I need to create a grocery store calculator in Netbeans GUI. It should function as follows:
1. Click "Checkout"
2. Enter item price screen pops up.
3. Input item price, and store price in Item price, subtotal and display in those text fields. Also store item number in number of items and display in text field, all after you click "Ok".
4. Enter item price screen should automatically pop back up. (Loop)
5. Once you are finished with all items, when you click "Ok" or "Cancel" with nothing in the text field. It should calculate sales tax/ total sale and display both.
6. Rest button should reset to the beginning and Exit button should exit program.

The good news is my program works right now. Although I do not believe I am using the setter/getter methods correctly. More importantly I do not fully understand them. I left out the Generated code due to the length.
import java.text.NumberFormat;
import javax.swing.JOptionPane;
public class Assignment4 extends javax.swing.JFrame {
NumberFormat nF = NumberFormat.getCurrencyInstance();
private Object JoptionPane;
private double purchase; //private instance variables
private int numItems; //private instance variables
Now I want to store the image displayed in the jlabel into the database(oracle).From the above code I dont know how to get the absolute path of the images.
Create a Java Application in NetBeans with the following two classes.
1. A Java class College o Use the following data fields: College Name College City Number of Tracks Number of Students Number of Faculty Number of Staff o Implement an empty constructor o Implement a full constructor o Implement Setters and Getters (Mutators and Accessors) o Implement SetAll() method with all data members as parameters
2. Another Java class called CollegeDemo with the main() method: o In the main(): o Read the values of the fields of 3 colleges from a text file and for each create a College object. Filename: colleges.txt IT Dubai 7 200 50 20 ENG Abudhabi 4 400 60 20 SCIENCE Sharjah 3 300 40 20 First with empty constructor then uses setters. Second with full constructor (no need to use setters). Last one with empty constructor and SetAll() setter. o Display the average number of students for all the 3 colleges. o Change the value of ‘Number of Students’ in the SCIENCE College to 500, and display the average number of students again.
here my code :
public class Demo { private String name ; private String city; private String cname ;
I'm new to java and trying to learn the ropes on Netbeans!What I want to do is make a class which does the following
-Asks for and reads a first number on the command line. -Asks for and reads a second number using a JOptionPane -Asks for and reads your name using a JOptionPane
I want it to output the name and the remainder of the first number divided by the second number.
I'm new to java and have been coding for a few hours. I tried to create a calculator (Which has no GUI, just text inputs)which will let you select how to process the two integer (Add, minus, times etc.) I cant seem to get it to work. I will put in the process way such as times and have entered two integers and every time it doesn't work. Here is my code:
import java.util.*; public class Calculator { public static void main (String args[]) { int input1 = 0; int input2 = 0; int answer = 0;
Write a program that prompts the user for information about some countries, creates an object for each country, and then stores the objects in an array. After the user has entered information about all the countries, your program should print out which countries in the list have the smallest and largest area and population density. Assume the user will enter information about at least one country but that the program will not have to store more than ten countries in the array. The user will indicate that they are done entering countries by typing "DONE" for a country name. Here is an example of what your program must look like when it is executed (user input is shown bold)
Please enter the name of a country: United States Enter the area in square km and population of United States: 9827000 310000000 Please enter the name of a country: Mexico Enter the area in square km and population of Mexico: 1973000 122300000 Please enter the name of a country: Canada Enter the area in square km and population of Canada: 9985000 35160000 Please enter the name of a country: Liberia Enter the area in square km and population of Liberia: 111370 4294000 Please enter the name of a country: DONE
Liberia has the smallest area at 111370 square km. Canada has the largest area at 9985000 square km. Canada has the smallest population density at 3.521282 people per square km. Mexico has the largest population density at 61.986822 people per square km.
I don't know, I'm really confused with this Java program. I don't know how to do the main part of the program where the user inputs, array, and the output.
// Access the Scanner and ArrayList class by importing the java.util package. import java.util.Scanner;
/** Project - A Country Object * The purpose of this program is for the user to enter some information at most 10 countries. After the user has entered information about all the countries, the program should print out which countries in the list have the smallest and largest area and population density. */
public class Country { private String countryName; private int theArea; private int thePopulation; public Country(String countryName, int thePopulation, int theArea)
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" xmlns:ui="http://xmlns.jcp.org/jsf/facelets" xmlns:h="http://xmlns.jcp.org/jsf/html">
In this main class, create 5 objects of the class Menu, as defined in the table below.
Name amount of calories cooking time price per person number of drinks
Fufu and Groundnut Soup 564.65 2515.572 Red Red 345 12 9.980 Rice and Beef Stew 560.4 1512.651 Ga Kenkey and Fish 780 10 10.15 1 Banku and Tilapia 450.4 35 25.17 2
Exercise d In your main class create an array of length 5, and store the 5 objects (Exercise c) into the array. You can use any name for your array.
From the array, use a loop to: Print the details of all the objects using the method you defined in Exercise b.
Exercise e Use another loop to: -Print only the name and cooking time of all the dishes that take less than 30 minutes to cook. Hint: you may use the getter methods for the name and cooking time attributes, and then, print these values (name, cooking time).
Exercise f Use another loop to : -Calculate and print the total price of all the objects (in the array). -Calculate the total price of all the objects with VAT included for each dish (VAT rate is 17.5%).
Submission -Create a folder with your index number as its name. -Copy your Java Project folder into the created folder. -Print a hard copy of your classes. -Submit both soft copy and hard copy of your project
I am new to java and I am creating a system that will ask the user to create a file that will store to a text file, Once the user created the file I have a class that will let the user input the subject name that has been created, However, I keep on getting this java.util.nosuchelementexception.Here's my code:
public void display_by_name() { String id, name,total; String key[]=new String[30]; String value[]=new String[30]; int i=0;
I am trying to create a program in NetBeans GUI builder and I am having trouble creating the 2D array. Here is what I have come up with so far:
private void enterButtonActionPerformed(java.awt.event.ActionEvent evt) { // TODO add your handling code here: double time = 0; try{ time = Double.parseDouble(timeText.getText());
[Code] ....
Right now it is printing what i need but I need to separate columns, not rows.
Currently the while near the end is not working in netbeans. It is saying illegal start of type. This whole section was working before when it was within the public static void method. I moved it to a separate class to try and clear up a, static variable problem. My question is can i fix it to keep it structured this way. Or do I have to put it back into the main method and try to work out the static variable problem a different way.
public class InventoryProgram { double[] dvdprice; // defines variables int[] dvdnum; int[] dvdstock; String[] dvdnames; int count; double total;
In the class below I'm trying to create a class that will accept dates in various formats and create a range. The first constructor is easy because I send it the begin date and end date as Date objects. Now I want to send a month(and year) in a constructor and derive the begin and end dates from it. In my constructor that accepts the month/year I need to put the this(startDate, endDate) at the top to be allowed, but the parameters are not built yet.
package com.scg.athrowaway; import java.util.Calendar; import java.util.Date; public class DateRange { private Date startDate; private Date endDate;
I'm working on a University project creating a simple game using Netbeans but I'm totally stuck. I've created a number of classes to perform various methods, such as throwing back formatted text but I can't get them to work from within a Swing GUI created in Netbeans.
The Main method simply creates an instance of another class called Game which then itself creates instances of a number of other classes (textEngine, timer) and also a Swing GUI Class. The GUI appears on screen ok and I've been able to get methods working inside the GUI such as changing pictures and text when clicking a button. But I CANT get the GUI class to recognise the instances of the other classes or access their methods. I've created an instance of the TextEngine class called tEng. So I type this code in the GUI class:
textField.setText(tEng.getPhrase(2));
getPhrase() returns a String based on the number passed in the argument. But Netbeans reports an error that tEng is not recognised as a symbol despit it being a member of the same package. Creating the instance of the class within the GUI class likewise fails:
This is a stopwatch program. Somehow, the run method in the displayUpdater does not get called. Overall, the program should have a start button and when the user clicks start, the button changes into a timer. My timer doesn't count here because the run method is not called.
import java.awt.event.ActionEvent; import javax.swing.SwingUtilities; public class StopWatchNew extends javax.swing.JFrame { /** * Creates new form StopWatchNew */ public StopWatchNew() { initComponents();
find a way to make all my clases in one single tab and not like this: URL....
because at the end of the exam, we have to paste the whole code (as one) in a specified web page, which instantly shows us the result. We need the whole code to be in just one page (like back in C++).
I want to connect netbeans to netlogo. I have a class: NetLogoConnection I want to call the class when I click on OK btn in my GUI. The codes are as following:
XML Code: import org.nlogo.app.App; public class NetLogoConnection { public static void main(String[] argv) { App.main(argv); try { java.awt.EventQueue.invokeAndWait( new Runnable() { public void run() {
I'm running Netbeans 8.0 and attempting to use Apache POI to read various .xlsx files.
Currently, I'm getting a java.io.FileNotFoundException.
I'm using a Mac. What is the correct way to list the file path for my files in Netbeans? Also, is it possible to add the files to my actual project and access them inside the project?
I are having some trouble with our quiz that we made in NetBeans. The problem we have is that when we press play the question opens in a new window ( if we klick this button imgur: the simple image sharer this happens imgur: the simple image sharer but we want it to look like this imgur: the simple image sharer when we press the button). the code we are using for the button is imgur: the simple image sharer.
I'm trying to create a GUI interface in Netbeans that calculates a phone bill.
I created a GUI interface that input: - Account Name. - Account Number. - Number of Minutes the phone was used. (with a textarea so the user input the minutes) - 2 JRadioButtoms so the user can chose the regular or premium service. - Amount Due (+10% taxes) (also with a textarea) - Clear/Enter/Result/Done Buttoms
And I need to output: - Account Name. - Account Number. - Number of Minutes. - Taxes - Total Amount Due.
I have a couple of math formulas I have to add them to output the above however I'm new to java so I don't know which code to use.

[Code] .....
When I'm trying to compile it with netbeans i get these errors and i just can't figure why is that!

I want to know that how can i use break points in net beans 8. I'm able to put break point by clicking at the line but don't know how to use it..Actually i'm getting wrong output of my code and i want to know my line by line execution of the code so i can get better idea of where is my code going from one line to other. I have used break point in micro soft visual studio2010 and that was easy after puting break point run the project then f11 to get line by line execution...I want to know any method exist in java net beans (i'm doing GUI swing controls)...
When I click on "Clean and Build" NetBeans generates a .jar file and inside the folder "dist" it add a directory called "lib" with all the java libraries used to implement the program. I would like to achieve with this IDE an unique .jar file that includes everything you need such as Eclipse does by default. Is it possible?
my IDE doesn't seem to recognize that my program is a Swing app.I get the following error message when I run the app: "jtabledemo.JTableDemo class wasn't found in JTableDemo project."It compiles successfully though.Here is the code verbatim:
