What is an example of Apex?

Could you please provide an illustrative example of Apex? I understand it's a high-level, statically typed, object-oriented programming language designed specifically for the needs of blockchain developers, but I'm curious to know how it's being utilized in practice. Is there a specific project or application that showcases the capabilities of Apex in an effective manner? I'm eager to learn more about its real-world applications and the advantages it offers over other programming languages in the cryptocurrency and finance space.
