java - FileChannel 位置(long newPosition) 是否为 0 索引？

Question

也就是说，如果我这样做:

channel.position(0)
channel.read(buffer); // will read in 1st byte of file and so on

对比

channel.position(1)
channel.read(buffer); // will read in 2nd byte of file and so on

我的假设正确吗？正在阅读the documentation并没有真正提到这一点，所以我想确定一下

Answer 1

Is FileChannel position(long newPosition) 0-indexed?

是的。

Reading the documentation doesn't really say anything about that so I wanted to make sure

我很清楚。 javadoc对于 position() 说:

"Returns: This channel's file position, a non-negative integer counting the number of bytes from the beginning of the file to the current position".

“[A]非负整数”表示零或更大。如果他们的意思是一或更大，他们会写“正整数”或“严格正整数”。
