Was soll dieser "Befehl" (es ist ja eben keiner) überhaupt machen?
Zeile 94

throwable;

Jetzt macht er garnichts -> ersatzlos löschen.

 

[Gast]

Wenn ich ihn lösche, kommt:


Unhandled exception type IOException
Unhandled exception type IOException
Unhandled exception type IOException
Unreachable code

 

[Beni]

Wenn du von einem Stream liest/schreibst, benötigst du ein Exception-Handling.

Entweder sagt du der Methode, dass sie IOExceptions weiterreichen soll (public void methode(...) throws IOException{...}) oder du machst selbst einen try-catch Block um die gefährliche Stelle:

public byte[] methode(...){
  try{
    // Normaler und gefährlicher Code
    ...
    return ergebnis;
  }
  catch( IOException ex ){
    ex.printStackTrace();
    // Fehler verarbeiten
    ...
    return ergebnis;
  }
}
