- This assignment is comprised of modifying your program which will calculate a monthly
amoritzed amount (e.g. a house mortgage). For this program, you are to add the logic to
prompt the user if they wish to enter the data again, then loop if they enter a "y" value;
otherwise perform the calcualtions and the error checking as in the previous program. The behavior
and layout of this program should be as in the example below. Total points for
this assignment will be 50 points. This assignment is due on or before
Tue, Mar 5.
All objects and techniques necessary for this assignment have been (or will be) covered
in class. The program should look and function as follows:
Enter loan amount: 100000
Enter rate: 6
Enter number years: 30
The monthly payment is: $599.55
Would you like to calculate again (y/n): y // note color is for emphasis
Enter loan amount: -100000
Enter rate: 6
Enter number years: 30
You must enter positive numeric data!
Would you like to calculate again (y/n): n // note color is for emphasis
- The formula to use for this assignment should be as follows:
- You must set the names of all objects/variables included in your
program to have meaningful names with correct naming conventions.
- You should refer to the programming guidelines and
follow all guidelines presented there. Failure to adhere to any of the assignment
specifications/programming guidelines will result in loss of points.
- Make sure to keep a copy of the source code that you turn in.
- Please feel free to ask questions/send e-mail if any items require clarification.
Hints & Updates
: (updated Mon, Oct 5th)
- I strongly suggest using data type of double for this assignment.
- Make sure you modify the input values for Rate and Years as specified in class.
- Be sure to adhere to the formula listed above. Deviating from this will most likely result in erroreous results.
- I recommend using the in.nextLine() method for getting the y/n String input. You do NOT need to parse this input, since it will be a string and you are using string comparison.
- You should use the String.equals(string2) method as described in class.
- I recommend using a while loop (or do-while loop) to manage looping behavior.
- As before, NO sloppy control statements (e.g. return, break, continue, etc.) may be used. If we didn't discuss the code in class, don't use it!
- You must use the NumberFormat.getCurrencyInstance() method presented in class to format your output
