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 trying to create a JAR in NetBeans, but I get messages.:

Netbeans version = 7.0.1
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 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.

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.

I am new to Java, I am using Netbeans to create a simple GUI with one button that just says "play". I want this to play an mp3 file i specify. I have found code to simply play a WAV which works great.There is lots of information on the net about playing an mp3 but it's all long an complicated. There must be a simple way to just have java play an mp3 file.

To get starated I now want to create a simple JFrame application that works in the following way. On the opening screen I want to present 4 buttons. Based on the selection I want the JFrame to change layout and components so that the same JFrame behind the scenes contains 5 layouts but only one visible at any time. What is the best way to accomplish this? Or should I do this in another way using multiple JFrames or similar?
My assignment was to create a simple form that demonstrates the use of the factory and singleton design patterns. "Use the Factory pattern to ensure that each form input consists of a text label and a textfield. Use the Singleton pattern for the submit button. When the submit button is clicked, a pop-up should show all the information that was typed into all of the form fields."
I used JFrame to create the form without the design patterns and I although I get the desired result, I'm not quite sure how I can integrate the design patterns into the code I wrote. The example I have to go off uses shapes, not text fields so I think that's why I'm not quite clear on how to approach this.
Here's my code so far:
import javax.swing.event.*;
import javax.swing.*;
import java.awt.*;

So I'm trying to create a simple user database that I could eventually turn into a login system. I created a simple table on MySQL with a name and address for the sake of simplicity. I tried to create simple statement inside my main method that would connect to my MySQL server and when I run my program I get a ClassNotFoundException from "org.gjt.mm.mysql.Driver"..Here is what I have in my main method thus far:
public static void main(String args[]) {
try {
Class.forName("org.gjt.mm.mysql.Driver"); //Load the driver
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/data", "root", ""); //Connect

How to create object for "class B" and call the "function_B" from other different class D where class D has no connection with class A? Here is my program.
public class A(){
void print(){}
}
class B{
void function_B(){}
}
class C{
void function_C(){}
}
Here, A, B, C are in the same package. But class D is in different package.
Design a class named Person and its two subclasses named Student and Employee. Make Faculty and Staff subclasses of Employee. There is also a MyDate class as explained below. A person has a name, address, phone number, and email address. A student has a status (freshman, sophomore, junior, or senior). Define the status as an integer which can have the value 0 (for "Freshman"),
1 (for "Sophomore"),
2 (for "Junior"), and
3 (for "Senior"),
but don't allow the status to be set to any other values. An employee has an office, salary, and dateHired. The dateHired is a MyDate field, which contains the fields: year, month, and day. The MyDate class does not explicitly inherit from any class, and it should have a no-arg constructor that sets the year, month, and day to the current year, month, and day. The MyDate class should also have a three-argument constructor that gets three int arguments for the year, month and day to set the year, month and day.
A faculty member has office hours and a rank. Define the rank as a String (for values like "Professor" or "Instructor"). A staff member has a title, which is also a String. Use data types for the fields as specified, or where one is not specified, use a data type that is appropriate for the particular field. Write a test program called TestEveryone.java that creates a Person, Student, Employee, Faculty, and Staff object, and invoke their toString() method (you don't need to call the objects' toString() method explicitly).
Note: Your MyDate.java class is the object class that your dateHired field is created from in the Employee.java class.
Do not use the Person, Employee or Faculty classes defined on pages 383 and 384 of the book. Create new ones.Here is the code I have so far concerning the employee and MyDate.
public class Employee extends Person {
private String office;
private double salary;
//private MyDate dateHired;
//7 argument constructor for employee
public Employee(String name, String phoneNumber, String email, String address, String office, double salary /*MyDate dateHired*/) {
super(name, phoneNumber, email, address);

The assignment is to create a SmartString class that implements a SmartStringInterface class (created by professor) and implements a few methods. We are basically taking a string and then taking various substrings and inserting, deleting them and undoing changes as well. Here are the methods in the interface to use along with the parameters.
public interface SmartStringInterface {
public void insert(int pos, String sstring);
public void delete(int pos, int count);
public void undo();
public String toString();
The Undo is supposed to be able to be called multiple times (to be tested using a driver program that we must create) but the part that's got me is that the changes are only supposed to be stored. Currently, I am storing the "new" string after each change onto a stack, so that undo can just pop off the stack and it will revert to the previous string. Professor said that was wrong, so I don't know how to do it. Here is what I have so far (some of the code we have is using default StackADT stuff from our book, so if you need that I can post as well. You can see in the undo method where I currently save the string. We can use multiple stacks if needed, but the less the better. Must use at least 1. The exception code is already coded for us in another file also. I am only having to code these methods and the driver to test.
import java.util.Arrays;
public class ArrayStack<T> implements StackADT<T>
private final static int DEFAULT_CAPACITY = 100
private int top;
private T[] stack;

I'm new to Java and I have an assignment to create a Sphere class that will allow you to create Sphere objects using the code below. Then create a program called SphereTester that prompts the user for the radii of two spheres in meters. The program should display which sphere is larger and by how many cubic meters and display only four digits after the decimal point. I have the sphere class given to us for the assignment which is this:

View Replies View RelatedI'm trying to get to grips with the AndEngine, so I've recently gotten hold of their Cookbook, but there's a section that's confusing. I'm using the Eclipse IDE with the section is asking that I create two inner classes to an ObjectFactory class. I'm not sure if what it wants me to do is doable in java or specifically in Eclipse. This is the section of code the book is asking me to create.
Java Code:
package com.example.helloworld;
public class ObjectFactory {
public static LargeObject createLargeObject(final int pX, final in pY){
return new LargeObject(pX,pY);
}
public static SmallObject createLargeObject(final int pX, final in pY){
return new SmallObject(pX,pY);
}
} mh_sh_highlight_all('java');
Now this is returning errors that I should declare these two as individual classes, but I feel like I am missing something. Earlier the book asks you to create this BaseObject class.
Java Code:
package com.example.helloworld;
public class BaseObject {
@SuppressWarnings("unused")
private int mX;
@SuppressWarnings("unused")
private int mY;
[code]...
It then mentions that the two classes LargeObject and SmallObject are inner classes of BaseObject and extends this class. The ObjectFactory class is meant to determine which subtype of the base class that needs, as well as define the objects properties.
I want to create a class that converts currency. I stored 2 conversion rate as constant (final) variables. In the main method, I ask the user to enter the amount in US dollars that they want to convert. Then I ask the user to enter the currencyType ("Bitcoin" or "Chuck E Cheese").
However I am stuck in the while loop:
I want to use a while loop that basically does this: If the user entered anything else ( not Bitcoin or Chuck E Chesse), then tell the user to try again, and keep reading Strings until they enter a correct currency type. If the user 3 consecutive incorrect currency types, then exit the program.
Take a look at what I have so far.. when I run the program it does not quite do what I want it to do Also, there's something wrong with one of my if statements and I want to figure out how to fix it.
Java Code:
import java.util.Scanner;
public class CurrencyConverter
{
public static void main(String[] args)
{
System.out.println("----------------------------------");
System.out.println(" Currency Converter");
System.out.println("----------------------------------");
