Subject Code: 2150704 Date: 02/12/2019
Subject Name: Object Oriented Programming using JAVA
Time: 10:30 AM TO 01:00 PM Total Marks: 70
Instructions:
1. Attempt all questions.
2. Make suitable assumptions wherever necessary.
3. Figures to the right indicate full marks.
MARKS
Q.1 (a) Explain any three features of JAVA. 03
(b) What is a constructor in JAVA? How many types of constructors are
there in JAVA? Explain with examples.
04
(c) Write a JAVA program to implement the Fibonacci series using for
loop control structure.
07
Q.2 (a) Explain the use of final keyword in JAVA. 03
(b) What is a thread? Describe the complete life cycle of thread. 04
(c) Write a JAVA program to create a super class called figure that stores
the dimensions of a two-dimensional object. It also defines a method
called area () that computes the area of an object. The program derives
two sub classes from figure. The first is rectangle and the second is
Triangle. Each of these subclasses overrides area (), so that it returns
the area of a rectangle and a triangle respectively.

(c) Discuss various access modifiers available in JAVA? How access
modifier affects the visibility of a member in different access
locations?
07
OR
Q.3 (a) Explain garbage collection and finalization. 03
(b) Explain Super keyword with the help of example. 04
(c) Discuss the role of thread synchronization in inter-thread
communication? Explain with example.
07
Q.4 (a) Describe the following methods related to String
i) replace() ii) compareTo()
03
(b) How package can be created in JAVA? Explain with suitable example. 04
(c) Prepare a sequence diagram for hotel management system. 07
OR
Q.4 (a) Explain the following terms with respect to exception handling.
i) throw ii) finally
