Question

I'm in java one and need help with this code. please follow the directions given and test your program to make sure it works as it is required. I will apreciate your help. thank you.please use the given code.

Programming Concepts

1. Random Numbers

2. Methods
3. Passing Arrays

Assignment Description

-- Write a program that will emulate a slot machine. The machine will continue to run until the user wishes to stop or runs out of money. The machine generates 3 random characters.

-- Every time the user wants to play again, subtract $1 from their total

--You will copy a template of the program from this directory into yours by issuing the following command:

cp ~lkoperski/1404_Lab/Assignments/SlotMachine.java .

here is the template. please use it as given and fill the missing information to make the program work.

Required Methods

• public static void genRandSlots ( char[] slots )
o I have created a char array for you, called symbols, with an initializer list of the heart, spade,club, and diamond symbols

o For each element of the slots array, you need to randomly pick one of the symbols and store it into the slots array

public static int getWinnings( char[] slots )
o Based on the number of matching characters in the slots array, calculate the amount of money that the user wins, and return it.

o If three characters match >? The user wins $10

o If only two characters match > ? The user wins $5

o If none of the characters match > ? The user wins $0

Methods Already Written For You

public static boolean playAgain () o Asks the user if they want to play again

o Returns true if they say do
o Returns false if they say don't

public static void printSlots () o Prints out the slots

Output Example 1 – Getting two matching symbols

user@loki:~$ java SlotMachine

You have $3

???????

You won $0
Would you like to pay $1 to play again? ( Y / N ): y

====================================================

You have $2

???????

You won $5
Would you like to pay $1 to play again? ( Y / N ): y

====================================================

You have $6

???????

You won $0
Would you like to pay $1 to play again? ( Y / N ): n
