Question

In java I’m having an inputstream (maybe sequenceinputstream) containing more than one file. I want to separate those files using java. Is there any solution available in java?

Answer 1

The simple answer is: you can’t / shouldn’t.

The complicated answer: in case you are dealing with a SequenceInputStream, you can access the underlying streams using this reflection hack:

@SuppressWarnings("unchecked")
public static Enumeration<InputStream> split(final SequenceInputStream sis){
    try{
        Field streamsEnumField =
            SequenceInputStream.class.getDeclaredField("e");
        streamsEnumField.setAccessible(true);
        return (Enumeration<InputStream>) streamsEnumField.get(sis);
    } catch(final Exception e){
        throw new IllegalStateException(e);
    }
}

But I would be very careful about using something like this.
