Dear Community,

i'm new here and i'm in a phase where i like to create a productive environment for me. This includes the real world and then virtuel.

There are many topics i look into. One of them which got me pretty curious is java, so i see it as a nice start (motivation & goals).

Sadly i found no tutorials about this. If there is something in this area, please post me the links.
The tools i need are already installed. But i don't know how to start; well i started with some thoughts:

For this site i need to write a code which finds just pictures with a special name

Exp:
Decrypting Link: "https: //test123.org/blub/Photos/"
--See Linked Photos--
--Go To Photopage--
"https: //test123.org/blub/Photo/"
--On This Site, search and download "https: //files.test123.org/blub/*-720.jpg"--

I think its pretty simple. Okay i need the right syntax but i think u get what i want to accomplish.

Where do i Start? How many files do i need and where to save them?
Are there Plugins which are working similar? And how can i find them to see how it should work?

I hope u can give me some information that I can get into it. If u need more informationen from me, don't hesitate to ask.

Thanks You
