Und hier ist der code:

    PiePanel pieChart;

    public ShowPieChart(ArrayList<Float> val, ArrayList<Color> col) {
        super("Pie Chart");
        int index = 1;
        setDefaultCloseOperation(JFrame.HIDE_ON_CLOSE);
        FlowLayout flow = new FlowLayout();
        pieChart = new PiePanel(val.size());
        for(Iterator<Float> i = val.iterator(); i.hasNext(); )  {
         pieChart.addSlice(col.get(index), val.get(index));
         index++;
        }
        setLayout(flow);
        add(pieChart);
        setVisible(true);
    }
}

Ich versuchte viele Dinge, um dieses problem zu beheben, aber ich kann nicht sagen, warum ich noch immer eine IndexOutOfBoundsException. Zu den besten meines Wissens, ich bin mir ziemlich sicher, dass diese korrekt ist! Können Sie mir helfen?

Sie versucht, die Einstellung der index 0 statt 1?
+1 Auch angegeben werden, in Frage. 🙂
