 [JAVA]Prog.io della minchia!

Ho scaricato Jcreator per poter scrivere in java...
Il problema è che sebbene gli abbia dato come package il prog.io che serve per far girare delle classi particolari, mi da l' errore:

C:\Documents and Settings\programmi\MediaVotii.java:5: cannot access prog.io.ConsoleOutputManager
bad class file: C:\j2sdk1.4.1_02\lib\prog.jar(prog/io/ConsoleOutputManager.class)
class file has wrong version 49.0, should be 48.0
Please remove or make sure it appears in the correct subdirectory of the classpath.
ConsoleOutputManager video = new ConsoleOutputManager();


Ma se gli ho detto di usare il package prog.jar che contiene quelle classi dove sta il problema???

:(:(:(:(:(:(:(:(:(:(

probabilmente la classe in questione è stata compilata con jdk superiore, prova a ricompilare il sorgente con il tuo jdk

quando hai scaricato il package prog?
ultimamente è stato aggiornato, magari risolve il problema..

oppure prova ad aggiornare il jdk..che versione hai?

prova a scaricarti l'ultima versione del jdk ( Java Development Kit )
dal sito della Sun ( java.sun.com ) e installala sul tuo p.c., anche se è una versione superiore a quella della classe che vuoi usare, va bene uguale, tanto c'è retrocompatibilità.

Ciao.

La soluzione sta nel buttare prog e fare I/O secondo Java standard ;)

Non ci siamo....
Ho fatto un programmino del genere:

code:

import prog.io.*;

class MediaVoti {
  static public void main(String[] args) {
     ConsoleOutputManager video = new ConsoleOutputManager();
     ConsoleInputManager tastiera = new ConsoleInputManager();
     int esame, totale=0, i=0;
     do {
      i=i++;
      do {
        video.print("Immetti voto "+i+": ");
        esame = tastiera.readInt();
      } while (((esame<18) || (esame>30)) && (esame != 9999));
      if (esame != 9999) totale = totale + esame;
      } while(esame != 9999);
      video.println("La media è: "+totale/(i-1));
}
}


Che sul pc dell' uni gira perfettamente, mentre qui sul mio settato con jdk 5.0 su Jcreator me lo compila, ma poi mi dice che la media tra 20 e 20 è -40....

Allora c'è qualcosa che non va.. pesantemente... :shock:
