CSC 8205 Advanced Java

Transcription

1 Please read this first: 1) All the assignments must be submitted via blackboard account. 2) All the assignments for this course are posted below. The due dates for each assignment are announced on blackboard. Keep in mind that depending on the situation, the content of each of the assignments may change up to a week before the due date. 3) All the files created for the same assignment must be saved in the same directory and compressed together into a single zip file and submitted. 4) You compress and submit only the files required. That includes all the source and class files. If you use an IDE like NetBeans, simply compress the entire project directory. 5) Programs must run properly for getting any credit. Check it yourself before compressing the files. 6) Compression must be done only in the zip format (using windows XP or WinZip). 7) All submitted source files must have a header comment that includes your name, course name and assignment number. You WILL lose a point if you miss this instruction. Assignment 1: 1) GUI programming and event handling by implementing various Listener classes in Java. 2) Exception handling in Java. 3) Various awt and swing components such as menus, buttons, tabbed environment, combo boxes etc. 1) Java topics notes. 2) Java API on various classes. 3) GUI programming code examples. 4) NetBeans IDE provides an easy drag and drop interface for creating GUI applications. 1) Download the tilepuzzle.jar file from the blackboard. 2) Double click on the jar file to run the PuzzleMenu program. Your assignment is to create a program that incorporates all the features of that example. 3) Your menu should not resemble what I have created. Use your own GUI with menus, tabs etc. Use TabbedPane class for creating tabs. 4) Unzip the jar file using the command jar xvf tilepuzzle.jar. Please note that the jar.exe file is in the bin directory of your jdk installation. You must append the Path variable to include that. For instance, Path = %Path%; C:\Program Files\Java\jdk1.7.0_02\bin 5) You will be replacing PuzzleMenu.class with your own version, but you will be reusing the two classes TilePuzzle.class and ExampleFileFilter.class by importing into your PuzzleMenu.java.

2 6) Also read the pdf file for hints. You will also be using the mf file to create the jar file again. Both NetBeans and Eclipse can also create executable jar files from your project at the click of a button. 7) Please incorporate all the following features in your PuzzleMenu code. a. Title bar must show your name. b. You must have menus for creating tile puzzle after configuring various parameters. c. Other menu items such as Help and About will add to your credit. d. There must also be option for saving the puzzle with the current position of the tiles also saved after a few moves. You need to use object streams to implement this. e. Many puzzles may be open and the save menu must save the puzzle with the focus. Use WindowFocusListener to implement this. f. Must be able to choose from saved puzzles to reload. Use File Filter to implement display of only specific file types in the load dialog box. g. Closing the main window should close all the puzzles and the program. 8) You only have to create the code for the menus (PuzzleMenu.java). You must use tabbed interfaces for specifying some configuration values for the puzzles. 9) Look under jdk documentation on file chooser for using ExampleFileFilter class. 10) Public methods of TilePuzzle class are documented in pdf file. You simply call them from your menus. 11) Also code snippets for file management are provided in the pdf file. 12) Use your imagination to rearrange the menus. They should not resemble the example I gave nor should they resemble your friend s. 13) Create a jar file that archives your PuzzleMenu.class file along with the other two classes I provided. You must also use the manifest file in the meta-inf folder to create an executable jar file. The jar file must be called <username>_assg1.jar, where username is your username. 14) Test your executable jar file and then submit only the jar file. I will be testing it first by double clicking on it to run the program. Assignment 2: 1) Creating database tables using Microsoft Access. 2) Setting the data source name by opening Control Panel\Administrative Tools\Data Source (ODBC) in Windows OS. 3) XML files and the role of DTD files. 4) XML Validators. 5) Java API for XML Processing (JAXP) and how it works with XML DOM. 6) Java Database Connectivity (JDBC) and how it can be used to communicate with databases. 1) Web Programming with Java notes on Database overview, SQL and JDBC. 2) W3Schools.com tutorial on SQL. 3) XML Notes and XML code examples. 4) XML and JAXP tutorials from External Links.

3 1) Design a database table relevant to your final project that has at least four fields (not the user login table). You need not design the entire database for the project now. 2) Then create this table using Microsoft Access calling the file assg2.mdb. The table name should be Assg2. You create another table with same fields in a different order, calling this table Assg2T2. Set up the data source name (DSN) to be xmltest (all lowercase). 3) See ODBC configuration information for setting up the database source name. 4) Then create a DTD file called assg2.dtd that describes the structure of this table for converting it into an XML file. See posted XML code examples. 5) Then create a Java program using the JDBC and JAXP APIs that will convert the table Assg2 into an XML file called assg2.xml that confirms to the DTD file that you created. 6) The JAXP program should ensure that the xml file can be viewed from textpad with proper line breaks and indentations. 7) Then create another Java program using again the JDBC and JAXP APIs that reads the information from this XML file and places values into the second table in the file Assg2T2. 8) Make sure that you use the JAXP and DOM API in creating the xml file as well as in reading the xml file for the second part. 9) Then create a folder whose name is your username. Place all the.java,.class,.mdb, and.dtd files into this folder. 10) Then run the programs from here, testing everything and making sure that the xml file is also created in this folder. View the xml file from textpad also. Try placing 3-4 records in the Assg2 table and then converting into xml file. 11) Create a zip file (NOT jar file) of this folder and its contents. So if I unzip it, it must create this folder. Call the zip file as username_assg2.zip where username is your actual username. 12) Then submit in the drop box for this course, by the due date. 13) Do not hardcode absolute paths for your files. If you do, they will not work for me. All paths must be relative to the root folder they sit in. Assignment 3: 1) XHTML code for creating web pages, CSS code for separating formatting commands in the web pages, JavaScript programming for a) dynamic web pages, b) client side processing of form validation and c) event handling of various HTML tags. 2) Tomcat installation and configuration. 3) Java Server Pages for server side processing of forms and returning a new web page to the client. 1) Web programming with Java notes on HTML, CSS, JS, JSP and Tomcat server. 2) HTML, CSS, JS and JSP code examples. 3) W3Schools.com tutorials on HTML, XHTML, CSS and JavaScript. 4) JSP tutorials posted at External Links. 5) Tomcat installation and configuration instructions.

4 1) Create an attractive web page relevant to your final project that contains a form that users need to complete. The form must include a text field, a password field, radio buttons, a checkbox, a dropdown box and a field for address. 2) This page must be created using a text editor and not HTML editors such as composer and Dream Weaver. You can however use the program Kompozer. 3) All the formatting commands in the HTML must be handled by a separate CSS file. See posted code examples. There should be no style attribute under any HTML tag. 4) When the user clicks the submit button, the page must go for validation by JavaScript. JavaScript source file must be a separate file from this HTML file. 5) The JavaScript validation must ensure that none of the entries are left blank. 6) Must also verify that the address has the correct format. 7) If there are errors, a JavaScript alert message must be displayed asking to correct the mistakes. 8) If there are no errors, a JavaScript alert message must come up thanking the user for the information and that the form is sent for processing. 9) In addition to the Submit button, the form must also have a Reset button, which will simply reset all the values in the form to blank. 10) The form must be sent for processing by JSP. 11) The JSP must generate a new attractive HTML page for display which will summarize all the information provided by the user. 12) See the web programming notes for JSP concepts. 13) Send this page back to the client browser for display. 14) Compress the HTML, CSS, JS and JSP pages and submit via blackboard. Do not hardcode any absolute paths. Assignment 4: The purpose of this assignment is to create the database for your project and finish the project. Follow the steps below in the order listed. 1) Database design, particularly for your final project. 2) Primary key: - a field in a table whose value uniquely identifies a single row (record). 3) Foreign key: - a field with possibly multiple rows with same value in a table but also corresponds to a primary key in a different table. Used to link the data from the two tables. 4) Normal forms used to divide the information into multiple related tables to minimize data redundancy. 5) Entity-Relation diagrams used to further reduce redundancy in the cases of many-tomany relationships. 1) Web programming with Java notes on all the database concepts. 1) Create a single MS Word document after doing the following and submit as pdf file along with the rest of the project.

5 2) Think of all the attributes that you need to store information about in a database for your final project. List them as a single list in the file to submit. Make sure you thought of all the attributes you will be using in the database, and also that you do not list items that you will do nothing with, in your project. For instance, if your project will not have an interface to use the gender value, do not collect that information. 3) Identify and list all the partial and transitive dependencies (if any exist. I will be surprised if none exists). You need not report this to me. 4) Use normalization to identify the entities and attributes. List the tables identified in each of 1NF, 2NF and 3NF, underlining the primary keys in each table. See the notes on how I did this with an example. You need to submit the same way. 5) Consider the relationships between entities and classify each as 1-1, 1-n or n-m (manyto-many). For instance a book and author are two separate entities because you want to store information about each. The relation between the book entity and the author entity is many-to-many because a book may be associated with many authors (i.e. written by), and an author may be associated with many books (i.e. wrote). 6) In case of many-to-many relationships, introduce an intermediate entity. 7) Draw and submit the E-R diagrams after breaking all the many-to-many relations as shown in the notes. Your E-R diagrams must resemble what I have in the notes. In particular, no cluttering of attribute lists in the E-R diagram as you may find online on some old versions of E-R diagrams. 8) Each entity must have one attribute called its ID, which will serve as the primary key. List all the attributes for each entity that would correspond to fields in your database. Using the naming conventions for the attributes: entity_attribute (for example book_id). You may also use the notation b_id or bookid for names. Be consistent with the rule you use for the naming of the attributes. Use class diagram model with Entity name as the top section, primary key (underlined) followed by attributes of the entity as the second section and foreign keys in the third section as in the example below. These tables (as standalone) must be submitted for all the entities in your final list of entities. Book Book_ISBN Book_year Book_edition Book_pages Publisher_ID Please note that the remaining part of this assignment is listed under Final project below. You must proceed to it after you complete this. Final Project Final project must be submitted via digital drop box by the deadline. N.V.R. Mahadev Page 5 4/15/2012

6 Since I need to configure my computer to run your project, you need to very clearly follow the instructions below. You need to use Microsoft Access database. The project must be created and submitted as follows: 1) Root directory for the application must be called MyJSP. 2) Create the folders WEB-INF, src and db under the root directory. 3) In addition create a folder called classes under WEB-INF folder. 4) Your database file will be located in the db folder and will be called finaldb.mdb. 5) The data source name (DSN) for your database must be finaldb. 6) The src folder will contain source files used to create Servlets and JavaBeans. 7) The compiled class files of all your Servlets and Beans reside in the classes folder. Make sure that package statement is used in the source code of the JavaBeans and the Bean class files reside in a subdirectory by the package name. 8) See the code examples provided. 9) Root directory will contain all your JSP, JS, CSS and HTML files. 10) The application must use a file named index.html or index.jsp as the starting point. 11) Create a web.xml file in the WEB-INF directory as required for Servlets and Beans. 12) Make sure that the program works with this set up. Note that your Tomcat must be configured to recognize the MyJSP folder. 13) Include the pdf file of the database design under the root directory of your project folder. 14) Compress the entire directory structure of MyJSP into a file called <username>_final.zip where <username> is replaced with your username. 15) Submit the zip file through the digital drop box before the Final day of classes.
