Java ByteArrayOutputStream into a different container

Can ByteArrayOutputStream be stored into some other container like say HashMap?

If not how do I merge all my streams and then zip archive by entries into 1 file.

public class CFr { 

  private static HashMap<String, Object> fileEntries;

  public static void setFileEntries(String fileNameEntry, Object fileEntry) {
    CFr.fileEntries.put(fileNameEntry, fileEntry);
  }

}

public void addDocx(CDb cd) {
  CFr.setFileEntries((String)entryName, (ByteArrayOutputStream)bos);
}

And I get NullPointer on that setFileEntries line. Doesn't seem right, I was just assuming it is possible.

Yes, it can be stored, but you will need to initialize your HashMap for that purpose. In your case this

  private static HashMap<String, Object> fileEntries;

is never initialized. You will need to do something like this:

private static HashMap<String, Object> fileEntries = new HashMap<String, Object>();

instead. This will fix your current issue.
