How To Output Information Entered In JOptionPane Dialogue Boxes
Feb 25, 2014
I understand the basics of using the JOptionPane Message boxes, but how do i take the information that is entered and store it as a file, or print it. I'm in my 6th week of class, and this happens to be maintenance related.
import javax.swing.JOptionPane;
public class Example_Maintenance_System{
public static void main (String [] args) {
//Operator Name Input
String operator_name;
operator_name = JOptionPane.showInputDialog("Please scan your barcode");
I'm using the JOptionPane to display and receive information to/from the user. In addition to this, I am using StringBuilder to receive inputs from the user and then manipulate (append) that input to display the desired output.
//Example
(JOptionPane): "Enter text" (user input): Java is cool! (program): *stringBuilder.append(" I love it!") JOptionPane.showMessageDialog( ); .....
Psuedo-like code. The problem is that showMessageDialog(null, string) and not showMessageDialog(string, string). I want to display the enter text: " Java is cool! I love it! " in the JOptionPane. How do I accomplish this, since showMessageDialog only accepts (null, string).
This specific assignment requires me to write a program that calculates the total sales after each football game. There are 4 types of tickets: box, sideline, premium, and general admission. After each game, data is stored in a file... then output the number of tickets sold and total sale amount. Format your output with 2 decimal places.
Okay I know there is a I/O section and wasnt sure where to post this. I need some insight on how to use file input and output as well ... Here is my program:
import javax.swing.JOptionPane; import java.text.DecimalFormat; public class ticketsSold { public static void main(String[] args) { String BoxSeat; String SideLine;
What it is supposed to do is decide whether a ceiling fan is on or off, and describe it (color, area, speed). This is all user input (even pi) so it should decide whether to turn it on or off but for some reason skips over my if/else if statements all together.
I've tried changing it around a bit, looking up what my problem may be but this problem remains the same. my code:
import java.util.Scanner; public class CeilingFan { final int slow = 1; final int medium = 2; final int fast = 3; private int speed; boolean on = false; private double radius = 5; private double pi = 3.1415; String color = "blue";
I am trying to write a program that will generate a QR Code from an input text and also display some information about the input/output bits. So far I have created the frame and what to do next. And I'm not sure if I am on the right track since my level of programming is not that great. By the way, I am using zxing libraries from GitHub. I know, there are plenty of generators online for the QR Code, but that is not what I am looking for. As you can see on the attached image, I am more interested in the efficiency of encoding 2D data. Also, I noticed that almost all the online projects regarding 2D codes are for Android. Which is not very useful.
In vb.Net, when I do the code msgbox("hello world") and put it in a loop, it will execute that command and show a new messagebox for every time the code goes through the loop. I am wanting to do something similar with java but I'm afraid I don't know how.I know that the following code will display a messagebox as I am describing it
2) It will only display the first message box and when you press ok, the other message boxes will be disregarded and not displayed (I'm assuming because of the hang).
for my class we have to make a rock paper scissors game using GUI boxes. Everything is working fine I'm just having trouble displaying what the computer chose. In other words, after the user selects Rock, paper or scissors, the scoreboard just pops up displaying the score. Here's the last working program before I started tinkering with it.
// your code goes here import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.Icon;
I am trying to use JTextField. I have windows 7.I have jdk 8u45. I am trying to use multiple text boxes. I have written the following code:
import javax.swing.*; import java.awt.*; class Avg5Nums{ int num1, num2, num3, num4, num5; double Avg; Avg5Nums(int val1, int val2, int val3, int val4, int val5) {
I have to write an example program to fill boxes most efficiently with bags. All bags are the same size. The boxes come in Large, Medium and Small. Large boxes hold 20 bags. Medium boxes hold 10 bags. Small boxes hold 5 bags. I am getting input from JOptionPane input dialog box and then parsing that input to an integer.
I have to fill the large and medium boxes completely. I am not sure how to do this without an if statement. I can use one, but we have not covered it in class, so I am skeptical about using one to solve the problem. If I just divide the input number with integer division, I'm not going to get the remainder, right? So I'm thinking that I can mod my input number by 20 (the number of bags the user inputs) and then mod that number by 10 and then mod that number by 5, would that work?
From what I can determine check boxes are applied in SWT to the first column only of a table.
final Table table_project = new Table(g3_tabfolder_projects, SWT.BORDER | SWT.CHECK);
However I require check boxes on all cells. I tried creating a table for each column (which gives me my check boxes) but as the number of enries are often numerous and thus require vertical scroll the tables become out of sync (and to the user that sync is important).
Before I knock up some code to try and synchronise the tables I just wanted to check any alternative approaches. The project is SWT based.
I am creating a set of 3 subclasses, 1 superclass, and an application. In my instructions it says to make set methods in my super and subclass by using dialog boxes. In the application you have 3 different arrays where you create objects and are supposed to call the methods from the subclasses to be used in the application. I don't know how to make the dialog boxes from my subclasses to show up in my application.
I am working on a project in which I have three box (as of now) and each box will have some color of balls. So I am storing them in a Map of String and List of String as mention below.
Map<String, List<String>> boxBallMap = new LinkedHashMap<String, List<String>>();
Basis on the above input, I need to return a mapping which will be List<Map<String, String>>, let's say for above input, below mapping would be return as an output -
Here if you see, each row has alternate color of balls for each box - meaning blue for box1, red for box2, orange for box3 in first row. I cannot have same color of balls in each row. So this combination is not possible as it has same color of balls for two boxes in one row.
And also, in the second row, I won't use those balls which have been used in the first row for that box. In second row, box1 has red why? bcoz blue was already used in the first row for box1 and box3 has blue and no box2 in second row.
The output combination is getting generated basis on the input being passed as shown above.
Below algorithm might work but still not sure how should I fit this in the code -
- sort the boxes by the number of balls they have in it (ascending, from the smallest to the largest box). - while there are colors left - loop over the sorted list of boxes - in each iteration pick a color from the box (if there is one left), that is not already picked in the current iteration (of the while loop)
How to create text fields, labels and input boxes on a GUI, we haven't covered these in class as of yet, but I want my project to stand out so I'd like to know how to build a GUI now.
Is there anyway I can write a do while statement for this program. I haven't seen anyway to do it anywhere.
Java Code:
import javax.swing.JOptionPane; public class History { public static void main(String[] args) { //First Question: What is the capital of Mexico? String[] question1 = {"Mexico City", "Paris" //The choseable answers are made using String ,"Washington D.C", "Tokyo"};
import java.util.Scanner; import javax.swing.JOptionpane; public class Project { public static void main(String[] args) { Scanner input = new Scanner(System.in);
[code]...
This is the Error that i get in console!"Exception in thread "main" java.lang.Error: Unresolved compilation problem: JOptionPane cannot be resolved at Project.main(Project.java:10)"
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 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();
I am supposed to be doing a class assignment that calculates the area of a triangle and outputs with JOptionPane. I was able to fix some errors, but it's uncovering more errors.Here is my code:
public class Area { public static void main (String [] args) { double a, b, c; //Input sides of triangle double x; //Perimeter of triangle double area; //Area of triangle StringTokenizer st;
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).
import java.sql.Connection; import java.sql.DriverManager; import java.sql.PreparedStatement; import java.sql.ResultSet; import javax.swing.ImageIcon; import javax.swing.JOptionPane; public class Main

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?
I 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.
