Customer Question

Develop a car loan payment calculator. Design a GUI to enter price of car, down payment, interest rate, and length of loan in years. Your bank only offers 3 interest rates 5%, 10%, and 12% based on credit rating. Use grouped radio buttons to select between great credit (5% interest), average credit (10% interest), and poor credit ( 12% interest). Monthly payment should be calculated by the application.

Hi,

About your other assignment, I can take a look at it if you wish.
Actually, I'm not familiar with NetBeans.

I prefer Eclipse. So it can take a while. When you need it done?

Hi,

I never have done this GUI and the professor is not going to go through this material. I read the book and stil have not gotten it to work. Thats why I still have not purchase this. I was wondering if you could tell me what to do step by step. I need to know how to do this cause I will have to explain every step I took to get my project working.

Customer replied 1459 days and 5 hours ago.

I also want to know if you could do my other assignments listed. I have this one and another GUI application that I have to work on.Write an application that uses the GeneralPath to draw a large arrow. Fill your arrow with a randomly generated color. Each time your application runs, the color of your arrow will be randomly generated. Draw multiple copies of the message “Which way?” 10 times. Each copy of the message should be in a random color, font, and location. Hint: Refer to your book for examples of using random with drawing graphics. Also check out the index for use of Random in earlier chapters.

HiCustomer

Let's do the following: I will put some nice comments in the CarLoanPaymentCalculator Project, explaining everything.

After you take a look and understand completely the code you will Accept this answer. Then I will start the other question, writing the code with some nice comments too.

Customer replied 1459 days and 3 hours ago.

HiCustomer let's start to develop our solution, step by step.

First, we need to create a new Java Project in NetBeans.

  1. Open the NetBeans IDE (6.0 or later) and click in the File menu, New Project.
  2. Select the Java in Categories, and then select Java Application in Project.
  3. Click Next.
  4. In Project Name, type CarLoanPaymentCalculator.
  5. Click Finish.
  6. You will see your project in the Projects panel. Go to Source Packages. All source files of your project are stored in this folder.
  7. Select the Main.java. We need to change its name. Press the F2 key. Type CarLoanPaymentCalculator (just like the project's name). Press the RETURN key. As we are changing the project structure, a refactoring window is displayed. For now just click on the Refactor button;
  8. Now we are ready to begin.


Here is the NetBeans project for your assignment.

This is the complete project (use it as a reference).

I
advise you to open another instance of the NetBeans IDE. You should
keep one for your project and one for my project. Look at my code while
you're developing yours.

To open my project, extract the folder and open it at NetBeans as a project:

1. File, Open Project
2. Locate the extracted folder
3. Select the folder (click once)
4. Click in the button Open Project
5. Go to Source Packages
6. Open the CarLoanPaymentCalculator class

Try to follow my instructions and you gonna make it.

Let me know if you need further assistance.

Customer replied 1458 days and 3 hours ago.

thank you very much will purchase it and can u look at my other assignments. It did work.

Customer replied 1458 days and 3 hours ago.

with the other assignments i also need to know how you did it.

Picture
Expert:  Rafael Martins replied 1458 days and 3 hours ago.

Hi,

Glad that everything worked.

What assignments you need more information?

Customer replied 1458 days and 3 hours ago.

There are three other assignments that I need help on if you could take a look at them please. If you could help can you also show me how you did it step by step.

Using the NetBeans GUI Builder implement a GUI that contains 2 buttons with labels “Time” and “Quit”. The GUI also has a text area for displaying the time. You are only creating the GUI. The buttons do not have to be functional.

Write 1 page essay that explains how you would provide functionality to this GUI if the application displays the current time when the “Time” button is clicked and exits the application when the “Quit” button is clicked. You should discuss how event handling works. Discuss any challenges you encountered developing the GUI using NetBeans GUI Builder.

2.

Write an application that uses the GeneralPath to draw a large arrow. Fill your arrow with a randomly generated color. Each time your application runs, the color of your arrow will be randomly generated. Draw multiple copies of the message “Which way?” 10 times. Each copy of the message should be in a random color, font, and location. Hint: Refer to your book for examples of using random with drawing graphics. Also check out the index for use of Random in earlier chapters.

In the text area of the discussion board discuss, write an essay that describes any challenges you had while completing this assignment. When you respond to your classmates, comment on any differences you see from their coded solutions and yours.

3.

Using Graphics and Graphics2D, create a neon sign for your business logo. Create your logo to include a shape and the name of your business. The logo should flash off and on continuously. You may get as creative as you wish with your logo.

Investigate using a delay to draw and then redraw your logo so that it behaves like a neon sign.

Hi,

I saw that you have posted earlier questions 1 and 2.
You must relist this questions to enable me to work on them.

Question 3 I did not find.
If you are posting for the first time, please put it in a new question.

Can I close this question (about the calculator) ?

Thank you.
