Java Naming Conventions:

• Naming convention refers to a set of standardized rules and guidelines for naming classes, methods, variables, and other identifiers to ensure code readability and maintainability.
• Below table shows an example of naming convention in java :

  Naming	Single Word	Two Words	Three Words
  Classes, Interfaces	Example	MyExample	MyExampleDemo
  Methods	example()	myExample()	myExampleDemo()
  Variables	example	my_example	my_example_demo
  Constants	EXAMPLE	MY_EXAMPLE	MY_EXAMPLE_DEMO
  Packages	example	my.example	my.example.demo

• Key Notes for Each Category:
  1. Classes and Interfaces:
     • Use PascalCase (capitalize the first letter of each word).
     • Example: MyClass, UserAccount.
  2. Methods:
     • Use camelCase (first word lowercase, subsequent words capitalized).
     • Always name methods as actions or verbs.
     • Example: getDetails(), calculateTotal().
  3. Variables:
     • Use camelCase for instance variables and local variables.
     • Separate words with an underscore (_) only when necessary.
     • Example: user_age, total_price.
  4. Constants:
     • Use UPPER_SNAKE_CASE (all uppercase, words separated by underscores).
     • Example: MAX_VALUE, DEFAULT_TIMEOUT.
  5. Packages:
     • Use lowercase letters with dots separating levels of hierarchy.
     • Reflect the project's domain or structure.
     • Example: com.example.project.
