Create the following class to represent the sprite objects in the game.
Sprite |
|
+ Sprite (String); + Sprite (String, int, int); + setName (String): void + setX(int): void + setY(int): void + getName (): String + getX (): int + getY (): int + collide (Sprite): boolean + toString (): String |
Create ten (10) game objects as Sprite type and stored in an array. All the games objects location (x & y) must be set in range 1 to 800 randomly.
The collide method is a method to test the collision between the current sprite with another sprite (from parameter). This method will check the distance in between two sprites based on the current x and y location using Pythagoras theorem. If the distance of 2 objects is less than 10, then the method will return true. Otherwise false will be returned.
Create a driver class called TestSprite which will:

Draw a Use Case Diagram based on the following narrative:
A company called Joyful Foods is introducing a system that allows customers to make food orders through their mobile phones. Customers can register new accounts, which include validating credit card information. They can view the menus of various restaurants and they will have the option of checking the restaurants' ratings while doing so. Customers also can rate any restaurant with a rating from 1-10. When they make food orders, they will have the option of paying online. Company staff will have to confirm food orders with the customers by calling them to make sure that the orders are valid. Furthermore, the company hired drivers will be able to view order information to see the location of the customers. Lastly, managers will be able to grant monthly rewards for drivers after checking their performance.

If I want to show an exception in JAVA GUI that checks if the date format is correct or the date doesn't exist, and if no input is put in how do I do that. For example if the date format should be 01-11-2020, and user inputs 11/01/2020 inside the jTextField it will show an error exception message that format is wrong, and if the user inputs an invalid date, it will print that the date is invlaid, and if the user puts no value inside the text box, it willl print an exception message that there needs to be a value.
