Question

I have a class that basically parses a file and stores results in a hashmap , this class should handle all files in a directory (usually <10 files) . The process is linear with a single thread.

for the sake of best practice, should it be a static or dynamic class ?

Answer 1

If calling your parsing method makes sense even when no ‘object’ has been created and initialized, use a static method

ie: do not use

Parser p = new Parser();
HashMap result = parser.parse("directory");

When you can easily do the following:

HashMap result = Parser.parse("directory");

Java: when to use static methods
