Kindly note that answers for 10 marks questions should be approximately of 400 words. Each question is followed by evaluation scheme. Q. 1 Write down what the following tags will perform a. <table> b. <td width> c. <embed> d. <a> e. <object> Ans : a. <TABLE> - AllowsyoutoAligntextintables.You can see an example of this on our Support page. How you do this is start with <Table> and if you want borders, just use the below commands. Example: <TABLE ALIGN="center" b. <TD> - Used to define each cell part of the table. See table page for additional information and examples on tables. c. <EMBED> : You use the embed tag to deploy applets that are to be used only with the Mozilla family of browsers. Following is an example of the embed tag:
- 2. d. <A> -HTML tag that allows aspects of your web page to be anchored, such as a link <A HREF= "Http://www.computerhope.com e. <OBJECT> We use the object tag to deploy applets that are to be used only with Internet Explorer. For complete detailsonthe objecttag, read the W3 HTML specification. Following is an example of the object tag: Q. 2 Write short notes on a. Web browsers Ans : A web browser (commonly referred to as a browser) is a software application for retrieving, presentingandtraversinginformationresourcesonthe WorldWide Web.Aninformationresource is identifiedbyaUniformResource Identifier(URI/URL) andmaybe a webpage,image, video or other piece of content. Hyperlinks present in Q. 3 Write a programme to create a webpage that prints the name of the STUDENT database in Wide Latin font and set the subtitle with description of the STUDENT to the screen. Set the page layout to the webpage. Insert one image after the database with a Thank you note. Ans : There are basicallytwowaysto make a webpage.The firstway isto create the page(s) offline and then upload them to your Internet Service Provider (ISP) via FTP. The second way is to create your webpage(s) online using a Telnet program by accessing your UNIX account, if you have one. If you are creating your web page(s) offline, do Q.4 Read the following case study thoroughly and answer the following questions: ABC is an educational institute which is reputed for its management courses. It has 3 branches in different places and is planning to launch 2 more branches in some other places. The institute used to maintain the student details in the form of a hard copy file. One day, a fire broke out in the record section and all such records were destroyed. Next day the management decided to maintain the student detailsin a computer so as to preventthe damage due to such disasters. One of the management members suggested that XYZ Company is capable of developing a kind of applicationfor maintaining records usingjava. The member further told other members that in his friend’s organisation the same java application developed by the sXYZ company was working very effectively and it also offered enough security parameters. Immediately the management appointedan employee whohad goodknowledge of java language to oversee the implementation of the required application. That employee prepared an outline of the company’s requirements and submitted it to the XYZ Company. The requirements of institute were: For institute’s employees–student details, course details, materials, and access rights. For students it was– Course material, feedback on assignments, course details and faculty details. XYZ company’s webdesignersdevelopedaprototype of an applicationbased on the requirements of the ABC institute. Now the programmers of XYZ company detailed the process of application developmentbasedonthe specifiedrequirements.Theydecidedthat for display purpose they can use JSP (Java Sever Pages) and to retrieve the details of a particular student, they would create
- 3. JDBC connection to the all branches. The student details can be stored in a database table (server side) by using MySql. They also decided to use servlets for internal process. That is, sending of request and obtaining response from the server. After developing the application, they submitted it to ABC institute for testing purpose. During the testing process, it was found that there is no proper security mechanism in the application. That is, the application permitted ‘Login’ by every member. So ABC company asked XYZ company to install security mechanism in the application such that it gives separate access to the employees and students. XYZ company modified the application by giving only limited and absolutely necessary access rights to the concerned users. Also a new security parameter added to the application, prevented access by a user for 24 hours if he/she entered incorrect ‘Login’ details for three consecutive times. a) Give reasons as to why ABC institute decided to choose XYZ Company for the development of Java application. Ans : ABC institute decided to choose XYZ for the development of Java application because the institute understood the importance of e-records. As it had already faced the problem in keeping hard copyof records.XYZ organisationwaswell efficientindevelopingjavabasedsoftware so it was chosen. Other important reason was maintenance of records . It is very essential to keep records safe. Each school has a responsibility to maintain its records and record keeping systems. Although schoolswill have their own methods of creating and keeping records and sharing information with staff,students,parentsandthe general public,theyshould be aware that, in doing so, they need to take account of matters such as b) Discuss the reason for using JSP in java application. Ans : Java Server Pages (JSP) is a technology that helps software developers create dynamically generated web pages based on HTML, XML, or other document types. Released in 1999 by Sun Microsystems, JSP is similar to PHP, but it uses the Java programming language. To deploy and run Java Server Pages, a compatible web server with a servlet container, such as Apache Tomcat or Jetty, is required. Advantages of JSP Hosting: Developers can easily maintain web pages with Q. 5 For the above case study answer the following questions a. State the reason for using database connection in the application. Ans : Database connection is the means by which a database server and its client software communicate with each other. The term is used whether or not the client and the server are on differentmachines.The clientusesadatabase connectiontosendcommands to and receive replies from the server. A database is stored as a file or a b. Explain the purpose of creating a java application for the ABC institute. Ans : 1. It is clear from above discussion that java application is important for ABC institute for keeping and maintaining its record and to collaborate with its other branches. Manual record maintenance is very tedious job and is not reliable.
- 4. 2. With the help of this application , staff and students can now take information directly by just logging into the webpage of the institute. Q.6 How do you handle exception in java? Give with an example. Ans : A Java exceptionisnothingbutanobjectthat definesanexceptional condition,oranerror that has occurred in a piece of code. In Java, we can handle this exception by creating an object that represents the exception, and throwing that object into the method that triggered the error. There are two ways by which exceptions can occur. They are as follows: 1. Java run-time system:These exceptionsrelate tothe fundamental errors that violate the rules of the Java programming language or the constraints of the Java execution environment. 2. Code generated: The code that we write can manually generate exceptions. These are used to report some error condition to the caller of a Dear students get fully solved assignments Send your semester & Specialization name to our mail id : “ help.mbaassignments@gmail.com ” or Call us at : 08263069601 (Prefer mailing.
