问题描述
我是java的新手,我试图创建XML文档并一遍又一遍地克隆此文档的特定节点(减去textnode)。有人回答了我,说我应该继承节点的子类并覆盖克隆。所以我的问题是什么是子类化?
I am new to java and I am trying to create an XML document and clone a specific node (minus the textnode) of this document over and over again. Someone answered me and said that I should subclass the node and override the cloning. So my question is what is sub-classing?
推荐答案
@Charlie Martin解释了子类化的含义。

但是,不清楚您是否得到了很好的建议。如果要通过在内存中组装DOM来创建XML文档,则更好的方法是使用静态方法创建一个助手类,该类执行需要执行的DOM节点操作序列。
However, it is not clear that you've been given good advice. If you are creating the XML document by assembling a DOM in memory, a better approach would be to create a helper class with static methods that perform the sequence of DOM node operations that you need to do.
