Write the code for a class called Compare. Within the class include the main() method which accepts three numbers from the user through the keyboard. The method will then compare and return the numbers to the user in descending order.
Borrowing from your previous coding challenge, accept three numbers through the keyboard from the user. Using conditional operators, print the maximum number on the screen.

/**
