I am trying to create a basic graphical user interface for sequence translation (including a JTextField for the description of a sequence and status of function button pressed e.g. “simple” translation and input and output TextFields). This involves a number of different class files. I cannot get my user interface to do what I want and I think I have problems with my "actionPerformed" method. How the code should be linked together?
public void actionPerformed(ActionEvent event) {
try {
// Get the description, content and result
String d = tool.getDescription();
String input = tool.getInputText();
Stringr = translation.getResult();

I am new a creating GUIs and am not quite sure how to correctly make one. I have done the inheritance parts, and created two extra appliances: a washer and dryer. Now Creating the GUI ....
Here are the instructions to my project.
Introduction to GUIs (+ some inheritance)
For this assignment, you are going to create a user interface that interacts with the setters and getters of some classes that you will create.
First, create an abstract class called Appliance. This abstract class should have two attributes (dealing with household appliances) and two abstract methods called turnOn() and turnOff(). These methods should return void.
Then, create two subclasses of Appliance that represent household appliances (like a Refrigerator or Stove ((don't use those!))). These subclasses should have two attributes that are specific to the various appliance. Each subclass should implement the turnOn() and turnOff() methods. These methods should print to the command line some information about the appliance as it turns on and off.
Now, the fun part! Create a GUI interface!
Your window should have two panels: one for each appliance subclass. Each panel should have 4 textboxes (with appropriate labels) to receive/display information that correspond to the 4 attributes (2 from Appliance and 2 from the subclass) for each subclass.You also need 2 buttons on each panel: A Get button and a Set button.
When the Get button is pressed, the text boxes should be filled with the information from the instantiated object of the appropriate subclass. When the Set button is pressed, the object should then contain the information contained that the user has altered.
In your main method, you should create an object of each subclass, and prefill it with information (either using the constructor or the setters), then display your GUI. You should now be able to get and set the information for your objects from the GUI.
At least one of your attributes for each subclass should be numeric
Note that you will need to handle incorrectly formatted input (You can use exception handling to do this if you want to. Wrapper classes also will work)
If there is text in the boxes when the "Get" button is pressed, it should be overwritten by what is in the object. Remember that these two panels should both be on screen at the same time.
You don't need 2 different windows, one window: 2 panels.
I'm currently new to java and I would just like to ask if Socket is sufficient for this file transfer app I'm planning to work on.
The specs are as follows:
~ Move/Copy Files of selected folder/s to a single folder(consolidating them) within the same machine and Network
~ File type will be specified on GUI and those specified will be the ones transferred
~ option to choose Move or Copy of files
~ ability to create/select folder of transfer destination
Here is an draft of what the GUI will look like.
I have a jsp form that has a drop down option for a user to select. I would like to know how to have a pre-selected option that has been retrieved from my database or provide a default option if none has been selected by the user. My form allows a user to update a record in my database and what I need to achieve is when a user is updating an existing record they do not have to touch the drop down box if the do not need to change that option.
Here is my current form below form method
="POST" action='UserController?action=edit&albumId=${album.albumId}' name="frmAddAlbum">
<label for="album id">Format : </label>
<select name="action" selected=<c:out value="${album.format}" /> >
<option value="listUser">CD</option>
<option value="listUser">Tape</option>
<option value="listUser">MP3</option>
<option value="listUser">VINYL</option>
</select>

I am trying to have a user select from a printed out array list, instead of having the user type in the "bill type" each time there is a bill to avoid user error as much as possible. For example I would like to have it print out like this:
"Select bill type from list:
1. Rent
2. Car
3. etc..."
and I would like the user to choose a number and not type in the "bill type". I don't want to use "Switch case" because it would need to be an expanding and I don't think "switch case" can do that.
Here is the code:
package homebudget;
class Spending
{
//Do i need a totalAmount variable?
String type;
double amount;
int year, month, day;
public Spending()
[Code] ....
case 2:
//Give option to enter a new expense or pick from list.
//How to do this? If Statement that doesn't list duplicates, or a while search?
resp = JOptionPane.showInputDialog("Enter the type of expense:");
type = resp;
resp = JOptionPane.showInputDialog("Enter the amount of the expense:");
amount = Double.parseDouble(resp);

i am trying to write a program in which the user will select a text file(which contains information that the graphical output will be based). I have successfully set up my file chooser however when i select the text file,i do not get any graphical out put. please see attached .zip file for code.

I am new to Java and have read books, the Java docs, and searched the Internet for my problem to no avail. I have an Array of objects that contains strings. How can I get the object's strings to print in a list so that the user can select that object to manipulate its attributes? For example, the user can select "Guitar 1" from a list and manipulate its attributes like tuning it, playing it, etc. I have a class called Instruments and created 10 guitar objects.Here is the code:
Instrument [] guitar = new Instrument[10];
for (int i = 0; i < 10; i++) {
guitar[0] = new Instrument("Guitar 1");
guitar[1] = new Instrument("Guitar 2");

2.Check the Vehicle...Assume that vehicles are going through a two-way traffic intersection. There are three types of vehicles: car, motor bikes and trucks. Generate a series of 10 random integers, between 1 and 3, inclusive. The numbers represent the type of vehicle as stated below:
NumberVehicle Category
1 Car
2 Motor bikes
3 Trucks
Write a program, using a for loop, to count how many vehicles going through the traffic intersection are cars, motor bikes and trucks. Then, the program should print out the numbers for each vehicle category. There is no user input for this program.
What I'm trying to do is show a loginscreen. After logging in it should show another contentpane with actual content.
This is my main class:
public class Project extends JFrame
{
public static void main(String[] args)
{
JFrame frame = new Project ();
JPanel paneel = new Paneel ();
frame.setSize (800, 600);
[Code] ....
The compiler gives me an error when I try to refer to "frame". What I've tried to do is refer to frame by using
Project.frame but it still gives me the same error. The compiler shows the message that it cannot find "frame" in class Project, but that's exactly where it is!
Is there a simple way to make this work? I've read about threads and loops but they don't seem the most basic solution. Maybe there's a way to get the current frame so I can use that?
I have a TxT file with the next content:

The output console should look like :
Cars : Lamborghini 10

-A customer has a name, an email address and a list of supplements which they are interested in.
-A paying customer has a payment method and a list of associate customers whom they also pay for.
-An associate customer is a customer whose subscription is paid for by a specified paying customer.
-A payment method could be by a specified credit card or direct debit from a specified bank account.
-A supplement has a name and a weekly cost.
The magazine also has a weekly cost for the main part.Each week, each customer gets an email telling them their magazine is ready to look at and listing the supplements that they currently subscribe to.Each month, each paying customer gets an email telling them how much is being charged to their card or account for the month and itemizing the cost by supplements for them and any of their associate customers.Design and implement enough functionality in the classes to allow the operation of the following test program (which you also design, implement, test, and document):The client program should do the following:
a) construct a magazine with an array of 3-4 supplements with made-up details built in to the program (Alternatively, get input from the user using the Java Scanner class),
b) construct an array of 5-6 different customers of various types with made-up details built in to the program (Alternatively, get input from the user using the Java Scanner class),
c) view details of all customers stored in the array,
d) print out the text of all the emails for all customers for one week of magazines,
e) print out the text for the end of month emails for the paying customers,
f) add a new customer to the magazine service,
g) remove an existing customer from the magazine service.
Display enough information during the running of the program to allow checking of its operation.

I'm basically trying to make it so that when the user enters tnum, tnum2, tnum3 and tnum4, their answer turns to the variable which has to be either true or false to make the boolean work. I don't know really how to do this. I want to make it so that if they enter yes, then that makes the boolean true and the numbers will multiply and create the answer variable. If they enter no then the boolean is false and it moves onto the next if statement. How can I do this?
You have a store that sells the following items:
Shoes $50.00
T-shirts $30.00
Shorts $75.00
Caps $15.00
Jackets $100.00
Your sales associates need a program where they can enter customer information and calculate the customer's total bill. When the sales associate enters the program they should be presented with this main menu.
Enter customer information
Display Total Bill
Quit
If the sales associate selects option 1, the program should allow the sales associate to input their name, address, and e-mail address. Your program should then display this customer information to the screen with a message that the customer has been added to the customer list.
If the sales associate selects option 2, the program should ask the sales associate for the customer's name, product that the customer is purchasing, the quantity, and the price of the product. The total bill will then be displayed to the screen and should include the following:
- The customer's name.
- The product the customer is purchasing, the quantity, and total cost
- The amount of tax 8%
- The total cost with tax.
Example Total Bill Output:
John Doe
Product Purchased Quantity Total Cost
Shoes 2 $100.00
Tax 8%: $8.00
Total Cost: $108.00
HOW DO I WIITE IT
i need to create a program that asks the user for an array and then asks the user to fill in the slots of the array but i have to do it in a method
