Why RandomAccessFile uses int as an offset

Question

I am writing some implementation of a data access test, and I need random access to the contents of the file. Here is the code:

RandomAccessFile randomAccessFile = new RandomAccessFile(file, "rwd");
final byte b[] = IOUtils.toByteArray(source);
randomAccessFile.write(b, (int) offset, size);

where offset is of type long. Why does the RandomAccessFile method not provide a method:

public void write(byte b[], long off, int len)

?

How to override this problem?

Answer 1

I think you are looking for a method seek.

The offset in writeis the offset in the array. Arrays have offsets int. There were suggestions for "long arrays", but if they were implemented, you still need overload.
