java - Return keywords for a boolean statement -


I am writing an incredibly primitive blackjack game for high school programming class and playing with a boolean writing Public Boolean Dealer Tracker (if (a == 11 || one == 12 || one == 13) {a = 10;} Dealerhand value = A + Dealerhand value; If (DealerHold Value 21) {DealerHand.Set Text ("The House Was Busted !! !! Everyone Wins !!"); Back to True;} And If (DealerHand Value <21) {Return Null;} and if (dealer value value == 21) {return false;}}

I am getting an error saying that return tap (I Fancy blockcoat was not able to manage to work) is invalid. However, to work for this bullion, I really need three return statements, so my question is: is there any way to do zero work? , Or can I put it in its place, which is still appropriate I'm stupid here, or I'm stupid here.

Please note that I do not really need this boolean, so if you think there is no solution, just recommend boolean removal . "post-text" itemprop = "text">

boolean can not be null . You can basically have two options: see

return your function to a boolean (note capital 'B'). Boolean is more than a primitive object, and it may also be null .

A better solution would be to define an enum, this will help you to protect the meaning of return value, which will make your code more readable and easy to maintain.
