RetailItem Exception

Program Plan:

RetailItem.java:

  • Declare the class “RetailItem”.
  • Declare the private variable “desp” as “string”.
  • Declare the private variable “units” as “int”.
  • Declare the private variable “price” as “double”.
  • Initialize the constructor “RetailItem”.
    • Assign “desp” as empty string.
    • Assign “units” as “0”.
    • Assign “price” as”0.0”.
  • Initialize the parameterized constructor “RetailItem”.
    • Assign “desp” as “d”.
    • Assign “units” as “u”.
    • Assign “price” as “p”.
  • Mutator function “setDesp()”
    • Assign “desp” to “d”.
  • Mutator function “setUnits()”.
    • Check whether the “u” is greater than “0”
      • Throw the exception.
    • Otherwise, assign “u” to “units”.
  • Mutator function “setPrice()”.
    • Check whether the “p” is greater than “0”
      • Throw the exception.
    • Otherwise, assign “p” to “price”.
  • Define the accessor function “getDesp()”, “getUnits()” and “getPrice()”.

NegativeUnitsException.java:

  • Definition for “RetailDemo” class.
  • Definition for main class.
    • Declare the required variables.
    • Create an object for scanner class.
    • Create a retail item object.
    • Get the description from the user.
    • Set the item description.
    • Get the items units.
      • Inside the try block,

        • Assign “true” to “input.”
      • Inside the catch block,
        • Print the error
        • Assign “false” to “input”.

Object-Oriented Programming In this separate files. ent, you'll need to build and run a small Zoo in Lennoxville. All classes must be created in Animal (5) First, start by building a class that describes an Animal at a Zoo. It should have one private instance variable for the name of the animal, and one for its hunger status (fed or hungry). Add methods for setting and getting the hunger satus variable, along with a getter for the name. Consider how these should be named for code clarity. For instance, using a method called hungry () to make the animal hungry could be used as a setter for the hunger field. The same logic could be applied to when it's being fed: public void feed () { this.fed = true; Furthermore, the getter for the fed variable could be named is Fed as it is more descriptive about what it answers when compared to get Fed. Keep this technique in mind for future class designs. Zoo (10) Now we have the animals designed and ready for building a little Zoo! Build a class…
