Question

TO RAJ,
I will need this back by Monday 9:00 MST.

1.Java programmers can use class hierarchies for the purposes of inheritance. For example, given a Tree class, we could define Conifer and Deciduous sub classes that inherit from the parent Tree class as you can see here:

For this learning event, you should develop a similar class hierarchy for Pets. You can have whatever subclasses you think would be useful, but your hierarchy should have at least three levels (the top class, Pet, counts as the first level). Include variables and methods (at least one of each) for each class you design, as in the above example.

2.You have been hired as a Java programmer by Real Estates Solutions Inc. Your task is to write a Java applet for their web site that would enable customers to figure out their monthly mortgage payments.
The applet input will be the loan amount, annual percentage rate or APR, and the number of years to pay out the loan. The output will be:the monthly payment amount, the number of payments, the total paid including interest, and total interest paid.
The calculations were provided to you by a real estate agent:
•     p,loan amount or principal
•     n,number of payments = payments per year * number of years
•     i,interest per period = apr/payments per year = apr/12
•     r,monthly payment amount = principal * interest per period / (1-(1+(interest perperiod)/100)^(number of payments-1)^2)
Hint: In Java syntax the monthly payment calculation is:
r=((p(i/100))/(1-(Math.pow((1+(i/100)),(n(-1))))));
Details:
Please note that your program should accept three inputs:
1.     The loan amount,
2.     Annual percentage rate or APR, and
3.     The number of years to pay out the loan
And calculate four outputs:
1.     The monthly payment amount,
2.     Number of payments,
3.     The total paid including interest, and
4.     Total interest paid
When coding your applet, remember the following:
•     Your applet needs to extend the Applet (or JApplet) class. Of course, you need to import the appropriate applet package(s).
•     Your applet needs to have declarations for the fields, labels, components, widgets,etc. that you use in the applet.
•     There are applet methods that are called automatically by browsers (please see your textbook). Make sure you initialize (implement init()) your applet.
•     You need the code that does the calculation of the interest.
•     You need to handle the event of pressing the button. There are some examples in the book (ask your instructor for the specific pages).
•     You may use this sample code for example.
Please create an HTML page that contains the applet tag. In addition to your mortgage calculator commented Java code, you need to provide the HTML page.
Here is the Hello world Java code example to create an applet:

<Title>A Simple Program</Title>
import java.awt.*;
/**
* The HelloWorld class implements anapplet that
* simply displays "HelloWorld!".
*/
public class HelloWorld extends Applet {
public void paint(Graphics g){
// Display "Hello World!"
g.drawString("Hello world!",50, 25);
}
}

Then you would compile the class and create an HTML page called Hello.htm:

<HTML>

<HEAD>

<TITLE>A Simple Program<./TITLE>

</HEAD>

<BODY>

Here is the output of my program:
<APPLET CODE="HelloWorld.class"WIDTH="150" HEIGHT="25">

</APPLET>

</BODY>

</HTML>

Deliverable Details:
Upload the commented source code file of your calculator and the HTML file.
Please add your files.

Accepted Answer

Hi, I am glad to hear that you liked it.

The screenshot is just a sample to show you the applet working. When you open it, all fields are blank, ready to use.

The file MortgageCalculator.zip has everything you need:
MortgageCalculatorApplet.java - The source code
MortgageCalculatorApplet.class - The compiled class
MortgageCalculator.html - The page which displays the applet.
The HelloWorld Applet and the HelloWorld page (html) you provided me is just to show how to create an Applet and a HTML page to display an Applet.

So, if you are set, please don't forget to hit the accept button. Feel free to ask me more questions if you have any doubts.

Kind regards,
XXXXXX XXXXXXX.

You need to open the HTML page to show the calculator.

I need to have have an actual hierarchy. I could not post the actual example which was a hierarchy chart for pets. I need a chart for something different. I did I put in a folder and was able to see each file but cannot open them. I think something must be wrong with my computer I dont know.

So do you need a new hierarchy? Would you like to suggest one?
What do you see when you open the HTML page? An empty page?

When I open up the HTML the page it is empty with an error page that says "X errorClick for details". It says the application failed to run.

There was an error while executing the application. Click "details" for more information.

Answer

Hi, the problem is very simple to solve.... I told you before:

"Oh, please don't forget to extract ALL files to a folder BEFORE you open the HTML page, MortgageCalculator.html"

If you just double click the ZIP file and then double click on the HTML page, your ZIP program (Winrar, Winzip, whatever) will extract just the HTML page to a temporary folder, as you can see here:

Caused by: java.io.FileNotFoundException: C:\Users\JESUS\AppData\Local\Temp\Temp1_MortgageCalculator.zip

To see the applet running, you need two files: MortgageCalculator.html AND MortgageCalculatorApplet.class

You really need to extract those files before you open up the HTML page... Please follow these steps:

1. Create a new folder in the root directory (C:\)
2. Copy this file into your new folder: http://ww2.justanswer.com/uploads/fael/2009-06-30_013230_MortgageCalculator.zip
3. Double-click on the ZIP file, and select all files (hold CTRL and then press A)
4. Copy the selected files (hold CTRL and then press C)
5. Go back to the parent folder (you can press BACKSPACE)
6. Paste the files (hold CTRL and press V)
7. Open up the HTML page again.

Can you see the applet now? Let me know.

Regards,
XXXXXX XXXXXXX.

Rafael, I need an actual 3 level hirerachy chart similar to this

Java programmers can use class hierarchies for the purposes of inheritance. For example, given a Tree class, we could define Conifer and Deciduous sub classes that inherit from the parent Tree class as you can see here:

                             Tree
                        double height;
                        int numBranches;
                   public Tree cutdown ();
                   public void water ();

   Deciduous                                 Confier
int numLeaves;                            int numNeedles;
String leafColor;                           pinecone () cones;

public void setSeason (String Season);   public Pinecone getCone();

It is a 3 level chat I could not draw the lines in the example. This is what is needed.

Posted by Rafael Martins 144 days and 20 hours ago.

Answer

If Deciduous and Confier extends Tree, then this is a 2 level chart... I sent you a program with 3 levels: Machine, Computer and Laptop. What's your text book?

144 days and 20 hours ago.

Reply

Java How to program is the name of the text book. But what I sent you is what he wants the chart to look like. I apologize. I am very new at programming in java. So what type of code would I need for the example.
                  Machine

Computer                          Laptop

I really don't want to wear you out with this, because I truly apprecite your service.
