It depends on the problem. This is really only something you can answer with experience, but one good guideline is that using objects is useful when you have a collection of logically-contained behavior. If you can point at an entity in the solution and say "Here is an individual thing that does several related things", you might have a good candidate for an object.

Use:  <p> text here (a paragraph) </p>

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
