I have a big `String` that was once converted to a `ByteBuffer` & then while reading later several times, only a portion of the `String`(overview of the text) needs to be presented, so I want to convert only a part of the `ByteBuffer` to `String`. 

Is it possible to convert only a part of bytebuffer to string rather than [converting entire `Bytebuffer` to `String` & then using `substring()`]
