Task

Task 1 ( 60 marks)

University grading system maintains number of tables to store, retrieve and manipulate student marks. These tables reside in a centrally or locally located server known as ‘database server’. ‘Student_marks_ITC000’ is one of the tables which contains following information for all the students enrolled for ITC000: ‘Student ID’, ‘Student Name’, ‘Marks obtained in Assignment 1’, ‘Marks obtained in Assignment 2’, ‘Marks obtained in Assignment 3’ and ‘Marks obtained in Final’. A sample of the table may look like as follows:

Student ID	Name	Assignment1	Assignment2	Assignment3	Final
1001	Janet	80	100	90	85
1002	Daniel	60	70	75	90

Write a JAVA program that would perform following tasks:

Create Table: Create a table that is capable to store above information.
Insert Record: If the user of your program wants to insert a record, your program should ask for all the fields of the record and insert them in the table.
Search: The user of your program should be able to search a particular record by ID or any other field.
Calculate final score: Take a student’s ID as input and displays his/her score in each item. It also should calculate and display the final score where final score = 10%(Assignment 1) + 20%(Assignment 2) + 20%(Assignment 3) + 50%(Final exam).

Task 2 (40 marks)

Write a JAVA program that would simulate a number of cars’ (e.g. 4) speed meter using the concept of Multithreading. A car’s speed can be both increased and decreased using specified keys from the keyboard. The speed of all the cars should be displayed on the screen both in text format and graphically simultaneously.

Note: For further clarification and concerns about the assignment, students are recommended to talk to the subject lecturer at PDalmaris@studygroup.com.

Rationale

This assignment is designed to asses following learning outcomes:

be able to create, connect to and update a relational database using the Java Database Connectivity (JDBC);
be able to design and implement multithreaded Java applications;
be able to demonstrate the use of the inheritance features of the Java language to design and implement complex object-oriented programs;

Marking criteria

The marking criteria are represented via the following marking guide.

Task 1

Items	Full Marks	PS	CR (PS+)	DI (CR+)		HD (DI+)
Presentation	10	Very basic presentation (no source code or screen shots were included)	Only report (with screen shots) is present but no source code was submitted	Report, screen shots and source code both are submitted as required		The presentation includes all requirements and is easy to read and understand
Program execution	10	Program is not running but the source code indicates the correctness	Program is running but not working properly	Program is running perfectly but cannot handle unexpected inputs/events		Program is running perfectly and not crashing because of unexpected inputs/events
Create table	10	A table is created but provides no error/warning message	Any error/warning is handled	Program checks the validation of the fields before sending the query to the MySQL	Some suggestions about fields and table creation confirmation message is displayed
Insert record	10	A record is inserted but provides no error/warning message	Any error/warning is handled	Program checks the validation of the fields before inserting a record in the table	Some suggestions about fields and insertion confirmation message is displayed
Search	10	A record is searched correctly but provides no error/warning message	Any error/warning is handled	Program checks the validation of the field to be searched before running search operation in the table	Some suggestions about fields and all search results are displayed
Calculate final score	10	There are some mistakes in calculating final score	Final score is perfectly calculated	All error/warning message is properly handled

Task 2

Items	Full Marks	PS	CR (PS+)	DI (CR+)	HD (DI+)
Presentation	8	Very basic presentation (no source code or screen shots were included)	Only report (with screen shots) is present but no source code was submitted	Report, screen shots and source code both are submitted as required	The presentation includes all requirements and is easy to read and understand
Program execution	8	Program is not running but the source code indicates the correctness	Program is running but not working properly	Program is running perfectly but cannot handle unexpected inputs/events	Program is running perfectly and not crashing because of unexpected inputs/events
Speed showing in text	12	There are some errors in showing the actual speed of all the cars	No error in showing the speed itself, however the interface is not fully clear to the user	The speed of corresponding cars, increase/decrease are perfectly working and displayed clearly to the user
Speed showing using graphics	12	There are some errors in showing the actual speed of all the cars	No error in showing the speed itself, however the interface is not fully clear to the user	The speed of corresponding cars, increase/decrease are perfectly working and displayed clearly to the user

Note: Marks will be scaled to adjust this assessment item's actual mark.

Presentation

Following items are to be submitted in the Turnitin (For each task):

Report: The report (in .doc or .pdf format) should explain how to run your program (1 or 2 page long) and any settings needed to run your program. Enough number of screenshots should be shown in the document. In case if the assignment marker fails to run your program, because of any inconvenience, these screenshots would show how the program worked on your machine/environment.
Source code and other files: All source codes, exe file and other relevant files must have to be zipped in a folder such that unzipping would keep the file/folder structure unaffected.
