How can I convert ZipInputStream to InputStream?


I have code, where ZipInputSream is converted to byte[], but I don't know how I can convert that to inputstream.

private void convertStream(String encoding, ZipInputStream in) throws IOException,
        UnsupportedEncodingException
{
    final int BUFFER = 1;
    @SuppressWarnings("unused")
    int count = 0;
    byte data[] = new byte[BUFFER];
    while ((count = in.read(data, 0, BUFFER)) != -1) 
    {
       // How can I convert data to InputStream  here ?                    
    }
}

Solution

  • Here is how I solved this problem. Now I can get single files from ZipInputStream to memory as InputStream.

    private InputStream convertZipInputStreamToInputStream(ZipInputStream in, ZipEntry entry, String encoding) throws IOException
    {
        final int BUFFER = 2048;
        int count = 0;
        byte data[] = new byte[BUFFER];
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        while ((count = in.read(data, 0, BUFFER)) != -1) {
            out.write(data);
        }       
        InputStream is = new ByteArrayInputStream(out.toByteArray());
        return is;
    }
