Testing Random Numbers Project SDEV 1060 Project. A senior developer is working on a project and has asked you to do some testing for him. One of the methods in his project creates a random number between supplied minimum and maximum values. He has written the method that will create that random number, run it a few times, and thinks it looks go…

Create a project that calculates miles per gallon for a given trip, and accumulates the miles and gallons to calculate an overall MPG for the vehicle. Create a class named MPG that includes private instance variables for miles, gallons, and mpg, which are doubles. Add class variables for totalMiles, totalGallons, and totalMPG, which are doubles,…

SDEV 2210 Project. This project simulates the inventory for a fleet of cars. The fleet is an array of Car objects. A Car has a name and an ArrayList of Miles Per Gallon (MPG) objects. An MPG object has variables for miles, gallons, and miles per gallon, which is calculated in the constructor. The driver class will instantiate 3 Car objects and s…

Modified the Tip Calculator app that’s presented in chapter 6, so it uses the OnKeyListener interface to handle Key events instead of using the OnEditorActionListener interface to handle Key events. Taken from Murach's Android Programming, 2nd Edition by Joel Murach. Page 195, Exercise 6-2

Using app from 2-2, this updates the fields to calculate tip and total based on user entry. It also takes into consideration rotation of smartphone and changes the launch icon. Taken from Murach's Android Programming, 2nd Edition by Joel Murach. Page 91, Exercise 3-1.

Add the seven TextView widgets and one EditText widget to the layout. Set the id and text properties of each widget. The app should allow you to enter a subtotal, but that shouldn’t cause the discount percent, discount amount, or total values to change. Taken from Murach's Android Programming, 2nd Edition by Joel Murach. Page 53, Exercise 2-2.

Create a program named TestFileAndDirectory that allows a user to continually enter directory names until the user types end. If the directory name exists, display a list of the files in it; otherwise, display a message indicating the directory does not exist. If the directory exists and files are listed, prompt the user to enter one of the file…

Create a program for The Cactus Cantina named FoodOrder that accepts a user’s choice from the options in the accompanying table. Allow the user to enter either an integer item number or a string description. Pass the user’s entry to one of two overloaded GetDetails() methods, and then display a returned string with all the order details. The met…

Create a project named FiveColors2. Its Form contains at least five RadioButton objects, each labeled with a color. When the user clicks a RadioButton, change the BackColor of the Form appropriately. Taken from Microsoft Visual C# 2015: An Introduction to Object-Oriented Programming 6th Edition by Joyce Farrell. Page 603, Exercise 3.

Create a project named RecentlyVisitedSites that contains a Form with a list of three LinkLabels that link to any three Web sites you choose. When a user clicks a LinkLabel, link to that site. When a user’s mouse hovers over a LinkLabel, display a brief message that explains the site’s purpose. After a user clicks a link, move the most recently …

Write a program named SubscriptExceptionTest in which you declare an array of 20 doubles and store values in the array. Write a try block in which you place a loop that prompts the user for a subscript value and displays the value stored in the corresponding array position. Create a catch block that catches any IndexOutOfRangeException and displ…
