Practical applications Java course

Question

So, I’ve learned a good chunk of Python a while ago and I could make some useful scripts. I know Java isn’t a scripting language, but I’ve learned the entire Java course except for the last module (I’ll finish that one tomorrow or the day after) and yet I can’t recreate my python codes that are just made of basic functions. Like there are so many things missing that I could do with python, but not in java... like the modules haven’t even explained how to retrieve an index from a value, which to me is essential, what am I missing here?

Answer 1

modules are for bigger projects, as java begginer you don't need to use it, perhaps you mean API

for second problem try example to explain it
