DefaultListModelis a implementation of the ListModelthat extends from AbstractListModel.
DefaultListModel是ListModel从 扩展的的实现AbstractListModel。
Internally, it is backed by Listimplementation.
在内部，它得到List实施的支持。
It's intention is to provide a simple implementation of the ListModelthat you can use for modelling simple data models where having to extend from the AbstractListModelor implement the ListModelinterface would be overkill for accomplishing the same task
它的目的是提供一个简单的实现ListModel，您可以使用它来对简单的数据模型进行建模，其中必须扩展AbstractListModel或实现ListModel接口对于完成相同的任务来说是多余的
