any processing. It can be regarded as a killer in Java programming. In terms of the frequency and severity of the problem, it may be comparable to that of the C/C ++ program ?? Do not check whether the buffer zone is full. If you see this discard (rather than throw) exception, you can be 99% sure that the code is faulty (in rare cases, this code has a reason, but it is best to add a complete comment to avo
