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:
the analog clock dese not move put it work when i run the program and the the buttoms dose not work i do not why how i can use the menu alarm to change the alarm time this my code run it.
I am new to OOP, i am not sure if this is the correct approach or not. Write a class named CreditCard that has (at least) the following member variables:
- name. A String that holds the card holder's name. - cardNumber. A field that holds the credit card number. - balance. A double that stores the current credit card balance. - spendingLimit. A double that stores the spending limit of the card holder. - Bonus: additional fields that you can think of.
In addition, the class should have the following member functions:
- Constructor. The constructor should accept the card holder's name and card number and assign these values to the object's corresponding member variables. The constructor should initialize the spending limit to $2,000 and the balance to $0. - Accessors. Appropriate accessor functions should be created to allow values to be retrieved from an object's member variables. - purchase. This function should add the amount specified as a parameter to the balance member variable each time it is called. - increaseSpendingLimit. This function should add 500 to the spendingLimit member variable each time it is called. - payBill. This function should reset the balance to 0. - Input validation: Whenever a credit card number is modified, verify that it is of reasonable length.
Demonstrate the class in a program that creates a CreditCard object and allows the user to change and view the state of the credit card with a menu driven program.
View Card Information.
- Purchase an Item: ask the user the purchase amount and increase the card balance accordingly. - Pay Bill: call payBill method to set the balance to 0. - Increase Spending Limit: ask the user how much the spending limit should be, and call the increaseSpendingLimit function the appropriate number of times.

import java.io.*; import java.util.Scanner; public class CreditCard { Scanner input = new Scanner(System.in); //data members private String holderName; private int cardNumber; private int accountBalance; private double spendingLimit;
I am having problem with the JRadio Buttons to change the font color in my code. What needs to be done? Also if I were to connect this GUI to another GUI and save font colors, how would I go about that?
I'm making a game of checkers for my A2 Computing coursework which is due in within a week. I have completely finished the game, and only thing I have left to do is connect the two JPanels together via a CardLayout that I have made. However I am unsure how to do so
I have kept the code I am displaying to a minimal, hence I have removed all the action listeners for my buttons, anyway the problem I have is that, I would like it so that when the user clicks on the 'Multiplayer' button which is the array button ourButtons[1], it will then transition into my main game screen so that the user can then play a game of checkers.
Here is the main important GUI from my CheckerBoard class:
import java.awt.*; import java.awt.event.*; import javax.swing.*; public class CheckerBoard extends JPanel implements ActionListener, MouseListener { // Main routine that opens an Applet that shows a CheckerBoard public static void main(String[] args) { new CLayout();
I want to create a dropdown menu with contents from a database. You can see my Code in the attachment. It does not work, but why? I have a dropdown-symbol, but no contents.
ok so I am trying to create a movie rental database. I want to show a list of movies, customers, and rentals. my problem is that I cant run everything but I keep getting the following error :
ERROR: Table/View 'MOVIES' does not exist.
Here is my code
import java.sql.*; import java.util.Scanner; public class MovieRentalDB { public static void main(String[] args)
[code]....
the program runs but I keep getting that error. I know my code is also not complete but I will do the rest once I figure out why my tables are not creating
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.
I am making an edit page and I want to populate my drop down menu with things that were already selected. For example, if i want i click to edit my favorite food it will be populated with the one the user previously selected. How do i go about doing this? [URL] ....
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}};
//construct and populate the Time menu Menu mnuTime = new Menu("Time", true); mnuBar.add(mnuTime); MenuItem mnuCurrentTime = new MenuItem("CurrentTime"); mnuTime.add(mnuCurrentTime);

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 beginner in java and i am making an application in which i want to display menu for 3 different types of users. like when we login i want to check which type of user is this and which menu to show them. for ex. if there is a employee the menu bar has a dropdown which shows activities like fill nomination, see details etc. if it privileged user he is shown a diff menu and if its the admin the dropdown shows some different activities. i want to make it through simple jsp and servlet. i have a table in data base which has types of user predefined with an id how to display that menu according to a specific user.
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.
I am currently tackling homework for a small I/O-program with console input.Right now, only the part when you enter "E" or "e" on the console is implemented and the issue I am trying to tackle is described in the comment starting at line 38:
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
