Question

I have an array named Floors in class A, it contains values something like the following:

  List<Point> manualpoint = new ArrayList<Point>();
  int[] manualpointx = {135,200,300,155,235,300};

Let’s say I wish to pass these values to class B, supposingly class B has already declared a superclass View

public class DrawView extends View implements OnTouchListener { 
    @Override
    public void onDraw(Canvas canvas) {
        //pass the values into this class
    }

}

How do i pass the values from class A to B?

Answer 1

You can do something like this.

final class A
{
     private static int[] manualpointx = {135,200,300,155,235,300};
     private static List<Point> manualpoint = new ArrayList<Point>();

     public static int[] returnArray()
     {
          return(manualpointx);   
     }

     public static List<Point> returnList()         
     {
          return(manualpoint);
     }

}
public class DrawView extends View implements OnTouchListener
{ 
    @Override
    public void onDraw(Canvas canvas) 
    {
         //pass the values into this class
         int arr[]=A.returnArray();
         List<Point> list=A.returnList();
    }
}

If you need only non-static fields in your class A and if you just want to use non-static methods, you will have to access them via an instance of the class A from your class DrawView.
