Consider a class coin that representsa coin. the class has
methods such as getvalue, toss, andisheads. the method getvalue
returns the value, or denomination, of acoin. the method toss
simulates a cointoss in which the coin lands either heads up or
tails up. themethod isheads returns true if a coin isheads up.
suppose that coinlist is anadt list of coins that have
randomlyselected denominations. toss each of these coins. if the
result ofa coin toss is heads move the coin to a second listcalled
headslist; if it is tails, leavethe coin in the original list. when
you are finished tossing coins, compute the total value of the coins
that came up heads. assume that the list headslist hasbeen created
for you and is emptyinitially.
