UTSA HONOR CODE: As a UTSA student, you are bound by the honor code, so DO NOT cheat on any of your coursework. By submitting this assignment, you are attesting to your own authorship based on material from the IS 2033 textbook and/or your professor. Cheating can result in any one, or combination, or all of the following: reduced or failing grade for the assignment, a signed statement of the infraction, reduced or failing grade for the course, reporting of student name to the Department Chair and faculty, Dean’s Office and COB faculty, and/or elevation to Student Conduct and Community Standards.

 

OBJECTIVE (this is not the program purpose): Code a program that uses the concepts covered in chapters 1-7 and lecture. This is not the program purpose!

 

PREP WORK: Chapters 1-7 (see Ch 7 Arrays of Objects PowerPoint slides posted with this PA); and all labs up through the present.

 

GRADING: You’ll be graded on how well you follow the program instructions and the accuracy of your output as reflected in the prompts, the output specifications, the actual Java code given to you in these instructions, and the sample output. Each line of output can be associated with multiple points in the code! The instructions, prompts and output are what the user wants. You are not at liberty to change anything, but code to these requirements.

PROGRAM INSTRUCTIONS: Code a program that stores laptop inventory objects in a one- dimensional (1D) array typed as the Laptop class. Create 3 separate class files in a project folder; declare variables at the class level; use the for loop to populate the array and extract data from the array; and code multiple methods.

 

  1. Work in groups of only two from the same section. The group will only submit one project with all the files. This means only one of the group members should submit the PA. ALL submissions will be ignored if both group members post submissions. The project folder and the main() file will reflect the last names of both group members. E.g., BunnyDuck001PA4. Through line and method comments, group members will claim authorship and the work has to be evenly distributed. Example:

 

int age = 0;         //By Bugs Bunny: STORES AN AGE

 

/**

  • By Daffy Duck

  • main() captures a first and last name, an age, and a zip

  • It multiplies the age and zip code to get a product.

  • Output will be made to the console screen and to a

  • GUI

WARNING: One group member CANNOT and MUST NOT carry the load for these assignments. All group members have to be actively engaged in developing and writing code to do well on the exams and in Java II. All group communication is to be done through your team in Blackboard.

  1. Develop your code by FIRST planning the logic. Y o u  w o n ’ t  n e e d   t o   s u b m i t y o u r p l a n .

 

  1. There is an example of a PA4 plan on Blackboard. Use that to assist with your plan.

  2. The prompts(to return press Alt then left arrow) tell you what input variables you will need.

  3. The final output specificationswill tell you the type of calculations you will need (if any) and whether you will need to declare additional variables.

  4. The sample outputwill tell you the order of logic for your code

3.Download the Creating Projects in DrJava PDF (instructor’s version) on how to create a project folderthat manages multiple .java files stored in the same folder.The project folder has the same name as the team members.java file. You are creating 3 separate .java filesto be stored in the project folder:

  1. TeamMembersLastNamesSectionNoPANo.javacontainsonly themain().

  2. LaptopInventory.java: All methods and fields are not static.Only 3 fields.All other variables, including Scanner, localized to the methods that use them.

  3. Laptop.java:All methods and fields are not static.Only 4fields.All other variables localized to the methods that use them. Methods that are prompts do not return fromthe keyboard. Input values are assigned to fields.

4.The main() will instantiate (create) an object of the LaptopInventoryclass and use that object to call processLaptops()and displayLaptops().Make sure you exit main().
