I am required to read user input to create two matrices which will eventually be added together. I am unsure as to how I can read the input from the user as an int and not a String. The input is from size 0-10 for both column and row size. Also, can you have a new button created in the actionPerformed method of a previous button?
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

private JFrame win1, win2, win3, win4;

View Replies View RelatedI am new to Java, I am using Netbeans to create a simple GUI with one button that just says "play". I want this to play an mp3 file i specify. I have found code to simply play a WAV which works great.There is lots of information on the net about playing an mp3 but it's all long an complicated. There must be a simple way to just have java play an mp3 file.
View Replies View RelatedI want to create a button bar that is the same as the confirmation dialog button bar -- so an OK and cancel button layed out in the platform specific way, and with the same styling.
I have made some progress via a hack -- create an alert dialog, and extract the buttons in the dialog using lookupButton, and then put those buttons in a toolbar. But this doesn't necessarily get a toolbar with the buttons in the correct order. If I could get the button bar out of an alert dialog I would have a solution, but I can't see to do that.
The gist of it is to create a very basic memory game. There are 12 buttons, each associated with an icon. Every button that you click will display the icon and will stay there until clicked again. I got the bulk of it taken care of, but my issue lies with switching the icons back and forth. I can get them to display one at a time, but when I click on a new button, all the icons except the button I just clicked don't display. Essentially, only one shows up at a time.

View Replies View RelatedI am creating a mad libs type program. This section of code is for the user to be able to make their own mad lib template (that people will be able to fill out later). The normal blanks in a mad lib are for verb, noun, adjective, adverb, etc. I cam up with 13 or so of these buttons, but it would be nice that if the user wants to add a button that they think we missed, such as 'Person in the Room' or 'Silly Location'...that the user would be able to do this. I sort of pictured there being a button that says 'add button' or something like that. Is there a ways to do this with the way I've set things up?
public class MadLibs {
public static void main(String[] args) throws IOException {

I have a supermarket checkout line where i have a list of available products on the left and then a basket on the right with the products in. The products are listed in an array, here is the product class
public class Product {
private String name;
private double weight;
private double price;
[Code] ....
with getters and setters excluded, and the list these are put into
public class productList extends DefaultListModel {
public productList (){
super();
}
public void addProduct (String name, double weight, double price, int code){
super.addElement(new Product(name, weight, price, code));
i have the price for each product to be displayed in a text field with the following code
addBasketItem = new JButton();
getContentPane().add(addBasketItem);
addBasketItem.setText("Add >");
[Code] ....
defaultCheckoutList contains my available items and defaultMainList is the basket, with mainTillPrice being the jtextfield.
This works to get the price however it just replaces each time i make a new entry with the price for the next item, i want a total of the price of all the items i have added, but not sure how.
I enter a value in the text box in one class and want to pass that value to another class in order to compare it and color the cell in a table. In the first class I have
package cege.ui;
import cege.controller.HtmlController;

...
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
[Code] .....
How to pass the threshhold from the first to the second class?
Will I'm tying in my code to set a default number for the JTextField that when the user decide not to put any numbers. Like let say that I want the textfield set to 0 , so then the user do not file it it won't make any problem to the program because its already has a default number.
if (stringGQ != null && stringGW != null && stringGP != null){
stringGQ = gMQ.getText();
stringGW = gMW.getText();
stringGP = gMP.getText();
weightPrice_1M = Double.parseDouble(stringGW) * Double.parseDouble(stringGP);
[Code] .....
Note: This is a small part of my code. when I leave it empty it take the 0 as a value, However, when I write in text field it also take the value of a 0 and the finalTotal is also = to 0.what I'm doing wrong.
I am creating a slot machine using eclipse. I am trying to get the "winnings" JTextField to be updated in a way so that when the random images have been selected it adds to the number that is already displayed in the JTextField as opposed to what it is doing at the minute which is just displaying how much was won on that particular spin. I am also struggling to set a code for when noting is won, nothing is added. My code is below.

import java.awt.event.ActionEvent;

View Replies View RelatedI currently building a hotel reservation system, and I'm having issues with retrieving and setting other values from a JTextField.
What I'm trying to do is to retrieve the value that was inputted into a textfield, and then setting that value to a string in another class.
In here, I'm trying to retrieve values from the JTextField:
@Override
public void actionPerformed(ActionEvent event) {
GuestInfo gi = new GuestInfo();
if (event.getSource()==roomView)
{
roomViewFrame.setVisible(true);
roomViewFrame.setSize(1000, 600);

designing a program which allows you to buy stuff from the jframe with 10x items each with different pricing, so once you click the image button the cost of that is displayed in the textfield, ive been trying to set the jtextfield to a decimal point but have not been able to so far,
if (source == jBSofa) {
System.out.println("Sofa");
{
dTotal = dTotal + 599.99;
jTotal.setText(Double.toString(dTotal));
DecimalFormat myFormatter = new DecimalFormat("#####.#");
String output = myFormatter.format(dTotal);
a visual aspect of it.
How would I display certain output text if the text entered equaled "text".
So lets say you enter a question into a JTextField. You press a button that submits the text. The output displayed depends on what the question you asked was.
Think about it as "If question = What color is the sky? On submit, display text "Blue". How to implement this.
I have been reading several suggested solutions for implementing autocomplete for a JTextField. However, the documentation is a bit confusing to me. It seems like they mostly require switching to a JComboBox. Can I or can I not continue to use a JTextField and implement an autocomplete feature? I also saw what I thought was a built-in autocomplete "decorator" for swing objects (although it was not clear if it can be used for JTextField) but most of the implementations seem to start from scratch. Any simplest way to implement this (assuming those 2 conditions are not mutually exclusive)?

I am trying to get the data entered in a JTextField into a JTable but not clear on how. The LeftPanel is where the button is located and the RightPanel is where the JTable is. I want the actionPerformed to update the row of the JTable but I can't figure out how. There is another class that controls the GUI but did not think it was necessary to include. Also, I am aware that I am getting an error at the addRow line, can't seem to alleviate it.
public class LeftPanel extends JPanel {
private static final long serialVersionUID = -2311952438693382407L;

I have a GUI with a JTextField. I need to check that the input entered by the user is made up of only integers.
For example I accept: 1, 10, 530, ...
I do not accept: -10, 1.5, -6 ...
I would like to implement this control by using a regular expression so I would have a code like that.
JTextField text = new JTextField();
String input = text.getText();
boolean bool = checkInteger(input);
if(bool)
System.out.println("Ok");
else
System.out.println("Error");
The checkInteger(String input) method should check if the input string is correct or not.
How can I do to implement this control with regular expressions?
Is there an easier way to do it?

I'm working with a project there ill need to enter some values for an Object and for this i'm using JTextField. However some of the variables are of the types double, int and bool. Is there a different method of reading thees types?
for example:
double playTime = this.playTime.getText();
This won't work because playTime is of type double and .getText(); takes a String.
How will i handle this? Id rather not convert from String to Double if its possible.
