包路径：java.io.RandomAccessFile
类名称：RandomAccessFile
方法名：readUTF

RandomAccessFile.readUTF介绍

[英]Reads a string that is encoded in DataInput from this file. The number of bytes that must be read for the complete string is determined by the first two bytes read from the file. Blocks until all required bytes have been read, the end of the file is reached or an exception is thrown.
[中]从该文件读取DataInput中编码的字符串。完整字符串必须读取的字节数由从文件中读取的前两个字节决定。块，直到读取完所有必需的字节、到达文件结尾或引发异常为止。
