Problem

11.1 Enums — capstone: coins with data

Write a complete program with an enum Coin whose constants carry their value in cents: PENNY(1), NICKEL(5), DIME(10), QUARTER(25). Give it a field, a constructor and a getter.

Read a count and then that many coin names. Print the total value, then how many kinds of coin the enum has.

For 3 then QUARTER DIME PENNY:

36
4

Coin.valueOf(name) turns the text into a constant, and Coin.values().length counts them.
