Java Applet

Your team has 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 am... click for more

You have been hired by an engineering company to develop software to perform advanced geometric calculation. Need answer in VB 8

You have been hired by an engineering company to develop software to perform advanced geometric calculation. Your new boss asked you to develop an application that allows engineers to calculate the surface area and the volume of a sphere. For this, you will need to use the following formulas. Surface Area = 4 * p * r2 Volume = 4/3 * p * r3 Remember Pi is equal to 3.14. Allow the user to enter one value in the application (i.e., the radius value). Use NumericUpdown controls to allow the user to enter the values. Display the result in a text box and set it as read-only. Make the Calculate button the Accept button. Create a Clear button to clear the result text box and reset ... click for more

Phased Development Approach

What are the advantages and disadvantage of a phased development approach?

Java Method

Write a method, removeAll, that takes three parameters: an array of integers, the length of the array, and an integer, say, removeItem. The method should find and delete all occurrences of removeItem in the array. If the value does not exist or the array is empty, output an appropriate message. (Note that after deleting the element, the array size will be reduced.) You may assume that the array is unsorted.

Java Calculator

The Programming Example: Calculator in Chapter 12 is designed to do operations on integers. Write a similar program that can be used to do operations on decimal numbers. (Note: If division by zero occurs with values of the int data type, the program throws a division by zero exception. However, if you divide a decimal number by zero, Java does not throw the division by zero exception; it returns the answer as infinity. However, if division by zero occurs, your calculator program must output the message ERROR: / by zero.)
