Specifications: Lions, Tigers, and Bears Pet Clinic needs an application that displays basic services. The application should be designed with checkboxes to select the various services (such as office call, vaccination, grooming, etc). As each service is selected, the charge for the service should display in an associated label. (When the checkmark is removed, the amount should be removed). As each selection is made, the charges should be added into the total (a variable… consider scope), and displayed in a Total Due area on the application (currency format). Align all numeric data appropriately. Consider what should happen when the checkmark is removed. Include at least 8 services that your pet clinic performs. Include a Clear and Exit button. The clear should clear all checkboxes, appropriate labels, and the total variable. Use the standard Microsoft naming conventions for all controls. Include appropriate comments in your code.

Scenario You work for a small company that creates text-based games. You have been asked to pitch an idea to your team for a text-based adventure game with a theme and environment of your choice. Your game must include different rooms, items, and a villain. The basic gameplay will require the player to move between different rooms to gather all of the items. A player wins the game by collecting all the items before encountering the villain. The player will have two options for commands in the game: moving to a different room, and getting an item from the room they are in. Movement between rooms happens in four simple directions: North, South, East, and West. Directions In this project, you will break the problem down into a set of requirements for your game program. Then you will design your game by creating a storyboard and pseudocode or flowcharts. Remember, in Project One, you are only designing the game. You will actually develop the code for your game in Project Two. Review the…

Java Programming: Finish the JInsurance application that allows the user to choose insurance options in JCheckBoxes. Use a ButtonGroup to allow the user to select only one of two insurance types—HMO (health maintenance organization) or PPO (preferred provider organization). Use regular (single) JCheckBoxes for dental insurance and vision insurance options; the user can select one option, both options, or neither option. As the user selects each option, display its name and price in a text field; the HMO costs $200per month, the PPO costs $600 per month, the dental coverage adds $75 per month, and the vision care adds $20 per month. When a user deselects an item, make the text field blank.
