Question

JAVA program. I have created a game called GuessFive that generates a 5-digit random number, with individual digits from 0 to 9 inclusive. (i.e. 12345, 09382, 33044, etc.) The player then tries to guess the number. With each guess the program displays two numbers, the first is the number of correct digits that are in the proper position and the second number is the sum of the correct digits. When the user enters the correct five-digit number the program returns a statement that tells them that the user found the correct number, and how many tries it took the user to find the number.
The game was originally written as a standalone program.
• Alter the class to allow it to be instantiated as a GuessFive class object.
• Create a new Score class that has instance variables for a String name and an int score.
• Alter the class to include a best-score list, as an array of Score objects,(Score[]) that holds the top five scores in ascending order. (low score is the best score) This list must be available to all instances of the class. Display the best-score list, name and score, at the end of each successful game along with the user’s score. If there is space on the scoreboard, new scores are added to the scoreboard. If the scoreboard is full a new score is added to the score board if it beats one of the scores on the scoreboard, and the worst score is pushed off the scoreboard.
• Create a driver program to test your conversion, that instantiates and runs at least 6 instances of the GuessFive class.
Note: Play the game a couple of times to get a feel for how it works before you try to modify it.
