假设我有这个代码,它将“主题”添加到充当组织者的应用程序中。如何编写用户在txt文件中输入的内容,如果可能需要进行某些编辑,将再次读取该内容以编辑原始输入。我试着搜索如何将数据存入文件,但我失败了。我希望你能帮助我。谢谢。

答案 0 :(得分:1)
有很多选择它并不好笑......
使用Properties
存储key = value对,提供store
和load
方法,以便于读取和写入
使用允许存储分层数据的XML文件,虽然比Properties
更灵活,但会增加复杂性
有关详细信息,请参阅Java API for XML Processing (JAXP)。
您还可以使用JAXB(Java Architecture for XML Binding),它可用于在基于XML的结构中存储对象属性。请查看Introduction to JAXB了解更多详情......
只需滚动自己,将文本写入您想要的任何格式的文件。有关详细信息,请参阅Basic I/O
