Java program

Write a class encapsulating the concept of coins, assuming that coins have the following attributes: a number of quarters, a number of dimes, a numbers of nickels, and a number of pennies. Include a constructor, the accessors and mutators, and method toString. Also code the following methods: one returning the total amount of money in dollar notation with two significant digits after the decimal point, and others returning the money in quarters (for instance, 0.75 if there are three quarters), in dimes, in nickels, and in pennies. Write a client class to test all your methods (including your accessors and mutators).
