Method Detail

main

public static void main(java.lang.String[] args)

NOTE:
Some clarification,

currentPlayers[5][]
Is for storing current ride players, 1 adult & one child is consider 2 players, and 1 adult is considered as 1 player.

transactions[1000][]
Is for storing transactions. 1 adult or 1 adult & 1 child is considered one transaction.

BigDecimal
The reason for using BigDecimal instead of double or float is because double/float can inexact as
you performed multiple calculation (addition, subtraction, multiplication, division),
which makes floats and doubles inadequate for dealing with money.
