java - Passing an array from class A to class B

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

To pass data between activities

//to pass array use
intent.putExtra("intarray", manualpointx);
// to pass list of point use
intent.putParcelableArrayListExtra("bundle", (ArrayList<? extends Parcelable>) manualpoint);

For classes

create public getter methods to return the values and call those methods from any class where you want to get the values
