Hi,This assignment was divided into 2 parts the first part has been completed and the second part needs to be done there are 4 simple tasks for the second part I have attached both the pdf files for the first and second part and I will attach my own work off the first part when I have accepted your bid. Kind Regards _syd_s3_assignment_part2_handout.pdf _syd_s3_a1_handout.pdf Unformatted Attachment Preview CSE1/CSE4IOO Semester 3, 2019 Assignment – Part 2 Assessment: This Part 2 of the assignment is worth 15 \% of the final mark for this subject. Due Date: To be3, announced Feb 2020 Delays caused by computer downtime cannot be accepted as a valid reason for a late submission without penalty. Students must plan their work to allow for both scheduled and unscheduled downtime. Penalties are applied to late assignments (accepted up to 5 days after the due date only). See the university policy for details. Individual Assignment: This is an individual assignment. You are not permitted to work as a group when writing this assignment. Copying, Plagiarism: Plagiarism is the submission of somebody else’s work in a manner that gives the impression that the work is your own. The Department of Computer Science and Information Technology treats academic misconduct seriously. When it is detected, penalties are strictly imposed. Refer to the unit guide for further information and strategies you can use to avoid a charge of academic misconduct. All submissions will be electronically checked for plagiarism. Objectives: The general aims of this assignment are: • To analyze a problem in an object-oriented manner, and then design and implement an object-oriented solution that conforms to given specifications • To practise using inheritance in Java • To practise file input and output in Java • To make implementations more robust through mechanisms such as exception handling. Submission Details: Please follow your lecturer’s instructions. Compiling and Execution Requirements: We should be able to compile your classes with the simple command javac *.java, and execute your programs with a simple command, e.g. java RRShelterMenu. 1 Two-Part Assignment • This is part 2 of the tw0-part assignment • When you complete part 2, you would have implemented a menu-driven program whose requirements are described below (which is a slight variation of what was described in part 1) • Everything described for part 1 is applied for part 2, except where they are otherwise explicitly stated. For Part 2 of the assignment, complete the following tasks. Task 1 – ArrayList • Modify what you did in part 1 so that you will maintain the collection of animals kept in the shelter as an ArrayList, instead of an array. • Test your modifications with the test programs RRShelterPart2Tester1 Add and RRShelterPart2Tester2 Release, in Appendices 1 and 2. Your classes must be such that the test programs (for this and other tasks) can be run without change. Task 2 – Food List • Add code to your classes so that you can display the food list for the animal in the shelter. • Test your classes with the test program RRShelterPart2Tester3 Foods in Appendix 3. As stated above, your classes must be such that the test program can be run without change. Note: In the handout of part 1, the line showing food for a kangaroo does not start with the animal tag. This is a mistake. It should be corrected to include the animal tag as shown in the example below: M001 Kangaroo: no extra feed F002 Kangaroo: extra cut grass paddock 1 M003 Joey: milk supplement F004 Joey: no extra feed M005 apple banana M006 apple banana grapes 2 Task 3 – Saving and Reading Data • Implement necessary methods so that you can write the animal data to a text file and read the data from the text file. The file name and the file format are exactly as described in part 1 handout. • Test your classes with the test programs RRShelterPart2Tester4 WriteToFile and RRShelterPart2Tester5 ReadFromFile in Appendices 4 and 5. Again, your classes must be such that these test programs can be run without change. Task 4 – Providing a Menu Implement the class that presents the menu should have the following options: ****************** Recovery & Release ****************** 1: Add a Kangaroo 2: Add a Joey 3: Add a Possum A: Display the Animals F: Display the Food List R: Release an Animal Q: Quit Please select an option: i. Before displaying the menu, RRShelter.txt. the program read the data from the text file If the file does not exist or contains errors, an error message should be displayed and the program terminates. ii. Then the menu is repeatedly be displayed after each (case-insensitive) user selection is executed, until the user chooses ’Q’ or ’q’ to quit the program. If a chosen option is invalid, the program displays an error message and returns to the main menu. If an exception is thrown in carrying out an option, the program displays an error message and returns to the main menu. That is, the program must be robust. Note that the whole program (which includes any classes used) must ensure that the data maintained by the application are valid – as described in part 1 handout. iii. Of course, for options 1, 2, 3 and R, the program must get the required data entered by the user from the keyboard. For example, for option R, the user needs to enter the type of animal to be released. iv. After quiting the menu and before terminating, the collection should be written back to the text file RRShelter.txt (in the overwriting mode). 3 Marking Scheme Overview • 94 marks will be given to Tasks 1-4. • 6 marks will be given to program design, coding style and readability. Return of Assignments Department policy requires that assignments are returned within 3 weeks of the submission date. Students will be notified by email and via the CSE1 LMS forum when marking sheets are available for collection. 4 Appendix 1 public class RRShelterPart2Tester1_Add { public static void main(String [] args) throws Exception { // Test add animals - valid cases System.out.println(Test 1:); test1(); // Inva;id cases System.out.println(\nTest 2); test2(); System.out.println(\nTest 3); test3(); System.out.println(\nTest 4); try{ test4();} catch(Exception e){ System.out.println(e.getMessage());} System.out.println(\nTest 5); try{ test5();} catch(Exception e){ System.out.println(e.getMessage());} } // Add animals - valid cases public static void test1() throws Exception { RRShelter shelter = new RRShelter(); shelter.addKangaroo(M001, ’S’, 1); shelter.addJoey(M002, ’S’, 1, 4.5); shelter.addPossum(M003, ’S’, apple|banana, U1); System.out.println(shelter); } public static void test2() throws Exception // Add kangaroo - tag number is not new { RRShelter shelter = new RRShelter(); shelter.addKangaroo(M001, ’M’, 2); System.out.println(shelter); try { shelter.addKangaroo(M001, ’M’, 2); } catch(Exception e) { System.out.println(e); } finally { System.out.println(shelter); } } 5 public static void test3() throws Exception // Add kangaroo - invalid tag { RRShelter shelter = new RRShelter(); System.out.println(shelter); try { shelter.addKangaroo(A001, ’S’, 1); } catch(Exception e) { System.out.println(e); } finally { System.out.println(shelter); } } public static void test4() throws Exception // Add joey - invalid weight { RRShelter shelter = new RRShelter(); System.out.println(shelter); try { shelter.addJoey(M001, ’S’, 1, 2.5); } catch(Exception e) { System.out.println(e); } finally { System.out.println(shelter); } } public static void test5() throws Exception // Add possum - invalid territory { RRShelter shelter = new RRShelter(); System.out.println(shelter); try { shelter.addPossum(M001, ’S’, apple|banana, X1); } catch(Exception e) { System.out.println(e); } finally { System.out.println(shelter); } } 6 } /* Sample output: Test 1: RR Shelter: Kangaroo[tag: M001, stayTime: S, paddock: 1] Joey[tag: M002, stayTime: S, paddock: 1, weight: 4.5] Possum[tag: M003, stayTime: S, diet: apple|banana, territory: U1] Test 2 RR Shelter: Kangaroo[tag: M001, stayTime: M, paddock: 2] java.lang.Exception: Error: Tag number already exists!

Requirements Description Several organisations across Australia are dedicated to caring for injured wildlife. The general aims of such organisations are to return healthy animals to their natural environment. One such organisation is the Recovery and Release Shelter (R&R Shelter). They monitor animals that are close to being ready for release and determine when animals in their care will be released. The shelter has employed you to implement a small interactive application to manage their operations. The application stores all information about each animal in a text file that must be loaded when your program starts. The shelter looks after Kangaroos, Joeys and Possums. The shelter has paddocks for the Kangaroos and Joeys and the Possums are kept in cages. Information on Kangaroos is stored in 4 lines. A typical entry (record) is: Kangaroo M3425 M 1 • Line 1 is the type of animal (Kangaroo, Joey or Possum) - not mutable ... Purchase answer to see full attachment
