Actions For Multiple Dialogues

Jul 19, 2014

I have two dialogues: one name "dialog" and another named "queryDialog". Each dialog has one button among other things and they are supposed to make their respective dialogues hide when clicked. But the second button doesn't work.Here is my code:

Java Code:

import java.io.*;
import java.util.*;
import java.util.concurrent.TimeUnit;
import com.sun.management.OperatingSystemMXBean;
import java.lang.management.ManagementFactory;
import java.lang.System;

[code]...

I tried to follow the example of How to add multiple ActionListeners for multiple buttons in Java Swing - Stack Overflow but there seems to be a problem.

How To Add Actions To The Buttons

Dec 22, 2014

I have started to create a calculator using Java SWING. I am new to this and don't know a huge amount. I don't know what to do now.

How do I add actions to the buttons? So when the button is pressed it will appear in the text area?

Where do I put these commands also? Within public void gui?

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
lic class Calc extends JFrame implements ActionListener {
  private JButton ZeroButton = new JButton("0");
private JButton OneButton = new JButton("1");

How To Take Different Actions For Different Ranges Of Data

Mar 18, 2014

My professor like us to make a salary, taxes and etc exercise. which we should type the name first then, input salary. then if we input the amount 8000 or higher. the system will ask another question about the marital status. and that is it.

My real problem is when we input 5000-7999 the system should ask a different question, stating do you want to pay for your premiums and a follow up of yes and no choices. if we input 0-4999 the system will just state that it is your current salary.... etc..

package exer5;
import java.util.Scanner;
public class Exer5 {
public static void main(String[] args) {
Scanner Kirk = new Scanner (System.in);

Rendering Actions In A Combo Box?

Feb 2, 2014

When I add an array of action-objects (the class extends AbstractAction)

to a combo box, I do receive the action performed events, great!

But the combo box items show the long string of the action object, of course!

How to render that string in a way that only the Action.NAME appears?

I was experimenting a little, but could not make it to work:

Java Code: private class ComboRenderer2 extends BasicComboBoxRenderer {

How To Use Actions In Java Program

Apr 18, 2010

I have spent quite a few hours trying to follow an API on how to use Actions in a java program.

I have 3 JButtons and have just added a JMenu. What I want to do is to add an ACTION so that the JMenu performs the same function as the JButtons. (i.e. they both do the same thing).

I have tried to copy and follow the example from the API forum.

How to Use Actions (The Java > Tutorials > Creating a GUI With JFC/Swing > Using Other Swing Features)

The first error I get in compiling is on the following line:

Action loadFile = new LOADFILE();

However, I get the following error message:

softeng2final2.java:49: cannot find symbol
symbol : class LOADFILE
location: class softeng2final2
Action loadFile = new LOADFILE();

How To Get One JButton To Perform Sequential Actions

What Are Interleaving Operations - Can Atomic Actions Interleave

Mar 24, 2014

I have read that when two threads have two steps (of execution) and each step involves many operations, then the operations of both the threads kind of overlap one-another. For example

I think I am not very clear about interleaving actions/operations? Especially when we say that atomic actions can not be interleaved. But

Java Code:

class Counter{
private int c=0;
void increment () {
c++;
}
void readIn () {

[Code] ....

And the following sequence of events occurs.

Thread A: Retrieve cThread A: Increment cThread A: Store the result in cThread B: Ask the user to enter a valueThread B: Read in the value, store it in c

Now the value of c obtained after increment will be lost (Thread Interference). Isn't this an example of interleaving operations?

Start Client Actions Only Once All Clients Connected

Aug 30, 2014

I was tasked to do a 2-4 player network card game. Before I jumped into doing the card game. I decided to try out an a simple program which is the clients taking turns to type in their textfield.

I have a server that listens to 3 incoming client connections. once all 3 clients is being connected,

Steps

1) The first client will send the message first while the second and third client will wait for the first client to finish sending.

2) After the first client finished sending the message, it will be second client turn to send the message and the third client will wait for the second client to send finish.

3) After the third client finished sending the message, it will be third client turn to send the message and the first client will wait for the third client to send finish and (go back to step 1))

**The first client can only start typing once all 3 clients is being connected**

In my server class,I spawn a new Thread once a client is connected, I do a wait() on each time the client is being connected, I stored the thread in a arraylist as well. I have an id to keep track how many clients is currently connected. once the id reaches 3, I used notifyall() to notify all the threads and set the first position of my arraylist as my currentThread so that I can keep track which is the currentThread running.

I started 3 clients. and I typed the textfield of the first client but my server isn't receiving any messages.

class Server implements Runnable {
private List<SpawnNewThread> sntList = new ArrayList<SpawnNewThread>();
private SpawnNewThread currentThread;
private int id = 0;

[Code].....

JSF :: Enabling And Disabling ComboBox / TextBox Based On Actions

Apr 24, 2014

This is my modalPanel code:

<rich:modalPanel id="createManagedObject" moveable="false" autosized="true" width="500" rendered="true" domElementAttachment="form">
<f:facet name="header">
<h:panelGroup>
<h:outputText value="Create Managed Object"></h:outputText>
</h:panelGroup>
</f:facet>
<f:facet name="controls">
<h:outputLink onclick="#{rich:component('createManagedObject')}.hide(); return false;">

[Code] ....

As shown in the above code:

I have following components in ModalPanel:

1) ComboBox
2) Instance
3) Save and Cancel

I wanted some validation here :

For example:

- The Instance Text box and SAVE button should be disabled. When the pop up appears.
- The Instance Text BOX gets enabled only when any selection happenes in COMBO Box
- The SAVE button gets enabled only when COMBO BOX and INSTANCE TEXT BOX is filled.
- Let the CANCEL button be enabled always.

EJB / EE :: Entity For Multiple PU And Different DB?

Dec 18, 2013

I have a package (JAR_A) for entity and controller definition, for example:

entity: Entity
controller: EntityController

Then I use this jar in other projects/applications that use the entity.

I want to use the same JAR_A with different persistence unit and different database (in particular, mysql and postgresql) but when I define two persistence unit that include the same class, I have an exception.

So, I comment the other PU and compile the project.

there is a smarter way for use same package with different PU ?

How To Add Multiple OR Choices In If Statement

Jan 21, 2015

I have this very code:

if (minute > 35 && hosts < 1 && guests < 1)

In this if statement I would also like to add another two possibilities:

first would be: hosts < 1 && guests < 2
second would be: hosts < 2 && guests < 1

Is it possible to somehow add it so it can all be in included in one if statement, and it would look something like that:

if (minute > 35 && hosts < 1 && guests < 1 OR
minute > 35 && hosts < 2 && guests < 1 OR
minute > 35 && hosts < 1 && guests < 2) {}

ArrayList Through Multiple Classes?

Oct 25, 2014

I have to make a retail item class that has description, price and quantity. I then have to make a CashRegister class that calculates subtotal, tax, total and displays it (toString). I also have to make a driver class to call the methods from main. I have no clue what I am doing and what I have done does not work. I am trying to make it sort of like a cart, in the CashRegister it should ask the user to enter the description, quantity purchased and the price. Then it would send that to the arraylist of retailitem. I am having trouble using those items in my other methods and then do not know how to call those in the driver class.. So here are my classes:

public class RetailItem {
private String description;
private int quantity;
private double price; 
public RetailItem(){
description = "";
quantity = 0;

Creating Multiple Classes

Apr 25, 2014

I was trying to play around a little bit after learning creating multiple classes and stuff.However,i encountered a strange problem with reading a value from the user and then storing it in a variable.The usual way i do it is

Scanner variableName=new Scanner(System.in);
System.out.println(variableName.nextLine());

But when i trying to print the contents of the variable "variableName" the compiler throws a lot of errors .I am attaching how i have tried that out in my code

import java.util.Scanner;
class laptop{
private String modelNumber;
private boolean hasFan;
private float ramSpeed;
protected int numCores;
//private String input;

[code]....

Without the setInfo() in the laptop class the program functions as desired but i intend to ask the user if he wants to modify something and then reflect the same.

Using Multiple Selection Choices?

May 28, 2014

This program allows the user to select one of each different type of skateboard/accessories items. Then it allows the user to select as many misc items as he or she chooses. The program works fine for the single choices, but I cannot solve the latter part. I have a get method in the misc class that is trying to pull out any selection or selections that were made by the user, but it simply does nothing...

Here's my program, I have four panel classes for each skateboard type, and then I have one class that takes care of adding each panel to the content pane, and calculating the total cost of the item.

Decks Panel Class:

import java.awt.event.*;
import javax.swing.*;
// The DecksPanel class allows the user to selects a specific type of skateboard
public class DecksPanel extends JPanel
