java - Custom string representation of a custom typed collection -

If I need a custom string representation of custom type collection, which is the best option - the collection is sub-class and ToString override (), or just create a utility method that takes custom typed compilation and gives a custom string? What is another option?

I would have to make a utility method. There are some reasons:

• Logically, your custom string representation is something that you are leveraging over the original class: it is not part of the original class. So this is not within the definition of the original class.
• Creating a subclasses is probably overkill for overriding a method
• Creating a custom subclass makes it impossible to work with an object that overrides the original class for a different reason Used to be. If you use heritage for things like this, you can easily mismatch in succession. Always like the structure of heritage!
• You can continue to use the original toString () for a few reasons: You probably need both string convergence or any other library depends on the original code

  You have one more option within the "Utility System" option: P>

  • Make a simple static utility method simple, quick, this may be your first choice.
  • Create a "formatter" object with a method like
    formatter.formatAsString (targetObject) . This can be useful if you have some formatting options that you can store in the formator.
