CS8392 Object Oriented Programming Previous Year Question Paper

OBJECTIVES:
 To understand Object Oriented Programming concepts and basic characteristics of Java
 To know the principles of packages, inheritance and interfaces
 To define exceptions and use I/O streams
 To develop a java application with threads and generics classes
 To design and build simple Graphical User Interfaces

UNIT I INTRODUCTION TO OOP AND JAVA FUNDAMENTALS 

Object Oriented Programming – Abstraction – objects and classes – Encapsulation- Inheritance –Polymorphism- OOP in Java – Characteristics of Java – The Java Environment – Java Source File – Structure –Compilation. Fundamental Programming Structures in Java – Defining classes in Java – constructors, methods -access specifiers – static members -Comments, Data Types, Variables, Operators, Control Flow, Arrays ,Packages – JavaDoc comments.

UNIT II INHERITANCE AND INTERFACES 

Inheritance – Super classes- sub classes –Protected members – constructors in sub classes- the Object class – abstract classes and methods- final methods and classes – Interfaces – defining an interface, implementing interface, differences between classes and interfaces and extending interfaces – Object cloning -inner classes, ArrayLists – Strings

UNIT III EXCEPTION HANDLING AND I/O 

Exceptions – exception hierarchy – throwing and catching exceptions – built-in exceptions, creating own exceptions, Stack Trace Elements. Input / Output Basics – Streams – Byte streams and Character streams – Reading and Writing Console – Reading and Writing Files

UNIT IV MULTI THREADING AND GENERIC PROGRAMMING 

Differences between multi-threading and multitasking, thread life cycle, creating threads, synchronizing threads, Inter-thread communication, daemon threads, thread groups. Generic Programming – Generic classes – generic methods – Bounded Types – Restrictions and Limitations.

UNIT V EVENT DRIVEN PROGRAMMING 

Graphics programming – Frame – Components – working with 2D shapes – Using color, fonts, and images – Basics of event handling – event handlers – adapter classes – actions – mouse events – AWT event hierarchy – Introduction to Swing – layout management – Swing Components – Text Fields , Text Areas – Buttons- Check Boxes – Radio Buttons – Lists- choices- Scrollbars – Windows –Menus – Dialog Boxes.
