Looping through Drawable resources?

I want to loop through ten Drawable resources named ab1, ab2 ab3,ab4,ab5 etc. and call a function on them. 

  b = decodeSampledBitmapFromResource(getResources(), R.drawable.ab1, reqHeight, reqWidth);

i am looking for something like this. 

 for(int i =1; i<11; i++)
 {
     b = decodeSampledBitmapFromResource(getResources(), R.drawable.ab[j], reqHeight, reqWidth);
  }

How would I do that?

I am not well experienced in android but in Java SE I put every object in a java.util.Vector and iterate over the vector elements.

Maybe some like this

for(int i =1; i<11; i++) {
b = someMethod(getResources(), vectorDrawables.elementAt(i), reqHeight, reqWidth);
}

I just cant remember how to add a GUI element to a vector.

You can put those objects in list

list.add(R.drawable.ab1);
list.add(R.drawable.ab2);
list.add(R.drawable.ab3);
list.add(R.drawable.ab4);
.
.
.

and then you can iterate through that list, using list.get(i) and pass each object in the method.

for(int i =1; i<11; i++)
 {
     b = decodeSampledBitmapFromResource(getResources(),list.get(i), reqHeight, reqWidth);
  }
