I’m pretty sure by GUI they mean a WYSIWYG type thing where you drag and drop things into a GUI (meaning user interface) and then you have code. So again WYSIWYG.

Since they mentioned Swing and also there’s a link to the GUI code.

I like GUI code. Meaning I like that they exist. But, also yes, they can get messy.

Such cool stories. You guys rock… Or are lying lol. I was once working in electronics job. I was running a circuit under test for which we had access to the source code for it. I was amazed by how source code turned into action. Once they out-source my job, I went to get CS degree. And… Now I work what is basically T1 IT

I enjoyed it way too much on my emulator with infinite life.

For your case, you are going to need at least 16GB. I remember that 4 years ago I loaded Android studio with 8GB and it took a while to load. It also ran a little slow. I suggest 16GB,preferably 32GB and SSD at least 512.
