我需要对此进行清楚的解释,即使我读到这个关于差异的链接但没有明确的清晰度.所以任何人都可以用代码向我解释这一点.

在下面的代码中,如果recordset.size()为Zero,则创建一个Employee对象.那么有没有办法限制,所以如果recordset.size() >零,它只需要创建Employee对象.

ArrayList recordSet = new ArrayList();
//fetching data from database and keeping that many number of records in **recordSet**
.....
...DB related code...
.....
recordset.add(records); //'records' contain details of particular number of rows
//Based on number of returned rows from database object is creating
Employee[] emp = new Employee[recordset.size()];
