CS3391 - Object Oriented Programming Important Topics (Unit-wise)

Object oriented programming is a core subject for building strong coding and problem-solving skills in Java. Learning each unit clearly helps students answer both theory and programming questions with confidence in internal and university exams.

Unit I

This unit introduces the basic ideas behind object oriented programming and the foundation of Java syntax. Students should focus on understanding concepts and writing small basic programs.

  • Characteristics of object oriented programming
  • Data types in Java and variables
  • Arrays
  • Operators in Java and types of operators
  • Constructors and constructor overloading

Unit II

This unit is important for understanding code reusability and flexible program design. Practice class-based examples to clearly learn inheritance and method behavior in Java.

  • Interfaces
  • Inheritance in Java
  • Function overloading
  • Difference between overloading and overriding

Unit III

This unit covers error handling and concurrent program execution. It is frequently asked in exams through both conceptual questions and short coding problems.

  • Exception handling: try, catch, throw, throws, and finally
  • Nested try statements
  • Java built-in exceptions
  • Multithreading

Unit IV

This unit improves type-safe programming and text processing skills in Java. Questions often test understanding of generic syntax and common string manipulation methods.

  • Generic classes with examples
  • Generic methods with examples
  • String class basics and commonly used methods
  • StringBuffer class and mutable string operations
  • Programs for string comparison, searching, and modification

Unit V

This unit focuses on graphical user interface design and user interaction in Java. Students should practice small GUI programs with different events and layout controls.

  • Handling key and mouse events in Java applications
  • Menu
  • Layout: FlowPane, HBox, VBox, and BorderPane

Exam Preparation Tips

  • Prepare one-page revision notes for each unit with key definitions and syntax.
  • Practice at least two small Java programs from every unit before exams.
  • Write short differences such as overloading vs overriding and String vs StringBuffer.
  • Solve previous university questions to identify repeated concepts and important patterns.
  • Revise exceptions, multithreading, and GUI topics during the final week for better scoring.
