             Summary: [Java] Implement a common interface for int vectors
                 Key: ARROW-5726
                 URL: https://issues.apache.org/jira/browse/ARROW-5726
             Project: Apache Arrow
          Issue Type: New Feature
          Components: Java
            Reporter: Ji Liu
            Assignee: Ji Liu


Now in _DictionaryEncoder#encode_ it use reflection to pull out the set method and then set values. 

Set values by reflection is not efficient and code structure is not elegant such as

_Method setter = null;_
_for (Class<?> c : Arrays.asList(int.class, long.class)) {_
 _try {_
 _setter = indices.getClass().getMethod("setSafe", int.class, c);_
 _break;_
 _} catch (NoSuchMethodException e) {_
 _// ignore_
 _}_
_}_

Implement a common interface for int vectors to directly get set method and set values seems a good choice.
