Answer 1

You can do it the same way but by adding the length of your parameter :

(the syntax could not be good as I don't know flex)

image_path.substring(image_path.lastIndexOf("/img") + "/img".length);

But you sould use the following regex to get the number :

.*/demo/img([0-9]+)\.jpg

then use capturing group to get the number ;)

Answer 2

image_path.substring(image_path.lastIndexOf("/img")+4, image_path.length-4);
