Naming Conventions

Part of the Fundamentals section of Coddy's Java journey — lesson 11 of 73.

In Java, it's important to follow naming conventions to keep your code readable and maintainable. Here are some key rules:

Variable Names:
- Use camelCase: Start with a lowercase letter, then capitalize the first letter of each subsequent word (e.g., firstName, studentCount).
- Choose descriptive names that indicate the variable's purpose (e.g., userAge instead of ua).
- Avoid single-letter names except for simple loop counters.

Constant Names:
- Use UPPER_SNAKE_CASE: Write in uppercase letters, with words separated by underscores (e.g., MAX_VALUE, PI_VALUE).
- Use for values that don't change throughout the program.

General Rules:
- Names can contain letters, digits, underscores, and dollar signs.
- Names must start with a letter, an underscore _, or a dollar sign $.

General Rules:
- Names are case-sensitive (myVariable is different from myvariable).
- Avoid using Java's reserved keywords (like int, class, public, etc.).

Following these conventions helps make your code more understandable, especially when working in teams or revisiting your code later.
