hallo, ich möchte, dass sich mein programm nach benutzung des filechoosers(public void open), den pfad merkt und ihn an anderer stelle im programm wieder wiederverwendet (public void compile) um ein anderes programm zu starten, leider bekomme ich immer die fehlermeldung, dass das system die angegebene datei nicht finden kann. deswegen denke ich, dass der pfad nict übergeben wird. kann mir jemand helfen?wäre echt lieb
