| | Chapter 18. Player Cancellation | |
PlayerCancellation uses the cancellation
betting system. This player allocates their available budget into a
sequence of bets that have an accelerating potential gain as well as
recouping any losses.
List sequence = new List();This List keeps the bet
amounts; wins are removed from this list and losses are appended
to this list. THe current bet is the first value plus the last
value.
Outcome outcome ;This is the player's preferred outcome.
PlayerCancellation();This uses the resetSequence
method to initalize the sequence of numbers used to establish
the bet amount. This also picks a suitable even money
Outcome, for example, black.
resetSequence();Puts the initial sequence of six
Integer instances into the
sequence variable. These
Integers are built from the values 1
through 6.
void placeBets();Creates a bet from the sum of the first and last values of
sequence. The first value is at index 0. The
last value's position depends on the size of the
List.
void win(Bet bet);Uses the superclass method to update the stake with an
amount won. It then removes the fist and last element from
sequence.
void lose(Bet bet);Uses the superclass method to update the stake with an
amount lost. It then appends the sum of the first and list
elements of sequence to the end of
sequence as a new
Integer value.
