java - Single used class vs. 'static class' -


i have program handles different objects have own sort of instructions set (say own program), , main class want run these programs. have 2 choices:

  • make class instructionhandler, create instance of in main class , pass requests 1 object [singleton pattern - mark peters]
  • make class instructionhandler static methods , make use of these in main class

what way go software - design point of view?

have considered using interpreter pattern? can instruction sets combined each of objects create kind of grammar?
