Instead of using
imageIndex+=1;
if (imageIndex == imageResIds.length) {
imageIndex = 0;
}
On could type:
imageIndex = (imageIndex+1) % imageResIds.length;
Saves time and ensures the index will return to zero whenever it reaches the maximum length/size. I find it easier too, whenever I need to make changes to whether the increment must occur before or after updating the status of an object.
It's definitely not a big difference, I just learned this in one of my classes, where we worked with RingBuffer
