Time: 3 Hours Max Marks: 70
Answer ONE Question from each Unit
All Questions Carry Equal Marks
All parts of the question must be answered in one place only
UNIT I
1. What are class and object? Give the syntax for class and object creation.
Create a class Student with rno, name, branch.
i. Include a parameterized constructor to initialize Student objects.
ii. Include a static method which accepts an array of students and prints them.
iii. Write a test program to create an array of students and then call the above method to print
them.
2. What are static fields and methods? Write an example code snippet for the same.
Create a class Employee with fields name, designation and salary.
i. Include a parameterized constructor to initialize the object.
ii. Include overloaded method to hike the salaries of employee. Salary hike can be specified by
an amount or percentage.
iii. Write a test program to create few employee objects and invoke above mentioned methods.
UNIT II
3. What is Inheritance? Write a program for achieving multilevel inheritance.
What is the significance of abstract keyword? Explain with an example program and also how
it is different from a final keyword.
4. What is a package? Create one class in one package and one interface in another package and
show how they can be utilized in a target main class.
What is method overriding? Write one example program for it also targets runtime polymorphism.

UNIT III
5. What is an exception? Explain the key words that are going to be used while doing exception
handling.
Explain the situations where multiple exception handling will be done, and also explain the role
of Exception class in those situations.

File operations.
Write a program that analyzes number of alphabets, numbers, special symbols, lines and words
in a file.
8. What are the various steps involved while implementing a JDBC program? Explain with proper
code segments.
Write a program that inserts some records of students into Student table containing the details
RollNumber (varchar), Name (varchar), MobileNumber (number) and Percentage (number
using prepared statement. Also display the student records who got first rank in the class.

UNIT V
9. What is an Applet? Create a sample applet program that displays a message
Explain any five AWT(Abstract Window Toolkit) components.
