Home Discussion Discuss: LinkedHashMap is Actually Quite Useful - Java Tutorials

  • LinkedHashMapSteve October 6, 2011 at 12:43 AM

    Regarding the great explanation of LinkedHashmap: I recently used it like this: LinkedHashMap<String, String> parameters = new LinkedHashMap<String, String>(); Then a series of 'put' statements were used to load the data. Reason I am pointing this out is that I don't see where this use fits into the "5 constructors" laid out in the article. Is this yet another use of the class?
