Java read text files tutorial shows how to read text files in Java. We use build-in tools including FileReader, InputStreamReader, and Scanner.
("foo.in"));will buffer the input from the specified file. 将会缓存指定的输入流. Without buffering, each invocation of read() or readLine() could cause bytes to be read from the file, converted into characters, and then returned, which can be very inefficient. 如果没有缓存,每次调用read(...
