The question is related to problem 6.33 from Java how to program 9th edition. with a twist.

(Craps Game Modification) Modify the craps program of Fig. 6.8 to allow wagering. Initialize variable bankBalance to 1000 dollars. Prompt the player to enter a wager. Check that wager is less than or equal to bankBalance, and if its not, have the user reenter wager until a valid wager is entered. Then, run one game of craps. If the player wins, increase bankBalance by wager and display the new bankBalance. If the player loses, decrease bankBalance by wager, display the new bank- Balance, check whether bankBalance has become zero and, if so, display the message "Sorry. You busted!" As the game progresses, display various messages to create some chatter, such as "Oh, you're going for broke, huh?" or "Aw c'mon, take a chance!" or "You're up big. Now's the time to cash in your chips!". Implement the chatter as a separate method that randomly chooses the string to display.

The addition is the following:

Add a method called wager() so that you could ask for the wager and the program will return the wager amount.

create an overloaded method balance(), that takes either one or two parameters: (balance) (balance, wager). Balance() returns a type Boolean (True/False), if Balance is > 0 then returns True else False. If Balance - wager > 0 then return True else False.

I have the following code and am not getting it yet. Please help. Thank you.
