本文整理了Java中ucar.unidata.io.RandomAccessFile.readShort方法的一些代码示例，展示了RandomAccessFile.readShort的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。RandomAccessFile.readShort方法的具体详情如下：
包路径：ucar.unidata.io.RandomAccessFile
类名称：RandomAccessFile
方法名：readShort

RandomAccessFile.readShort介绍

[英]Reads a signed 16-bit number from this file. The method reads 2 bytes from this file. If the two bytes read, in order, are b1 and b2, where each of the two values is between 0 and 255, inclusive, then the result is equal to:

(short)((b1 << 8) | b2)

This method blocks until the two bytes are read, the end of the stream is detected, or an exception is thrown.
[中]从该文件中读取有符号的16位数字。该方法从该文件中读取2个字节。如果按顺序读取的两个字节分别为b1和b2，其中两个值均在0和255之间，则结果等于：
(short)((b1 << 8) | b2)
此方法会一直阻塞，直到读取两个字节、检测到流结束或引发异常为止。
