I am trying to validate the phone number with a method called isValidAddress and whenever it gets to that line of code in the while loop I get a lot of red line java exceptions. I am referring to lines 130-138

if (TxtMobile.getText().length() < 11) {
rooms.setVisible(false);
JOptionPane.showMessageDialog(getRootPane(), "Mobile number should be 11 numbers long", "Mobile Error", JOptionPane.ERROR_MESSAGE);
TxtMobile.requestFocus();
}
else if (TxtMobile.getText().length() == 11) {
rooms.setVisible(true);
}
No compilation errors but code doesnt seem to be working. IF mobile number input is less than 11 numbers an error message dialog appears to alert the user then is supposed to focus on the text box in question. But instead after clicking the ok on the dialog box, the next rooms form shows up even though ive set that to setVisible(false).
I had to write a program for class using the method definition "public static char getNumber(char upperCaseLetter)" It compiles and runs but wont print out my final answer.
import java.util.Scanner;
public class Phone_0104730303 {
public static char getNumber(char upperCaseLetter)
{
char return_val = 0;
[Code].....
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:

I am new to java, and now i have an assignment. I have to parse a phone number like this--> (656) 345 6544 to 6563456544. I've writen the following code that works great with a while loop. Now i would like to know how can i make it work with a for loop.
and the code is
import java.io.*;
public class Tema
{
public static String removeChar(String str, int i) {
String first= str.substring(0,i);
[Code] .....
import java.util.*;
public class PhoneNumber {
private int areacode;
private int number;
private int ext;
PhoneNumber() {

I just can't seem to get it completely correct.
PhoneNumber.java:35: error: incompatible types: int cannot be converted to String
areacode = Integer.parseInt(str[0]);

PhoneNumber.java:38: error: cannot find symbol

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:
531 3259

I'm trying to output a ten digit phone number as a string on one file, and write another program to write it as a long because I don't know what value I need to use in order to get the code to run properly on either one.
View Replies View RelatedInstruction: 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)
by this : Generating Random Numbers
Using arithmetic operations
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;

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!
I have to validate security number based on tHIS REQUEST
If the SECURITYNNUBER IS INVALID UNDER THE SECURITYNUMBER attribute,it must reject(Date & algorith). To override the normal validation,the subject must contain INVALIDSECURITYNUMBER. The incorrect ID number must still reflect in the SECURITYNUMBER attribute.
THE FIRST 6 DIGIT IS DATE
EXAMPLE 7701205334086
public boolean val_SECURITYNUMBER()
{
boolean flag = true;
String u_Securtynr = transactionFile.getS_securtynumber();
// 1. Invalid securty number if completed

I have a question with this gui project I am building, I have gotten the code to work in very basic forms such as the main part of calculations and etc. But now I am in the phase of validation to make sure the textboxes aren't empty and are in the correct format. I have done alot research already. I would like to use a Joptionpane to warn the user of an invalid entry. But I have tried many different methods and I can't seem to get them to work.

I was wondering if there was a way to check/view messages from my phone. I'm trying to create a program that will be able either read messages from my phone, or reply to them. I'm trying to get this to work for a Window Phone, but I don't know if there is a difference between doing it on a Windows Phone or Android. Most of the topics that somewhat relate to what I'm doing are all Android based.
I've looked at AT Commands, SMS Gateways, but I'm still not sure if it's entirely possible.
I need a phonebook that allows the user to input up to 100 numbers but stop when they want to. I have the code for the array and input and output. I thought I had the do...while loop correct for asking the user if they want to input another name but its not working, even when you input "N" it still keeps going. Here's my code.

This particular program is supposed to prompt the user to input either an uppercase or lowercase Y to process a phone number, they are then prompted to enter the character representation of a phone number (like CALL HOME would be 225-5466), this repeats until the user enters something other than the letter Y. All of the words entered are to be stored into a single array. The program is then to convert these words in the array to actual phone numbers. Here is what I have so far.
import java.util.*;
public class Program1 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String begin;
int phoneNumber = number.convertNum();
[Code] ....
I realize that the second method doesn't have anything to return yet, I just wanted to put that in there while I was doing things that I actually know how to do ha. The convertNum() method is supposed to be the method with which the array of characters is converted to phone numbers.
I'm still trying to think my way through this. I would think it'd be easier to store the inputs from the user as individual letters rather than words for the sake of converting to phone numbers.
Also, we are only supposed to recognize the first 7 letters of each word that is entered, like the CALL HOME example, there are 8 letters but it's still a seven digit phone number, so I'm not sure how that would work.
Also, when printing the phone numbers after they've been converted, we're supposed to print the hyphen after the third number, I have no clue how that would be done from an array.

The code below is just the GUI for a slot machine. Currently when play is clicked it displays the random number, I'm trying to make it so each random number displays an image in the GUI instead. For example if the random numbers were 2,2,3 it would display Cherry, Cherry, Bells. I started changing field1 to the image but realised I was on the wrong track as it would just display the same image not one allocated to a number. I've left in what I started doing.
how to do it?

I need to write an input validation while using the do-while statement. I feel like most of it is good except that it gets stuck inside the brackets of the do statement. After I enter an input, it just keeps asking me over and over for an input. Then I have to make it s if you enter an input that is out of range, you have to keep entering an input until it is in range.

I have a number of cells which are Dates and need to have them appear in the same format. The samples I have seen usually create a new cell renderer object for each cell, even if its the same type. Since I have a number of Date cells I thought it best to use a single object for each of the date cells, but after seeing the different samples I am wondering if there is something I may be missing where using the same cell renderer object could potentially be an issue.
