Guidelines for Naming Conventions

Guidelines for Naming Conventions

1. Use Plural Names for Collections:
   When naming collections (lists, arrays, etc.), use plural nouns to indicate that the variable holds multiple items.

   // Good List<Integer> connectionIDs = new ArrayList<>();

   This makes it clear that connectionIDs is a collection of multiple Integer values.

2. Avoid Prefixing with "List" or "Array":
   Do not prefix collection names with words like "List" or "Array" unless it improves clarity.

   // Bad List<Integer> listOfConnectionIDs = new ArrayList<>(); // Good List<Integer> connectionIDs = new ArrayList<>();

   Using prefixes like "listOf" can add unnecessary verbosity and reduce readability.

3. Use Descriptive and Meaningful Names:
   Choose names that clearly convey the purpose and contents of the collection.

   // Good List<String> customerEmails = new ArrayList<>(); // Good Set<Long> activeUserIds = new HashSet<>();

   This helps anyone reading the code understand what kind of data the collection holds.

4. Be Consistent with Naming Style:
   Maintain consistency in naming conventions throughout your codebase. If you use plural names for collections in one part of your code, continue to do so across all similar contexts.
