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 ?
}
}

Answer

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;
}
