How to read a file from a certain offset in Java?
提问by Khashayar
Hey I'm trying to open a file and read just from an offset for a certain length! I read this topic: How to read a specific line using the specific line number from a file in Java?in there it said that it's not to possible read a certain line without reading the lines before, but I'm wondering about bytes!
嘿，我正在尝试打开一个文件并从一定长度的偏移量中读取！我阅读了这个主题： How to read a specific line using the specific line number from a file in Java? 在那里它说不可能在不阅读之前阅读某一行的情况下阅读某一行，但我想知道字节！
FileReader location = new FileReader(file);
BufferedReader inputFile = new BufferedReader(location);
// Read from bytes 1000 to 2000
// Something like this
inputFile.read(1000,2000);
Is it possible to read certain bytes from a known offset?
是否可以从已知偏移量读取某些字节？

RandomAccessFileexposes a function:
RandomAccessFile公开一个函数：
seek(long pos)
Sets the file-pointer offset, measured from the beginning of this file, at which the next read or write occurs.
