CheckboxField

I have two classes named Screen1  and   Screen2.

in Screen 2 there is a CheckBoxField.

String[] choices = {"AB","CD","EF","GH"};

 

for(int i=0; i<choices.length;i++){  

     if(checkBox[i].getChecked()) {

              c1[k]=checkBox[i].getLabel();

           k++;

}}

by the above code i can able to put the selected fields in a String of array c1.


But i want to access that c1(string array) in anther class i.e Screeen1.

Both the classes are public.

But my program throws NULL POINTER EXCEPTION.

Please any one reply.

Thank you.

Re: CheckboxField

Hi,
pass that string array to another class
UiApplication.getUiApplication().pushScreen(new nextclass(c1));

class nextclass extends MainScreen{
private String[] StrArray;
nextclass(String[] array){
this.StrArray= new String[array.length];
//do what ever you want
}
}

Thanks & Regards

Re: CheckboxField

Sorry Sir,

  Both the classes extends MainScreen.

In both the Classes I have default constructors only. Then how can i call 

UiApplication.getUiApplication().pushScreen(new nextclass(c1));
