本文整理了Java中ucar.unidata.io.RandomAccessFile.skipBytes方法的一些代码示例，展示了RandomAccessFile.skipBytes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.skipBytes方法的具体详情如下：
包路径：ucar.unidata.io.RandomAccessFile
类名称：RandomAccessFile
方法名：skipBytes

RandomAccessFile.skipBytes介绍

[英]Skips exactly n bytes of input. This method blocks until all the bytes are skipped, the end of the stream is detected, or an exception is thrown.
[中]完全跳过n字节的输入。此方法会一直阻塞，直到跳过所有字节、检测到流结束或引发异常为止。

 raf.skipBytes(skip);
 return raf.readFloat();
}
