Object Oriented Programming Module 1-2

Object-Oriented Programming

about creating objects that contain both data and methods

Procedural programming

writing procedures or methods that perform operations on the data,

WHY OOP PROGRAMMING

faster and easier to execute, provides a clear structure for the programs, makes the code easier to maintain, modify and debug, full reusable applications with less code and shorter development time.

BASIC PRINCIPLE OF OOP

Abstraction, Encapsulation, Inheritance, and Polymorphism, There are also objects and classes.

Class

a blueprint or template for creating objects

object

a fundamental building block, self-contained unit that combines data (attributes) and the functions (methods) that operate on that data.

Programming Logic

a set of principles describes how elements shoud be arranged

Algorithm

Series of instructions, how to transfrom a set of facts about the world into useful information.

Computer Programming

set of instructions helps developer to perform certain tasks.

computer

machine that processes data that can be any information that is provided by the user.

Primary Memory / RAM (Random Access Memory)

accessed or modified quickly in any order or random, stored in RAM is lost when the computer is turned off.

Secondary Memory / ROM (Read-Only Memory)

stored in ROM is read-only and stored permanently, Stored instruction required to start a computer.

BASIC PROGRAMMING CONCEPTS

1. Algorithm

2. Source Code

3. Compiler

4. Data Type

5. Variable

6. Condtionals

7. Array

8. Loop

9. Function

10. Class

Algorithm

set of steps or instruction statements

Source code

actual text that used to construct program using the language of choice.

Compiler

software program that helps in converting source code into binary code or byte code, AKA (machine language)

Data Type

classification specifies which type of value a variable has.

Variable

space holder or a data holder for the value stored in the memory.

Conditionals

Knowledge of how to use a certain condition, A set of codes should execute only if a certain condition is true.

Array

variable that stores elements of a similar data type.

Loop

used to execute the series of code until the condition is true.

Function

Functions or methods are used to accomplish a task in programming, used to reuse them whenever required at any place repeatedly.

Class

Like Template that containe state and behavior

Java (Language)

Revolves around classes and objects
