Hi all!!
i have a 2 classes class(in Java) First and class Second. There is e method in classSecond
public void update(String reading,String writing) {
ArrayList1.add(reading); System.out.println("reading: "+reading);
ArrayList2.add(writing); System.out.println("writing: "+writing);
}
And this update() method is called from class First like the following ;
object_ofClassSecond.update(reading,writing);
and classFirst obtains these reading, writing parameters from a third class(lets call it class Third) like the following:
String reading=request.getParameter("reading"); String writing=request.getParameter("writing");
There are some other things but i dont want to go into details.So the problem is whenever there is a reading or writing i get them from classThird and then pass them from classFirst to classSecond via the update() method.However sometimes this getParameter() method does not return anything and i need to assign the null values to my reading and writing variables in these kind of situations.I want to see the null values in the ArrayList1-2 in class Second whenever getParameter() method does not return anything.Could you please help me to do this? Thanks a lot in advance!!!
