Create a USMoney class with two integer instance variables dollars and cents. Add a constructor with two parameters for initializing a USMoney object. The constructor should check that the cents value is between 0 and 99 and, if not, transfer some of the cents to the dollars variable to make it between 0 and 99. Add a plus method to the class that takes a USMoney object as its parameter. It creates and returns a new USMoney object repre- senting the sum of the object whose plus( ) method is being invoked and the parameter. It does not modify the values of the two existing objects. It should also ensure that the value of the cents instance variable of the new object is between 0 and 99. For example, if x is a USMoney object with 5 dollars and 80 cents, and if y is a USMoney object with 1 dollar and 90 cents, then x.plus(y) will return a new USMoney object with 7 dollars and 70 cents. Also, create a USMoneyDemo class that tests the USMoney class.
