Java - Object Oriented Programming Concepts
0 likesâ˘59 views
The document discusses object-oriented programming concepts. It explains that object-oriented programming involves modeling programs around real-world objects rather than procedures. This approach defines objects that contain both data and behaviors, and allows for data encapsulation. The document contrasts object-oriented programming with procedure-oriented programming, noting that the former emphasizes data over procedures and combines data and methods into objects.

- 2. Programming Language ďŽ A programming language is a computer language programmers use to develop applications ďŽ set of instructions for a computer to perform specific tasks. ďŽ The commonly used programming methodologies are: ďŽ Procedure-oriented programming ďŽ Object-oriented programming (OOP) 2Dr. P. Victer Paul, Indian Institute of Information Technology Kottayam
- 3. Procedure-oriented programming ďŽ Involves dividing a large program into a set of sub- procedures or subprograms that perform specific tasks. ďŽ Module consists of single or multiple procedures. ďŽ Most of the data is shared as global that can be accessed from anywhere within the program. 3Dr. P.

- 16. Procedural vs. Object-Oriented S. No Procedural Programming Object-Oriented Programming 1 Emphasis on Procedures Emphasis on Data 2 Data is not hidden Data is hidden 3 Data and methods are separate Data and methods are combined using objects 4 Data can be accessed by external functions Data cannot be accessed by external functions 5 Top-down Approach in program design Bottom-up Approach in program design 6 Eg.
