jchq I/O question

[Bing Lu]

Can any1 tell me why all the selections are correct?
I'm wondering about 2) & 3)
thanks
Which of the following statements are true?
1) Java can display character sets independently of the
underlying operating system
2) The InputStreamReader may take an instance of the
RandomAccessFile class as a constructor
3) An InputStreamReader may act as a constructor to an
OutputStreamReader to convert between character
sets
4) Java stores text internally as Unicode escape strings

Hi Bing,
2. I'm not sure about this either. On the surface, doesn't look as if it would be true since InputStreamReader ctor's take InputStreams and RandomAccessFile does not inherit from InputStream.
3. There is no OutputStreamReader class, only OutputStreamWriter. At least that's the only one I could find in the JDK 1.3 docs.
