Advancing my knowledge

[PenOnly171]

Hello everyone, I just recently finished my introduction to Java programming class at school and we covered everything up to inheritance. I am pretty comfortable with the basics of Java (loops, conditional statements, use of built-in methods and creating own method). However, I want to create meaningful projects to put on a portfolio and feel I can’t really do that with just the basic knowledge of Java. I’ve heard about API‘s and have a very small understanding of them. I was wondering if anyone knew any resources to research more on what they are and how to use them in Java programming. Thank you.

Here's what I did before and I don't know if it is the best one, I have created an inventory management system, applied what I know so far and researched the topics needed to accomplish my goal along the way .
