A Bad Book, 3 = A Bad Book, 4 = A Bad Book.

What's causing this?

Use FileInputStream To Open A File That Contains Name Of User Favorite Book And Then Displays It

Aug 9, 2014

I'm working on a problem where I have to use the FileInputStream to opens a file that contains the name of a user's favorite book and then displays it.

If the file doesn't exist, then I prompt for the book title and write it to the file using FileOutputStream. This is what I have so far but I'm lost because if I put a file that exists in line 8 then it closes, but if I don't and the user puts their favorite book nothing happens. Or, as far as I can tell nothing does.

import java.io.*;
class DisplayBook {
public static void main(String[] args)

DOM XML Parsing - Fetch Only Book Name Attribute / Return Array Of URL Nodes Value Within It

Feb 22, 2014

Sample XML:

XML Code:

<Books>
<Book id="1" Name="C#">
<URL>http://localhost/download/M1.xml</URL>
</Book>

<Book id="2" Name="Oracle">
<URL>http://localhost/download/M2.xml</URL>
</Book>

<Book id="3" Name="Archius">
<URL>http://localhost/download/M3.xml</URL>
<URL>http://localhost/download/M4.xml</URL>
</Book>
</Books> mh_sh_highlight_all('xml');

I have to fetch only the book name attribute and use it for display .However say for example ,I have got the list of Books ie(C#,Oracle,Archius) ,passing this value to a method should return me an array of URL nodes value within it.

The idea is to display the book names in a list and then on user selection , corresponding URL needs to be fetched.

Was able to get the loop for traversing the nodes

[java=code]
NodeList nodeList = document.getDocumentElement().getElementsByTagName ("Book");
for (int i = 0; i < nodeList.getLength(); i++) {...
[java=code]

So

a) Display the BookNames

b) Get the corresponding URL's for the particular book if I pass the Bookname

Get Value From Address And Save It In Variable?

Mar 15, 2014

I just started using java because i want to create a simple web service that will take some values from within a url and save those values in variables.

To be more specific:

For my project I use the Spring Tool Suite.

I want to be able to enter a URL in a browser.. something like "localhost:8080/test?name=Root". When I hit Enter a page will be displayed showing "Hello Root" if the name in the URL is Root or "Hello User" for any other name.

I accomplish that with this code:

Java Code:
String UserName = "Empty";
@RequestMapping("/test")
public @ResponseBody String username(@RequestParam(value="name")String name){
if (name == "Root")
UserName = "Hello" + name;
else
UserName = "Hello User";
return UserName;
} mh_sh_highlight_all('java');

My problem is that it if I enter Root as a name in the URL it doesn't recognize it and it shows "Hello User".

I tried Java Code: << if (name.toString() == "Root") mh_sh_highlight_all('java'); but no luck.

How exactly I should reform this code in order to make it work?

How To Get The Actual Computer IP Address

Jan 31, 2014

I wrote a Chess game that uses socket to connect to another computer, and allow player vs player and player vs computer game sessions.

However, there is a problem which I noticed.

When you get the IP address of the computer in which the program is running, you are not getting the computer's actual IP, you are getting the Router's IP.

Is there a way to get around this.

So the problem is that when I go to another computer, located in a different house or lets say from my school, the program cannot connect back to my home IP, because it uses the router's ip, not the computer's ip I am running the server program.

Is there a way to get the Computer's IP, not the router's ip when summoning or invoking the get IP address method from the socket class?

When I say that the socket class is acquiring the router's ip, well that's done without my interfering...I don't know why it does that, it is somehow recognizing the router and not the computer.

The thing is that the server program is written that any client program is able to connect to the home server.

But when I run the program from a different location other than the current home, the sockets don't connect because it is somehow recognizing the router's ip not the computer's ip.
