Naming Conventions

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.
