code view.java I did not write this code, it is aut. generated

  switch (flags & VISIBILITY_MASK) { case INVISIBLE: if (numFlags > 0) { output += " "; } output += "INVISIBLE"; // USELESS HERE numFlags++; break; case GONE: if (numFlags > 0) { output += " ";//тут ругается } output += "GONE"; // USELESS HERE numFlags++; break; default:
