Creating a next and previous Tutorial

Hello Uniters !

So, basically i want to create a tutorial (GUI) that shows some image of tutorial… and i could press next and previous…

it’s like book tutorial, but the different is, there is no book flipping animation… its just like if i press next, the image change to the next tutorial image…

i’ve been lurking around and couldn’t find any of good tutorial, all are about book flipping…

so, could someone help me with basic algorithm for this?

put your images in an array list, then make your gui saying next and previous in and make it cycle between the array
