@nyeongAn Nyeong (安寧) Yes, functionally they're similar—both enforce error handling at compile time! The key difference is that Java automatically propagates exceptions once declared, while Rust requires explicit ? for each call. Swift adding typed throws is fascinating validation of the concept.

My blog post explores these differences in depth.

The semantics matter though—Java's approach integrates better with imperative code, while Result<T, E> types fit functional paradigms. Each has its place!
