Hi in the below code i have one string variable.I want to convert that string into integer of arrays.

Am just trying with my code but it is not working .Am getting an issue

Number Format exception:"["

    String cct =  "["+ cct1 + " " + cct2 + " " + cct3 + " " + cct4 + " " + cct5 + " " + cct6 + " " + cct7 + " " + cct8 + " " + cct9 + " " + cct10 + " " + cct11 + " " + cct12 + "]";
    String intensity =  "["+ intensity1 + " " + intensity2 + " " + intensity3 + " " + intensity4 + " " + intensity5 + " " + intensity6 + " " + intensity7 + " " + intensity8 + " " + intensity9 + " " + intensity10 + " " + intensity11 + " " + intensity12 + "]";

    number =new int[cct.length()];
    try{
        for(int i=0;i<cct.length();i++){
            number[i] = Integer.parseInt(String.valueOf(cct.charAt(i)));
        }
    }catch(NumberFormatException ex){ // handle your exception
      ex.printStackTrace();
    }
    cctvalues =new int[intensity.length()];
    try{
        for(int i=0;i<intensity.length();i++){
            cctvalues[i]=Integer.parseInt(String.valueOf(intensity.charAt(i)));
    } catch (...) {

    }
