Hi,
ich bin im Moment an einem größerem Projekt, ich bekomme hier eine Exception von der ich nicht ganz verstehe wo sie herkommt:
Hier die Methode in dem der Fehler auftritt:
Hier werden diverse ArrayLists initialisiert:
Falls jemand eine Idee hat ,
ich bin für jede Info dankbar.

ich bin im Moment an einem größerem Projekt, ich bekomme hier eine Exception von der ich nicht ganz verstehe wo sie herkommt:
Code:

Hier die Methode in dem der Fehler auftritt:
Java:
btn1.addActionListener(new ActionListener() { //ASK-Darstellung
@Override
public void actionPerformed(ActionEvent e) {
ImageIcon askOne=new ImageIcon(getClass().getResource("/Transmit/ASK/one.png"));
ImageIcon askZero=new ImageIcon(getClass().getResource("/Transmit/ASK/zero.png"));
int x=0;
for(int i:bitVal){
if(i==0){
lblList.get(x).setIcon(askZero);
x++;
}else{
lblList.get(x).setIcon(askOne);
x++;
}
}
}
});
Hier werden diverse ArrayLists initialisiert:
Java:
.....
static JLabel lblVal1,lblVal2,lblVal3,lblVal4,lblVal5,lblVal6,lblVal7,lblVal8,lbl1,lbl2,lbl3,lbl4,lbl5,lbl6,lbl7,lbl8;
ArrayList<JLabel> lblList=new ArrayList<JLabel>(Arrays.asList(lbl1,lbl2,lbl3,lbl4,lbl5,lbl6,lbl7,lbl8));
.....
public ArrayList<Integer> bitVal=new ArrayList<Integer>();
.....
txtVal.setText("00000000");
for(char c:txtVal.getText().toCharArray()){ //bitVal wird vorgefüllt
bitVal.add((int)c);
}
......
ich bin für jede Info dankbar.
