使用BufferedReader的readline()方法可以实现从输入流中逐行读取数据,并将每行数据存储到ArrayList中。下面是一个完善且全面的答案: readline()方法是BufferedReader类中的一个方法,用于从输入流中读取一行数据。它返回的是一个字符串,表示读取到的一行数据。在使用readline()方法之前,需要先创建一个BufferedReader对象,并...

In general, each read request made of a Reader causes a corresponding read request to be made of the underlying character or byte stream. It is therefore advisable to wrap a BufferedReader around any Reader whose read() operations may be costly, such as FileReaders and InputStreamReaders. Fo...
