LinkedHashMap provides two capabilities that are not available with LinkedHashSet. When you create a LinkedHashMap, you can order it based on key access rather than insertion. In other words, merely looking up the value associated with a key brings that key to the end of the map. Also, ...
This example doesn't work because GSON uses a TreeMap, so the right example would be to do myLinkedHashMap.put("3", "third"); and myLinkedHashMap.put("1", "one"), so you would see that GSON flips the results.. –Rafael Sanches Commented Mar 11, 2019 at 17:20 | Show 1 ...

(when you iterate through it), then HashMap is the right choice. Keys of HashMap is like Set means no duplicates allowed and unordered while values can be any object even null or duplicate is also allowed. HashMap is very much similar to Hashtable only difference is Hashtable has all ...
