Question
Class: The name of the class is Money. This means that the code must be stored in the file Money.java Instance data: There are two integer values for the instance data representing the dollars and cents. These must be declared as private. Instance methods: There are six methods in the class. All methods are public. 1. setMoney(int dollarsln, int centsln) ?Set the dollars and cents to the values of the parameters. If either input is negative, set the dollars and cents to O. 2. add(Money moneyln) ? add the dollars and cents of the parameter to the current object. If the cents exceeds 100, adjust the dollars and cents accordingly. 3. subtract(Money moneyln) ? subtract the parameter from the current object If the cents fall below O, then the dollars and cents must be adjusted. If the number of dollars falls below O, then set both the dollars and cents to O 4. boolean equals(Money moneyln): return true if both the dollars and cents of the parameter match the dollars and cents of the current object, otherwise return false 5. boolean IessThan(Money moneyln): return true if the current object represents less money than the parameter. otherwise return false 6. String toString: return the values of the object as a String formatted as $dd.ccExplanation / Answer
