Naming Conventions in Java

&npsp; &npsp; &npsp; &npsp; &npsp; &npsp;Java follows several naming conventions to promote consistency and readability in code. Here are some key conventions:

• Class:The class names should be in mixed cases, and the first letter of each word should be capitalized.
• Methods: The method names should be in mixed case, where the first word starts with a lowercase letter, and all subsequent words start with a capital letter.
• packages: The package names in Java are always written in all lowercase.
• Identifier: Here are the rules for creating valid identifiers in Java:
  • Must begin with a letter or underscore (_): The first character of an identifier must be a letter or underscore.
  • Subsequent characters can be letters, digits, underscores: After the initial character, you can use letters, digits, dollar signs, or underscores in your identifier.
  • Cannot be a reserved keyword: You cannot use Java reserved keywords (like int, class, if, etc.) as identifiers.
  • Case-sensitive: Java is case-sensitive: so myVariable and myvariable would be treated as different identifiers.
  • No spaces or special characters (Except underscore): Spaces and special characters are not allowed in identifiers.
