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!

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).

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();

Phone Keypad Number As String

Sep 29, 2011

I'm trying to write a method that returns a number, given an uppercase letter as follows:

public static int getNumber(char uppercaseLetter)

The program is supposed to prompt the user to enter a phone number as a string. The input number may contain letters. The program translates a letter (upper- or lowercase) to a digit and leaves all other characters intact.

My code is below:

import java.util.*;
public class PhoneKeypad {
public static void main(String[] args){
System.out.print("Enter a string: ");
Scanner input = new Scanner(System.in);
String phNumber = input.next();

[Code] ....

I am getting these errors:
java.lang.ClassFormatError: Duplicate field name&signature in class file Chapter9/PhoneKeypad

Match Phone Number To 7 Letter Words

Jul 25, 2014

I got a phone number problem. I get a list of phone numbers and a word file containing words, how could I need to see if I could match the phone number to 7 letter words, then see if I can match the first 3 numbers to 3 letter words and then the last 4 numbers to 4 number words. I figured all that out so far. The last part of this assignment is to see if I could match a combination of words together to match the phone numbers.

Example:

JAVA Program That Will Generate A Random Phone Number

Mar 12, 2014

Instruction: You work for a telemarketing company and you are required to write a JAVA program that will generate a random phone number. (talk about a real-world application)

-The phone number should consist of 10 digits
-The first 3 are the area code and should not begin with 0, 8 or 9
-The second 3 digits should not be greater than 742 and not less than 100.
-The last 4 digits can be any digits
-Print the number using the following format: "(xxx)-xxx-xxxx", this way it will look like a real phone number (use decimal formatting)

User Enter 5 Digit Number And In Return List Each Number On Their Respective Lines

Sep 16, 2014

So I am currently writing my first assignment and have run into problems with my coding. The task was to have someone enter a 5 digit number and in return, I list each number on their respective lines. We also must create an error if a number other than 5 digits was entered. My problem is that when they enter a 1 or 2,3,4,6,7,8 digit number.. the error message occurs along with the rest of the messages (listing the numbers, etc). I want the program to end (or even re-ask to enter the numbers) if they incorrectly enter the data.

Random Phone Number Generator - Include Dashes In The Output

Apr 11, 2011

I've been working on a personal project again in Unit 3 of my text book and this time they want me to make a random phone number generator. Here's the actual directions:

"Write an application that creates and prints a random phone number of the form XXX-XXX-XXXX.

Include the dashes in the output.

Do not let the first three digits contain an 8 or 9 (but don't be more restrictive than that), and make sure that the second set of three digits is not greater than 742.

Think through the easiest way to construct the phone number. Each digit does not have to be determined separately."

With this assignment I came across 2 problems:

1. What I tried was that since the first 3 numbers have to be a random number with no 8's or 9's I tried doing this algorithm:

int first0, first1, first2, second, third, random0;
first0 = generator.nextInt (999);
random0 = generator.nextInt (8);
first1 = first0.replace('8', random0);
first2 = first1.replace('9' random0);

The problem is that Java won't allow me to generate random numbers this way. Are there any easier ways of generating numbers that doesn't contain specific number (such as 8 or 9 in this case?)

2. I was thinking about this throughout the whole project and what if I generate a number such as 27 (less than 3 or 4 digit number) rather than 3 or 4 digit numbers? How would it show 0027 or 027 instead of 27 for the phone numbers?

import java.util.Random;
public class pp0303 {
public static void main (String[] args){
Random generator = new Random();
int first0, first1, first2, second, third, random0;

[Code] ....

RESULTS:

Exception in thread "main" java.lang.Error: Unresolved compilation problems:
Cannot invoke replace(char, int) on the primitive type int
Cannot invoke replace(char) on the primitive type int
Syntax error on token "random0", delete this token

Java Lotto - Randomly Generate Five-digit Number And Prompts User To Enter Five-digit Number

Sep 25, 2014

1. Write a Java program that randomly generates a five-digit lottery number and prompts the user to enter a five-digit number. Each digit in the number is in the range between 0~9. The program should determine which prize the user wins according to the following rule:

- The user wins the first prize if the user input matches all five digits in the lottery number in exact order.
-The user wins the second prize if the user input matches any four digits in the lottery number in exact positions.
-The user wins the third prize if the user input matches any three digits in the lottery number in its exact position.
-The user wins the fourth prize if the user input matches any two digits in the lottery number in its exact position.

- The user wins the fifth prize if the user input matches any one digit in the lottery number in its exact position.here is my code. I have tried replacing the && statements with || and it always returns either case 1 or case default.

import java.util.Scanner;
import java.util.Random;
class Hw5 {
static int getPrize(int g1, int g2, int g3, int g4, int g5,
int u1, int u2, int u3, int u4, int u5) {

Replace Correct Number Into Letter?

Mar 8, 2014

I'm trying to figure out the correct way to replace number into letter. In this case, I need two steps.

First, convert letter to number. Second, restore number to word.

Words list: a = 1, b = 2, f = 6 and k = 11.

I have word: "baafk"

So, for first step, it must be: "211611"

Number "211611" must be converted to "baafk".

But, I failed at second step.

Code I've tried:

public class str_number {
public static void main(String[] args){
String word = "baafk";
String number = word.replace("a", "1").replace("b","2").replace("f","6").replace("k","11");
System.out.println(word);

[Code] .....

Result for converting to number: baafk = 211611 But, result for converting above number to letter: 211611 = bkfk

What do I miss here?

How to distinguish if 11 is for "aa" and for "k"? D

I have application written in rest with Jersey-Jackson for JSON processing. All the resources produce and consume JSON. Now, the problem is, it is a server intensive application and large number of request will be hitting the server with large JSON request object. Now, because of this reason, when the JSON object gets converted in to Java object with String fields in it mapping to JSON request values large number of string objects are getting created which is resulting in frequent GC.
