// fetch query result

QueryResult result = query.execute();

Now we can get result in an iterator of nodes:

NodeIterator it = result.getNodes();

or we get the result in a table:

// get column names

String[] columnNames = result.getColumnNames();

// get column rows

RowIterator rowIterator = result.getRows();

while(rowIterator.hasNext()){

   // get next row

   Row row = rowIterator.nextRow();

   // get all values of row

   Value[] values = row.getValues();

}
