day-11: The Importance of Naming Conventions in Clean Code

Let us recall the topics

1. Class: Logical Entity - Blue Print or Template - Company
2. Object: Physical Entity - Sample of Class - Employee
3. Method: Action - calculateSalary

More meaningful examples:
WHY:
Object: Real Time Entity / Physical Entity / Representation (Sample) of a class / Instance of a Class

Object: Combination of States and Behaviors:
Mobile:
State: நிலை - RAM, Processor, MP, Pricing
Behavior: - Call, Browse, Chat

Naming convention:
1) Class name should start with capital Letter
Eg. Calculator

2) Should Follow Camel Case
MyFirstJavaProgram, My_First_Java_Program

3) Should not start with Numbers
Eg. 2Calculator --> Calculator2

4) No Special Characters except _, $

5) MEANINGFUL NAME

6) Class Names should be Nouns, should not be Verbs.
Eg. Browser, Browse is not correct.

Object Name: Meaningful
Calculator calculator = new Calculator();

Datatypes: தரவுவகை
-> mp3,mp4, pdf, doc, xls --> Binary (0,1s)

1 Bit: Binary Digits (0,1s)
1 Byte: 8 Bits:

String is a class.
int, float, boolean - Not classes

Example Programmes:

1). Theatre as Class

public class Theatre { int ticket_fare; //int float show_time; //float String screen; //String boolean on_screen; //boolean public static void main(String[] args) { Theatre theatre = new Theatre(); theatre.playShow(); // } public void playShow() { System.out.println("Dar"); } } 

2). School as a Class

public class School { int no_students; //int float timing; //float String name; //String boolean open; //boolean public static void main(String[] args) { School school = new School(); } } 

3). Bank as Class:

public class Bank { int amount; //int float interest_rate; //float String name; //String boolean open; //boolean public static void main() { Bank bank = new Bank(); } } 

By following proper naming conventions and structuring your classes, objects, and methods effectively, you create clean, readable, and maintainable code that will stand the test of time.

Happy Learning...
