Java：fseek（），ftell（）等价于文本文件输入？

Question

How can I seek into a text file in Java? I'm processing a text-based journal file, and would like to checkpoint my work so that it can be resumed by a future invocation of my program.

I'm looking for something similar to C stdio fseek()/ftell() functionality.

RandomAccessFile gives you random access to a file (surprise, surprise :)) and its readLine() method allows you to process it line by line.

The current position can be queried by getFilePointer() and the seek() method seeks.
