Introduction

This assignment asks you to implement a PriceTag class as well as a PriceTagTester class. The PriceTag should model a simple price tag. The PriceTagTester class should be a complete test driver -- it should excercise all of its functionality.

The PriceTagclass

Please implement a class specification for a class that models aspects of a price tag, as follows:

• It should contain the name of an item, for example, a "Bostich Stapler"
• It should contain the items price in dollars and fractions thereof, for example, 4.52
• It should contain the items stockNumber, for example, "045-223-AXJ"
• All three of these properties should be set at initialization.
• All three of these properties should be individually accessible through methods.
• The price should be changeable, any time.
• The class should have a method, defined as follows:
  • int compareTo (Object o)
  • This method should return 0, if and only if the two items have the same price. It should return a negative number if and only if the comparing item is less than the item passed as a parameter. It should return a positive number otherise (the comparing item is greater than the item passed as a parameter).

Notes

• Items listed in italics are strong suggestions for identifier names
• Getter (Accessor) methods can simply be name, getProperty(), where "get" is literal, and "Property" is the name of the attribute.
• Setter (Mutator) methods can simply be name, setProperty(), where "set" is literal, and "Property" is the name of the attribute.
• It might make sense, or be required, to have multiple forms of the constructor, e.g. more than one constructor, each with a different parameterization
