something like this would be sufficient

while (retry < MAX_RETRY) {
    if (istream.hasNext()) {
        // read stream
        retry = 0;
    } else {
        sleep(1000);
        retry++;
    }
}

your logic for checking if the input is present might be different
but the general concept should be similar
