GUI Program Overlay - JButton As Action Item To Display Information To JTextFeilds
Mar 6, 2014
I have some questions about a GUI program overlay. My main method in the "actual code" will display information in a huge batch, which is necessary. My questions relate to this feat. I am curious because I need to look this up but I am unsure of the "name" for what I am trying to accomplish.
Can link a JButton as an action item to display information to the JTextFeilds that houses the information needed to populate the data?
If so, what are the necessary steps to ensure that my JButton class and listener are pulling the correct information upon the Event and populate the data to the JTextFeilds?
Would I need a boolean statement that captures all of the methods of "data procurement" within my JTextFeilds underneath that one button?

I have been creating a Java program to track inventory using an array. I need to add a search function to it to take a term, input through a text field, and locate a matching instance within the array. How can I code a JButton to grab test input from a JTextField and search for it within the array then display the corresponding information? I also need to add buttons to add and delete items as well.

I am trying to create a GUI with already existing code. My assignment is: Modify the Inventory Program to use a GUI. The GUI should display the information one product at a time, including the item number, the name of the product, the number of units in stock, the price of each unit, and the value of the inventory of that product. In addition, the GUI should display the value of the entire inventory, the additional attribute, and the restocking fee.
Where to start. The text book does not cover a GUI that displays this type of information rather it just displays graphics. I would like to create a separate class that holds the GUI information just to make everything flow better. I have provided my current code below:
Java Code:
// ProductTest.java
// by JakeB
public class ProductTest {
// main method begins
public static void main(String[] args) // begin main {
myGUI display = new myGUI();
display.setVisible(true);
[Code] .....
This is all I have for the GUI. I am at a total loss and I am behind 2 weeks now. I cannot move forward until I am able to get this done and the class ends next week.

I cannot...(actually do not know) how to change the actionlistener (actionPerformed) after the second click in an array of JButtons. This is how the program performs right now.
On the 1st click on the grid, the border of the button clicked will change to 'blue' and another button will change its boarder to 'red'. on the next click the same action is performed.
What I need is to change action when the 'red' bordered button is clicked, lets say change the color of the buttons from the 'red' to the 'blue' buttons.(x 3 buttons).
The logic about how to perform the final result I think I can do on my own but my problem is how to change the action when the red bordered button is clicked.
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.GridLayout;
[Code].....

I have a simple display method in a java project as given below:
public void displayInfo() {
for(Student student : studentdB){
System.out.println(student.toString() + "
");
}
I would want to use one of Swing components to display the students instead of displaying them on the stdout. How I could go about calling this method in some Swing components that can display all the students in the studentdb?

I'm new to java and I'm currently trying to make a program that uses a JTree that implements a properties file. I have the Keys set to the nodes but I want it so that when the node is clicked it will retrieve the keys value from the prop file.
I did have some code for this initially but I as it did not work at the time and was causing issues to my project I got rid of it. I have my code for the jtree,the listener and the prop file.
Tree
Java Code:
JPanel panel_1 = new JPanel();
panel_1.setBackground(Color.WHITE);
panel_1.setSize(new Dimension(22, 0));
scrollPane.setViewportView(panel_1);
Properties properties = new Properties();
[Code] ....
Java Code: add = Adds files changes in your working directory to your index. Example: git add .
rm = Removes files from your index and your working directory so they will not be tracked.
Example: git rm filename mh_sh_highlight_all('java');
Is there a way of doing this? Been trying for a while now but to no prevail. The image is what it currently looks like

Right now we are learning about arrays and using the try/catch. Code below, I am trying to just display information about buildings. The application is good but not with the try and catch statement. I'm trying to just display the message of "please enter a building number" when a user puts a letter instead of a number(InputMismatchException) and then the user would have to put in one of the numbers. But when it runs and i put in a letter, it reads the message, but it always outputs the first building information ...
package username;
import java.util.InputMismatchException;
import java.util.Scanner;
//TallBuildings
public class TallBuildings {
//compare heights of buildings

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).

I'd like to draw an overlay on an image. The overlay is also an image with a black background and a white foreground. Now the white pixels should be drawn on the image in red. This is possible with the code I posted below. However, the problem arises when rotating the stencil (overlay). I get some interpolation errors from the rotation on the boundaries. I tried to clip them with setClip(), but this turns the background from transparent to white. How to remove those spots? Or maybe a completely other idea of achieving an overlay on the image? I'm aware of the pixelreader and iterating through the stencils pixels and draw the respective pixels as rectangles on a Canvas' graphicContext. However, this was extremely slow, compared to the code I posted below (although it doesn't work with rotations).
Here I surrounded the errors:
The image:
The stencil:

import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.*;
import javafx.scene.effect.BlendMode;

import javafx.scene.layout.HBox;
import javafx.scene.paint.Color;

ABC is a company that designs and prints personal business cards. The company has asked you to write a Java application to display the layout of the information in a typical business card order. Data items in a typical business card include the customer's name, address, city, state, postcode, home phone number, and work phone number.
Write, compile, and test a Java class that displays these data items in a command window. Alternatively, you could also create it using a dialog box. Please include appropriate comments in your class.
Please named your class BusinessCard(LIM).java. (eq. BusinessCardLIM.java)

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.
// QR Code Generator
package qrcode;
import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.border.EtchedBorder;

public void actionPerformed(ActionEvent e)

for (int i = 0; i < bkSorted.length; i++)
{
textArea.append("

When I click the button, it displays the whole array, instead of just the next array position. What am I doing wrong?

Write a program using switch statement to allow users to choose an item of a menu. For example, the menu looks like the following.
File menu
1. Open
2. Close
3. Save
4. Exit
Enter your choice:
If you type 1, then your program should print out "Open is selected" (double quotes not included).
Notice:
(1) Using Scanner to get user choice;
(2) If the number user input is not in {1,2,3,4}, your program should let user know that.
Here's what I have:
public static void main (String[] args) {
int user = 1
switch (1) {
case value: 1
System.out.println ("Open is selected");

I'm working a an assignment for my IT/215 class and I'm having a little trouble with my arrays. My code compiles just fine but when it comes to displaying the information I've input into my array it doesn't seem to want to and I'm not sure what I'm doing wrong here. On line 136 originally I had [DVDs [count] = count+1]] but it wouldn't compile. I then put line 136 to [ DVDs[count] = new Inventory();] and I think that's were my issue is but I'm not sure....
// Purpose:the purpose of this software is to display inputs as wells as the stocks and price of inputs.
class Inventory

private String ItemName; //to store Item name
private double UnitsInStock; //to store number of units in stock
private double UnitPrice; //to store Unit price

I'm making a program that displays information for "employee" objects of different types. This works with a hierarchy that goes Person→ Employee→ Fulltime/Adjunct, and a driver that tests the inheritance. The Person class is given and only supplies the name, the employee class manages the year hired and the ID, and the types of employee classes manage the salaries.
One object (called staff[2]) is supposed to first be printed with default information and then later updated via set methods. I figured out how to update the name, but I don't know how to update the rest of the information because the employee's name is managed in the Person class and the reset of the information is managed in the less-general classes, and the objects are all in an array of Person.
How do I call the set methods necessary to update more of staff[2]?Output (scroll to see the updating section)
The current year is 2012
Name: Flintstone, Fred
ID Num: BR-1
Year Hired: 2005
Years Of Service: 7
Salary: 65000.12
Fulltime Type Employee

I work for my local probate court, and one service we offer is email reminders. They fill out a form, it's entered in the system, and they will be notified when something is due. I've been allowed to create a program that will allow me to enter the information from the form to keep track of the attorney's who have signed up.
import java.sql.*;
import java.util.*;
import javax.swing.*;
import javax.swing.table.DefaultTableModel;
public class Attempt1 {
public static void setConnection() throws SQLException {
Connection conn = null;
Statement state = null;
[Code] ....
The issue I have is the method setQuery. It displays a table with the data entered. Where it currently sits at line 21, it does not display the table, nor does it seem to terminate the program. The goal was to update the table with a few entries, and then display the Jtable. When placed above the setInsert method, it displays just fine, and will reflect the new entries added the next time you start it. I'm still learning Java outside of a classroom environment on my own, so I can only imagine that this is riddled with poor coding, but I just can't seem to figure out why it doesn't display the table after the setInsert method is called. In it's current state, this program is just meant to test functions of SQLite with Java. From there it will be created with a GUI.

The main method will drive your program by doing the following:
-Create an array to hold all the individual golfers and par scores (type is Golfer[ ]).
-Prompt the user for a data file containing the Par scores and the player names and score. The format of the input file should look like
Par, 3, 4, 4, 3, 4, 3, 5, 3, 4
George, 3, 3, 4, 3, 4, 2, 3, 3, 4
Paul, 4, 5, 4, 3, 6, 3, 4, 3, 5
Ringo, 3, 3, 4, 3, 4, 2, 4, 3, 4
John, 4, 4, 4, 3, 4, 2, 5, 3, 4
Your program should read the file contents and store the information in your array of Golfers.
