我需要帮助从输入文件中提取一个带有空格的字符串

我正在制作一个程序，该程序从输入文件中获取学生记录，并将其存储在arraylist中。我正在获取学生证，姓名和三个考试成绩。每个项目均由标签分开。我需要帮助将学生姓名一并列出。如果我这样运行它会搞砸，因为某些名称具有姓氏，名字和中间的缩写。为了详细说明我的主要问题，我正在尝试从文件中提取名称IE JA Singleton并将其放入我的arraylist中。我只是先获取名字，然后获取姓氏，然后将它们放在一起，但这并不总是可行的，因为其中有些需要抓住三个不同的东西，例如上面的示例。由于文件中名称的前后都有一个制表符，因此是否有办法只获取整个名称？
