Sample Questions1. a. Write a java program to perform the arithmetic operations using the concept of

method overloading

Get two inputs Integer and the output must be a float.

Get two inputs Float and the output must be an Integer.

Write a java program to perform the concept of method overriding for calculating

simple interest of 3 banks A,B,C. using dynamic method dispatch

Bank A’s rate of interest-10%, Bank’s B rate of interest-9%, Bank’C rate of

interest -7%

Design the HTML page for a job site which contains a form for filling a biodata

of a person and it should contain a menu of various train lists

2. Write a RMI program to perform arithmetic operations. Based upon the user

choice the operation must be performed

3. Write a java program to find the roots of a quadratic equation using interface and

packages.

Declare a interface in package Quad1

Declare another package Quad2 and implement the interface.

4. Develop a simple JDBC application to store the details of an employee in a table

and retrieve it and display it in the console

Design a Web page which contains information regarding your college which

contains tables, lists and hyperlinks. (Must use attributes)

5. Write a java program to throw a exception (checked) for an employee details

If an employee name is a number, a name exception must be thrown.

If an employee age is greater than 50, an age exception must be thrown.

Or else an object must be created for the entered employee details.

6. a. Write a TCP/IP Socket program to send the contents of a file from server to

client.

b. Design a HTML page for railways which contains link for a reservation and

viewing various train details.

7. Write a java program to perform the following operations based upon the choice

entered by the user.

its attributes, a form for issuing a book to students and use various type of lists to

display the book details .

11. Develop a web page which contains information regarding job opportunities using

tables ,lists ,forms and basic HTML tags

Get the biodata of the user as an input using various form fields (the form must

have all the controls) and on submission of the form, a servlet is invoked to

display the data in tabular column

12. a. Write a java program to calculate the area of 3 geometric objects operations

using the concept of method overloading.

b. Write a java program to perform the concept of method overriding for

calculating simple interest of 3 banks A, B, C. using super mechanisms
