Joe’s Automotive
Joe’s Automotive performs the following routine maintenance services:
- Oil change—$26.00
- Lube job—$18.00
- Radiator flush—$30.00
- Transmission flush—$80.00
- Inspection—$15.00
- Muffler replacement—$100.00
- Tire rotation—$20.00
Joe also performs other nonroutine services and charges for parts and labor ($20 per hour). Create an application that displays the total for a customer’s visit to Joe’s. The form should resemble the one shown in Figure 6-31.
The application should have the following value-returning methods:
- OilLubeCharges—Returns the total charges for an oil change and/or a lube job, if any.
- FlushCharges—Returns the total charges for a radiator flush and/or a transmission flush, if any.
- MiscCharges—Returns the total charges for an inspection, muffler replacement, and/or a tire rotation, if any.
- OtherCharges—Returns the total charges for other services (parts and labor), if any.
- TaxCharges—Returns the amount of sales tax, if any. Sales tax is 6% and is charged only on parts. If the customer purchases services only, no sales tax is charged.
- TotalCharges—Returns the total charges.
The application should have the following void methods, called when the user clicks the Clear button:
- ClearOilLube—Clears the check boxes for oil change and lube job.
- ClearFlushes—Clears the check boxes for radiator flush and transmission flush.
- ClearMisc—Clears the check boxes for inspection, muffler replacement, and tire rotation.
- ClearOther—Clears the text boxes for parts and labor.
- ClearFees—Clears the labels that display the labels in the section marked Summary.

- Change the following code so that it checks the following 3 conditions: 1. there is no space between each cells (imgs) 2. even if it is resized, the components wouldn't disappear 3. The GameGUI JPanel takes all the JFrame space, so that there shouldn't be extra space appearing in the frame other than the game. Main(): Labyrinth labyrinth = new Labyrinth(10); Player player = new Player(9, 0); Dragon dragon = new Dragon(9, 9); JFrame frame = new JFrame("Labyrinth Game"); GameGUI gui = new GameGUI(labyrinth, player, dragon); frame.add(gui); frame.setSize(600, 600); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true); public class GameGUI extends JPanel { private final Labyrinth labyrinth; private final Player player; private final Dragon dragon; //labyrinth, player, dragon are just public classes private final ImageIcon playerIcon = new ImageIcon("data/images/player.png");…arrow_forwardMake the following game user friendly with GUI, with some simple graphics.

He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. The player can move only in four directions: left, right, up or down. There are several escape paths in all labyrinths. The player’s character should be able to moved with the well known WASD keyboard buttons. If the dragon gets to a neighboring field of the player, then the player dies. Because it is dark in the labyrinth, the player can see only the neighboring fields at a distance of 3 units.

Palindrome numbers are numbers that their decimal representation can be read from left to right and from right to left (e.g. 12321, 5995, 1234321). The program will create T worker threads to check for prime and palindrome numbers in the given range (T will be passed to the program with the Linux command line). Each of the threads works on a part of the numbers within the range. Your program should have some global shared variables: • numOfPrimes: which will track the total number of prime numbers found by all threads. numOfPalindroms: which will track the total number of palindrome numbers found by all threads. numOfPalindromic Primes: which will count the numbers that are BOTH prime and palindrome found by all threads. TotalNums: which will count all the processed numbers in the range. In addition, you need to have arrays…arrow_forwardHow do you distinguish between hardware and a software problem?
