Enter Password - If Correct Next Dialog Box Will Pop Up
Feb 28, 2015
The goal of this section of my assignment is to ask the user for a password. The password entered has to match the password I set in the code. If it is correct the next dialog box will pop up.
my password is set to:
String enterpwd = "";
String correctPassword = "Setpassword";
I am asked to use JOption, I completed as follows:
enterpwd = JOptionPane.showInputDialog(""............JOptionPane.QUESTION_MESSAGE);
then I use IF statements
if (enterpwd == correctPassword)
xyz = JOption .......();
I am getting an error "java.lang.NumberFormatException: For input string: """

My homework is asking me to write a program that prompts the user to enter a password and displays "valid password" if the rule is followed or "invalid password"
Sample
enter a string for password: wewewx
valid password
It's being graded on
Design of my GUI
Dialog box
User friendliness
Creativity
My current issues with the current code I have written is simply the password doesn't work unless it starts with 2 digits, the other order it displays as wrong. and I have no idea how to add a GUI.
import java.util.*;
import java.lang.String;
import java.lang.Character;

I found different ways to code this for a button named "closeButton":
- closeButton.getRootPane().setDefaultButton(closeButton);
- thisDialog.getRootPane().setDefaultButton(closeButton);
- SwingUtilities.getRootPane(closeButton).setDefaultButton(closeButton);
Which is best?

I simply need to write a program that asks a user to input a password. It has to be in this format: DDD-LL-DDDD. The D's mean Digit and the L's stands for Letter. The User has to enter the Hyphens.
If the password isn't entered in that exact format the program should read out a error. If the hyphens aren't entered the program should read out a error. If there are too many characters entered, there should be a error.
import java.util.Scanner;
public class security {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Enter Security Code: ");
System.out.println("Use the format: DDD-LL-DDDD and include dashes");
String code = input.next();
char c;
[Code] ....
I'm trying to figure how how to get the code to check if the values entered are in the correct place. I'm also not sure how to make the program check for hyphens. I feel like I'm close though. I can easily add the correct error and valid messages later if I could just figure out this part.

I wrote a java program for my gui number converter app, the main purpose of this program is to make sure that user enters only a binary number for conversion from binary to other number formats. the problem is my program keeps prompting me to enter correct binary number, no matter if i enter correct binary number, it will still keep prompting me to enter correct number. Here is the code
import java.util.*;
public class test {
Scanner key = new Scanner(System.in);
String in;
int b;

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!

How to improve my code. I finally was able to create a program that gives you the corresponding letter grade, when you enter in a numeric grade without using an array. The only issue left is that I have to be able to enter 5 grades at a time, and it give me the letter grade for all 5. I have the programming working, but only am able to enter 1 at a time. I am not sure what kind of loop or if I am supposed to use a loop.
public static void main(String[] args){
{
int grade = 0;
Scanner input = new Scanner(System.in);
System.out.println("Enter : ");
grade = input.nextInt();
if (grade >= 90)

This is the code I have written so far. This program calculates tax from multiple tax payers.
import javax.swing.JOptionPane;
public class CalcutateTax
{
public static void main (String [] args)
[code]....
The problem is I cant think how to ask the use if he wants to calculate tax due for another taxpayer. If the user says yes, keep calculating, otherwise exit from the program. And how do I keep count of how many people got their tax calculated? Say for example,
JOptionPane.showMessageDialog (null, " We calculated tax for " + xnumber + " number of people.");
This is the question asked on my assignment ask the user if he wants to calculate the tax due for another taxpayer if so, do it again.At the end of the main method, output a message in a dialog box that says: Hello, We calculated taxes for [number of taxpayers].replace [number of taxpayers] with the actual number of taxpyers you calculated taxes for.

I am in my first Java class and this is the second assignment. I am supposed to write a program that prints a table of squares and cubes and also uses dialog boxes for the input and the output. The output should look like this:
0 0 0
1 1 1
2 4 8
3 3 27
. . .
. . .
. . .
10 100 1000
I've figured it out but my only problem is the output dialog box displays each row individually (a new dialog box pops up for each row). How do I get it to display the whole table???Here's my code:
Java Code: import java.util.Formatter;
import javax.swing.JOptionPane;
public class Homework2 {
public static void main(String[] args) {

I have managed to write the program where the user can input kg and the formula converts it into lbs. I have also written a program where I can get a dialog box to appear to ask the user to input the kg, but I can't figure out how to combine the two.
This program allows the user to input the kg, it converts it to lbs and then displays the output:
import java.util.Scanner;
import javax.swing.JOptionPane;
//creates a dialog box
public class convert {
public static void main(String args[]) {
[Code] ....
This program only brings in the first variable and the initial dialog box:
import java.util.Scanner;
import javax.swing.JOptionPane;
//creates a dialog box
public class KgLbs {
public static void main(String args[]) {
[Code] ...
I have attached the actual assignment and what the program should look like.

The below program ask the user to enter the value of x 1 , Y 1 and radius in separate boxes , What would look nice is if the user can Enter the Value X ,Y and radius in the same box.
import javax.swing.JOptionPane;
public class C3E29GeometryTwoCircles {
public static void main(String[] args) {
// Ask the user to enter the x1 coordinate.
String strNumber = JOptionPane.showInputDialog("Enter the value of x1 coordinate " );
double x1 = Double.parseDouble(strNumber);
strNumber = JOptionPane.showInputDialog("Enter the value of y1 coordinate " );
double y1 = Double.parseDouble(strNumber);

I have to return the minimum and maximum value entered by the user, so far the program returns the maximum but the minimum stays at 0. I assigned 0 to the min and max variables. I believe that is part of the problem, but why do I get an accurate answer on the max if both variables are assigned to 0?
int min = 0;
int max = 0;
int option = JOptionPane.YES_OPTION;
while ( option == JOptionPane.YES_OPTION){
String dataString = JOptionPane.showInputDialog("Enter an integer");
int data = Integer.parseInt(dataString);
if ( min > Integer.parseInt(dataString)) min = Integer.parseInt(dataString);
if ( max < Integer.parseInt(dataString)) max = Integer.parseInt(dataString);
option =JOptionPane.showConfirmDialog(null, "Continue?");
}
JOptionPane.showMessageDialog(null, "Minimum: " + min + "
Maximum: " + max);
}

i need to develop a java program in which it will ask the user "Username" and "Password" and by which it will login to a wesite.
I have developed a GUI in which the username should be entered in the User "JTextfield" and Password in Password "JPasswordField". I need to make sure that password should not be displayed in the GUI. but I didnt find a way to parse the string (char) entered in the "JPasswordField" to the website.
It is always passing a 'null' character! I tried to search in internet and i found that it wont be able to pass the passwordfield characters but you will be able to check in the main function itself by comparing with another char array in the main program itself whether the password entered is correct or not.
Is there any alternate way for this?
Objective : Parse the password (which is not displayed in the GUI) to a website or some other function where it will use it

I have a question but dont know how I could verify the criterias..
The password should be at least six characters long
The password should contain at least one uppercase and at least one lowercase letter
The password should have at least on digit
Write a class that verifies that a password meets the stated criteria. Demonstrate the class in a program that allows the user to enter a password and then displays a message indicating whether it is valid or not.
I have not created a class because I really have no clue what to write in this case. My main method is:
import java.util.Scanner; // Needed for the Scanner class
public class Password {
public static void main(String[] args) {
// Create a Scanner object to read input.
Scanner keyboard = new Scanner(System.in);
String input;// To hold the input
