How To Create A Menu
May 12, 2014
I'm trying to create a GUI java application.
I want a menu with buttons that looks like this:
Button 1: Start
Button 2: Help
Button 3: About Me
If you press one of the buttons you will get to another frame with new buttons, new labels and so on.
Next step for instance if you press button 1, I'd like my program to get this frame:
Different alternatives, and a text field with a button. One commando leads to one new JFrame with new buttons, text fields and so on.

I'm having some difficulty with my bank account project. I'm supposed to create a menu where the user can create a new account, withdraw, deposit, view their balance, and exit. There's issues with the account creation.
Here's my necessitated class below: BankAccount, TestBankAccount, SavingsAccount, CurrentAccount, and Bank

So for the last few weeks I have been working on a Java project for school. I see the light at the end of the tunnel, but I have run into some speed bumps with my main class. It was working fine, but I was pulling an all night and I deleted some of my code by mistake.Now I am not seeing what is exactly wrong. Anyways, the project was to create an address book complete with a menu system.
Here are all of my classes:
import java.util.ArrayList;
/**
* A model of an address book which keeps track of contacts.
* An address book object should keep track of the concept of a current contact (think index).
* You must use an ArrayList for your implementation.
*/
public class AddressBook {
Contact contact = new Contact();
[code]....

I am working with Netbeans 8.0 and JSF2.2. I am trying to create a web site that has a common header, footer, and menu. The only part that would be dynamic is the content. So here goes...
1) I need a common template that has 4 parts, Header, Footer, Menu, Content
2) The header, footer and menu are to be in a separate files of which are called from the main template
3) The content will change based on the menu item changed
4) The menu has to change the content section only
I know how to do this in HTML but I am trying to set up some thing in JSF to learn more on JSF pages. All I am looking for is an example that I can follow along with having the multiple pages as well having the menu change the content (I have done a ton of internet searching but nothing really fits the bill).
This is the code I have currently.
Index (Main Template)
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"

I want to read json file as follow;
{
"M": {
"row": [
{
"col1": "c00"
},
{
"col1": "c10",
"col2": "c11"
},
{
"col1": "c20",
"col2": "c21",
"col3": "c22"
}
]
}
}
Next to reading I need to assign to two dimensional array, but without giving "col1","col2","col3" a lot.
The array is for example, Array[3][] = {{"c00"},{"c10","c11"},{"c20","c21","c22"}};

I have a GUI with a menu to do various options. However I want to change that menu to use buttons instead. I'm working with JSwing components and I'm a little familiar with the JButton function, but I don't know how to convert the menu to a button. I think I'll have to remove the menu completely..anyway I tried to start with the file menu but the compiler says no suitable method found for setForeground(javax.swing.JMenu). Why is it giving me an error related to JMenu when I'm using Jbutton objects? Can I not use JButton objects inside a menubar scope? I'll bold the area it highlighted:
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

I am working on implementing a stack using a linked list. Programming the stack operations (push, pop, isEmpty, etc.) was easy but my directions were to provide the user with a menu to choose the operation that he/she wishes to perform. I am new to JFrames/Menus so how to make the stack operations available in a menu.

How would I change items in the main menu (top of screen) that has the app's name on it (e.g. Firefox)? I've used :
System.setProperty("apple.laf.useScreenMenuBar", "true");
And it works, but how would I change things like "About [thisapp]" and make it execute a certain method?

2 problems with this code:
How do I code this so that after the user has added to the arraylist 'theFruit' if they then press 'V' to view all fruit it includes the default fruit as well as the fruit they've added?
Also in the method 'AddFruit' it only allows me to add 2 fruit before printing. Why is this?
import java.util.ArrayList;
import java.util.Scanner;
public class StkOv {
public static void main(String[] args) {
TheMenu();

I cannot use menu selection 4 5 6 7 8 9 10 ... Why NO_EXIT has been declared and used in defining the contents of the map array, rather than just directly using the value 99999 in the map array definition
I don't understand map[][], objectName[] and objectLocation[]
package Assignment;
import java.util.Scanner;
public class GameWorld
{
// the map array holds details on which paths lead to which other rooms. NO_EXIT indicates no valid exit.
// each element holds the details of all paths leading out from a single-room in the order n ,e, s, w, ne, se, sw, nw
private final int NO_EXIT = 99999; // indicates that there is no exit in that direction
private int map[][] ={{NO_EXIT,NO_EXIT,NO_EXIT,1},{2,0,NO_EXIT,NO_EXIT},{NO_EXIT,3,1,NO_EXIT},{NO_EXIT,NO_EXIT,NO_EXIT,2}};

So i have a problem i want to make a menu that allows you to press 1 and then make lets say a Car,
The code would look like
Car car = new Car();
And then add to my list
cars.add(car);
If in my menu the person presses 1 again, will they add another car or will it override it
Also: how can i make a menu that doesnt allow you to press option 5 (something that requires you something that should be registered in other options ), until you registered them?

I am tasked with creating several JPanels each of which has a title centered at the top. As such I have created parent panel that each panel extends. However, I am uncertain as to whether drawing the string on the panel or using a JLabel is the best solution. The panels might allow dynamic resizing...

Is there a way to connect the popupmenu to the right Object (JFrame).
(Something like SwingUtilities.getWindowAncestor(popupmenu)
I've created 2 JFrames each with the same MouseClass. When you click on the RMB a pop menu is shown with a background item. When clicked on the background item only the last created JFrame changes his background.
Below is my simplified code. I'm probably not thinking like a good OO'er.
static JFrame frame;
static JPopupMenu popupMenu;
public static void main(String[] args) {
popupInit();
frame = new JFrame();
frame.setBounds(0, 0, 230, 230);

I have a question and wasn't able to find what I needed through the search. I am currently using Netbeans 8.0 and working on a desktop app. I have a main GUI file where I am going to add a menu item that can be clicked to open up an "About" Dialog box. The problem is, I don't know how to do this
The file are...
MainGui.java
About.java
How would I go about opening the About.java when clicking on a menu item? I tried using...
new About();
About.setVisible(true);
But this just gave a compilation error.
