Swing/AWT/SWT :: Slot Machine - GUI Exit Button
Mar 13, 2014
I've spent ages trying to implement an exit button into this code. Its the start of a GUI for a slot machine, the actual machine code is in a separate class and I haven't linked them yet. My question is where/how would the exit button be added? I've tried and failed a lot of times....
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class SlotMachineGUI
{
public static void main (String[] args)
{
//create new jframe
JFrame frame = new JFrame ("Slot Machine");
[Code] .....

//Variables for user input

I am designing a program that generates 3 random numbers from 1-5 and if 2 match, the user wins $1. If 3 match, the user wins respectively:
All 1s - $5
2s - $10
3s - $25
4s - $50
5s - $100
I first used a loop to run until the user runs out of money or wishes to stop. Then I made 2 methods. 1 to generate the random numbers and 1 to see if the user won any money. I am storing the random numbers in an array called slotnumber.
This is what I have so far but I am getting compiling errors at while (cont == 'y') {
import java.util.Scanner;
import java.util.Random;
public class SlotMachine
{

I'm trying to fix this logic error in my slot machine game where no matter what slot combo comes up, it says you have won $10 and proceeds to add that amount to the balance and subtract the bet amount to the balance, even though it is not a winning combo! I've been trying to solve that and when doing so, I commented out Slot1.randNum1 == 0, Slot2.randNum2 ==0, and Slot3.randNum3 ==0 and anything relating to see if that was the problem, and it seemed like it was, because after that, the logic error described above was gone, but in doing so, the loss/win counter didn't increment, nor did the program pick up on the winning combos. However, I do not know why commenting out anything relating to randNum ==0 would cause that.
Here is the code for the processing (as you can see, some parts are commented in attempt to fix the logic error, but right now the code below is for the logic error that keeps on telling that the user has won):
public void askData ()
{
title ();
int betAmount;
while (true)
{
try
{
c.setCursor (3, 1);

I want to create a slot machine in NetBeans, with JavaFX library (without using JavaFX Scene Builder) but i have some problems to create UI.
I created algorithm already but without visuals.
Now my code is:
public class BEST extends Application {
private ImageView var; //init imageview of images
public static void main(String[] args) {
launch(args);
[Code] ....
createbottom(); and creategr(); i wrote already (and my program creates grid pane of random images with double dimension array, random and imageview) and program runs, but i don t know how to keep track of credits balance,in the same time to create new random gridpane of images and to get rid of every gridpane.
Here is creategr();
private GridPane creategr(){
final GridPane creategr = new GridPane();
int[][] newarray=new int[3][3];
int w=100;
for(int i=0; i<3; i++){
for(int j=0; j<3;j++)
[Code] ....
Button "SPIN" is created in createbottom();.

For this program, I have to run a slot machine. It runs until right before the do while loop and then I receive the error: Exception in thread "main" java.util.InputMismatch.Exception. Searching around, someone said it was a scanner error and adding a call keyboard.nextLine(); fixes the problem- however with that I receive the same error.
Code :
import java.util.Scanner;
import java.util.Random;
import java.io.*;
public class SlotMachineSimulation
{
public static void main(String[] args) throws IOException
{
int number;

I have a Single Frame Application and I simply want to prompt the user with a dialog confirming they really want to close before they actually close the program, specifically when they click the X in the upper right. I THOUGHT it was like any other java application, with the slight added complexity of having to target the program-created-JFrame with: ".getApplication().getMainFrame()".
MyApp.getApplication().getMainFrame().setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
With that code, DO_NOTHING_ON_CLOSE is set on the JFrame, yet the program closes anyways. Which I don't understand.So I did some reading and found this: URL....That lead me to the configureWindow override, where I successfully tried this:
root.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
// write your code here
System.out.println("Window Closing");
}
});
But as far as I can tell that will only let me react to the window closing, not to the command to close it, where I could then kill the command in the dialog if they so "no I'm not ready to quit yet", if that makes sense. So, how to give a prompt before closing?I am using netbeans IDE to create this app - not sure if that is relevant, since maybe it is an oddity with the IDE and not Single Frame Applications.

I have a requirement where I have to send a file from a local system to unix box(present on client side) using java code.I have developed a code that is successfully sending the file from local system to client side unix box (I am connecting to client side unix box using VPN) provided I run the code in my eclipse IDE present in local system. But when I am running the same code in the unix box it is throwing null pointer exception.Might be the unix system is not recognising the local system. Please find the code.
package abc;

I 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 {
////////////////////
//TEXT PANE WINDOW//
////////////////////
//Set up a JTextPane object : The JTextPane is a specialized form of the JEditorPane
//designed especially for the editing (and display) of styled text.
final JTextPane pane = new JTextPane();

what I needed to know to complete the lesson, but now it just tells me what the output should be and I have to research the information on my own. anyways, here is my code from the previous lesson:
import java.util.Random;
import java.util.Scanner;
public class tnArray {
public static void main(String[] args) {
int [] array;
[code]....
Now I have to change it so that instead of counting the number of times a number will appear in the array, I must output which slot in the array the number is in.

I have a program I wrote long ago. I change colors of buttons at times. Here is the code:
for(int Player=0; Player < 8; Player++){
//make them all background
dealerLabels[Player].setBackground(new java.awt.Color(212,208,200));
}
//Now make the new dealer green
dealerLabels[dl].setBackground(new java.awt.Color(51, 255, 0));
The color of the buttons has always changed under XP but when I run the program on Windows 8 only the edges of the buttons change.

Can I add actionListener to a button component without creating a reference to it? Look at my code below:
public void init() {
setBackground(Color.red);
//Create the layout
setLayout(new BorderLayout(20, 5));
//Add buttons
add("North", new Button("Red"));
add("South", new Button("Yellow"));
add("East", new Button("Cyan"));
add("West", new Button("Magenta"));
add("Center", new Button("White"));
}
Or should I just do the usual instance.addActionListener(this) like myButton.addActionListener(this)?

I have been reading some java guides here [URL] .... and was trying to put a bit of what I have learnt into practice but am having some difficulty. Basically, using netbeans IDE I have created a new jFrameform so that I can place swing components in design mode. What I want to create isnt overly complicated but I just cant seem to get it. In design I have simply added a panel and a button. When I press the button I want to display an image I have located at:
/resources/images/numbers/1.png.
This is my code so far (most of it has been automatically generated from me adding things via design mode:
/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
package test;
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import java.io.*;
import javax.imageio.*;
[Code] ....
I assume I need something like below somewhere , do i need to create a draw method? if so how do I call it as it is expecting graphics2d as a parameter, what would I pass into it?
BufferedImage img = null;
try {
img = ImageIO.read(new File("/resources/images/numbers/1.png"));
} catch (IOException e) {
}
