Kompajler mi izbacuje ovu greshku.

Mislim da greshim negde sa ovim nizom na liniji 43

Code:
39    private String[] teme(){
     40    String[] temp = null;
     41    UIManager.LookAndFeelInfo[] laf = UIManager.getInstalledLookAndFeels();
     42    for(int i = 0; i < laf.length; i++){
     43        temp[i] = laf[i].getName();
     44
     45    }
        return temp;
    }

Ali ne znam kako to da reshim molim vas ako neko zna reshenje.
Probao sam sa try catch blokovima i onda mi pokrene program ali nishta ne prikazuje sem frejma postavio sam i ceo kod dole.
I poceo sam neki kalkulator da pravim i pojavio mi se isti problem ali cu pokushati sam da ga reshim ako mi neko pokaze kako ovo da rashim.
Unapred hvala
