[PUB] Does RPE Studio supports ArrayList, HashMap (Collections)

//ElementsList and TypesMap are template variable
if (ElementsList == null || ElementsList == ""){
    ElementsList = new java.util.ArrayList();
}

TypesMap = new java.util.HashMap();
TypesMap.put("Type1", new java.util.ArrayList());
var val = TypesMap.get("Type1");

 You can use array of objects.

var obj = new Object();

obj['name'] = 'Tom';

obj['surname'] = 'Smith';

var array = [];

array.push(obj);

javascript des not support ArrayList or HashMap.
