JAVA GUI Entfernungskonverter konvertiert nicht mit Radiobuttons

Question

Wenn Sie die Datei ausführen, wird es funktionieren, bis Sie eine Zahl in das Textfeld eingeben, und dann bricht es und sagt leere Zeichenfolge. Ich brauche nur Hilfe mit diesem Teil. Ich benutze 1 Zoll im Zollfeld, um in Zentimeter umzuwandeln. Ich habe den Rest auskommentiert, nur um Zentimeter zu testen und zu konzentrieren. ohne die Kommentare stürzt es immer noch auf die gleiche Weise ab. Das Problem scheint aus dem Bereich der Linie 529 zu stammen, der der Aktionshörer ist. alle und alle Hilfe wäre wunderbar und geschätzt

Answer 1

Wenn Sie Ihren Bildschirm erstellen, verwenden Sie 1 Variable für TextField. Sie verwenden es, um ein neues TextField zu erstellen und dieses dann zu Panel 1 hinzuzufügen. Dann verwenden Sie es, um ein neues TextField zu erstellen (den Verweis auf den letzten zu verlieren). Dies wiederholt sich, bis Sie zum letzten kommen. Das bedeutet, wenn Sie Ihren "Eingabe" -Wert vom "textField" -Objekt erhalten, wird nur der letzte Wert angezeigt, den Sie gemacht haben (der letzte auf dem Bildschirm). Sie müssen separate Variablen erstellen, eine für jedes TextField. textInches, textFeet, textYards, etc.

UPDATE: Hier ist ein Code, der Ihnen helfen könnte, Sie zu glätten.
