Here's My code to create multiple JTextfields in a Single Option Pane.
My goal is simple.
Take some input from the user and then store it a TEXT File.
package printer;
import java.awt.Toolkit;
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
import javax.swing.*;
public class Database {
JTextField name = new JTextField();
JTextField roll = new JTextField();

I need to create a JFrame with a user given amount of text fields in the form of a matrix. Say the user inputs 5 rows and 5 columns, I need to read those ints and create a 5 by 5 box of JTextFields in matrix form (i.e. 25 total text boxes in the form of a box). Here is some of the code I have been trying to use to do this...
int x = 10;
int y = 10;
for(int i = 0; i<rowSize; i++){
y= y+40;
for(int k =0; k<colSize; k++) {
newField = new JTextField("0");
newField.setBounds(x,y,40,20);
win2.add(newField,0);
win2.repaint();
x= x+60;
}
}
In order to go through the loop a given amount of times and create that amount of text fields in the correct places.Am I even close to doing this right?? Cuz I can't get the text fields to even show up on my window.
Code given below does real time validation for 2 JTextFields. While entering some values to txt1 and txt2 enables the save button and removing values from txt2 or txt1 reset the save button to disable. I use Netbeans as IDE.What I want to do is, enable Save button after checking multiple JTextFields for validity. If any of the text fields is empty, btnSave must be disabled.This program gives expected result up to some extent. But there is little issue. After form appears for the first time, When I type something on Textfield1, Save button enables without checking Textfield2. This happens only at the first time.
public class NewJFrame extends javax.swing.JFrame {
private Boolean isValidFromTextField1 = true;
private Boolean isValidFromTextField2 = true;
public NewJFrame() {
initComponents();
btnSave.setEnabled(false);

I am making a Sudoku game and creating a matrix of JTextFields. However I am getting the following errors
Exception in thread "main" java.lang.NullPointerException
at SudokuView.board(SudokuView.java:30)
at SudokuView.<init>(SudokuView.java:18)
at SudokuMain.main(SudokuMain.java:5)
I know the problem is with this code
box[i][j] = new JTextField();
panel.add(box[i][j]);
I know this because when I do this:
panel.add(new JTextField());
It works. However it puzzles me why it is not working.
Whole Code:
import java.awt.GridLayout;
import javax.swing.*;
public class SudokuView {
JFrame frame;
JPanel panelBoard;
JTextField[][] box;
int row=10; int col=10;
SudokuView(){
frame = new JFrame("Play Sudoku GOOD LUCK");

I was assigned to create a program that opens up a window that asked the user for an input of 0-10. This input will create three windows with the correct number of rows and columns of JTextFields in the form of a matrix. the third window has a button that adds the two matrices (which also take user input) and adds them together and prints them in the correct matrix fields. I am having trouble declaring the 2d array from the user input and creating the windows with the correct amount of jtextfields to move on with my program.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;

private JFrame win1, win2, win3, win4;
private JButton button1, button2;

I am trying to create an event handler for two JTextFields to only allow numerical input. It consumes all letter but for some reason the "n" key still gets through. I have the spaghetti code below.
public void keyTyped(KeyEvent in) {
char input = in.getKeyChar();
if (in.getSource() == scaleField){
if (!(Character.isDigit(input) ||
(input==KeyEvent.VK_BACK_SPACE) ||

I am working on my second javafx program and I am getting confused. The program that I am writing is a payroll calculator. A secondary window opens at the start of the program where the user first enters the number of employees and clicks submit to save the number and to close this window. Then, the user begins to enters the employee information (first name, last name, pay rate and hours worked) when the user clicks the NextEmp button, I want the data in the text fields to be entered into arrays for later use, then clear the fields for the next use. I am running into 2 issues. The first is the close event for the secondary window that pops up. I cannot figure out the syntax. The second issue that I am running into is the loop to store the data into the arrays. I believe I am getting the text field data correctly, but I cannot figure out how to stop the loop until the NextEmp button is pressed again.

I have an ArrayList of JTextFields in a CAMSetup1 class that contains a bunch of named JTextFields: Layer_textField_1, Layer_textField_2, Layer_textField_3, ... etc
I would like to check the .isEnabled status of a particular JTextField in that ArrayList from my main class by passing the name of the JTextField to a method in the CAMSetup1 class as a string
The peice of code calling the method from the main class is something like this:
if (CAMSetup1.getFieldEnabledStatus("Layer_textField_1") == true) {
data.writeToFile(CAMSetup1.getFieldText("Layer_textField_2") + " LAYER 2 LIST FILE
");
}
The method for checking the .isEnabled that I have so far is:
public boolean getFieldEnabledStatus(String textFieldname) {
boolean status = false;
//<need code here>
return status;
}
I also need getting the text:
public String getFieldText(String textFieldname) {
String filename = false;
//<need code here>
return filename;
}
I have made a window using JFrame and on my JPanel I have added 3 components: 2 JTextFields ("field1" and "field2") and inbetween them a JButton ("switch"). My goal is to switch the value of field1 to field2 and vice versa when the JButton is clicked. I thought this ActionListener which I have added to my JButton would achieve my goal:
public void actionPerformed(ActionEvent e) {
field2.setText(field1.getText());
field1.setText(field2.getText());
}
However, it changes the value of field2 into the value of field1 but not the other way around.
Is there anyway I can write a do while statement for this program. I haven't seen anyway to do it anywhere.
Java Code:

I am writing a program that has to do with ciphers and cipher shifts. The program itself works fine, but I am having trouble printing out the answers to JOptionPane. I know the basics of JOptionPane, but my problem is this:
Majority of my program takes place in a for loop, and resolves the cipher (it is a basic cipher program) 1 digit at a time. So, only the last DIGIT (I don't know how to convert a digit to a CHAR in JOptionPane) is printed to JOptionPane. Here is my code:
public static void main(String[] args) {
String cipher = JOptionPane.showInputDialog(null,
"Please enter a sentence or word that you wish to encode or decode. This program uses " + " a basic cipher shift.");
int answer = 0;
String upperCase = cipher.toUpperCase();
char[] cipherArray = cipher.toCharArray();

Just wondering if there was a way to change a JOptionPane's display message dependent on the button the user is hovering over. I.e.: Hover option1, shows one message; hover option2, shows a different message, etc.. but within the same JOptionPane (not showing a new one).

I cant custom my own icon. There is no error. But the image that I tried to show in the joptionpane is not showing. What should i do?
I am a beginner in Java and I am currently learning about JOption pane.Using Strings I am accepting an input from the user and by using the Interer.ParseInt(variable) option I am able to multiply this two strings using the code below.
String Length;
Length = JOptionPane.showInputDialog("Enter the Length");
String Breadth;
Breadth = JOptionPane.showInputDialog("Enter the Breadth");
System.out.println(" Area is " + (Integer.parseInt(Breadth) * Integer.parseInt(Length)));
System.exit(0);
How Do I make my code accept Decimal values. E.g. My Code should accept 10.02 as Length and 20.42 as Breadth and give the product a Decimal.
Is it possible to make it so that when the popup box comes up I will only be able to click on the box? For example, I would be browsing the internet while the program is running and then the box pops up and I am forced to answer the question before I can click on anything else. If it is possible, how do I do it?
View Replies View RelatedI am quite familiar with using JOptionPane and its various displayXDialog() methods and reasonably familiar with changing fonts.
I have a JOptionPane.displayMessageDialog() that is working fine but I decided to make the font larger.
I found an example from which I coded:
Font font = UIManager.getFont("OptionPane.font");
UIManager.put("OptionPane.font", new Font(font.getName(), font.getStyle(), 24));
font = UIManager.getFont("OptionPane.font");
JOptionPane.showMessageDialog(this, "Welcome to Mover", "About Mover", -1); // no icon
After the UIManager.getFont() call after the UIManager.put() call, font shows the new font size of 24, but the showMessageDialog() dialog still has the default font.
And yes I understand that, when this works, it will affect every JOptionPane in my program.
I also tried:
Font font = UIManager.getFont("OptionPane.font");
JOptionPane message = new JOptionPane("Welcome to Mover", JOptionPane.INFORMATION_MESSAGE);
JDialog dlg = message.createDialog("About Mover");
[Code] ....
This gave me a dialog with the default font and an unwanted icon.
So I tried
// both
Font font = UIManager.getFont("Dialog.font");
// and
Font font = UIManager.getFont("JDialog.font");
and planned to use that font in my setFont() call but font was null.
I have to make an application called miles to meters that converts miles to meters that asks for user input through joption pane and the output can be eather system.out.println or joption pane, I found the code i need but it uses buffered reader for input not joption pane. Here is the source code

import java.util.*;
class MetersToMiles{
public static void main (String[] args)throws
Exception{
// 1 meters = 0.00062137119 miles;

public static void main(String[] args) {
//Needs to add a scanner to the program to continue on
Scanner keyboard = new Scanner(System.in);

Now I need to create a second version of this program that uses JOptionPane to get the inputs from the user and show the output!
When I use this code
import javax.swing.*;
public class Swag {
public static void main ( String[] args) {
String name = JOptionPane.showInputDialog("What is your name?");
String input = JOptionPane.showInputDialog("How old are you?");
int age = Integer.parseInt(input);
System.out.print(" Hello, " +name);
System.out.println("Next year you'll be " +(age+1));
}
}
And run it, it ends up looking like thisH1765.png I'm running windows 8, the latest x64 JDK, no type of custom font or anything that I know of. I've run this through eclipse, CMD, and uninstalled and reinstalled Java. I tried using another example of JOptionPane usage from a site and running it, still looks the same.
For some reason the two JOptionPane message boxes at the end of my code don't seem to open when I run the program.

Here's what I have so far.
