In this video, I explain the real difference between `orElse()` and `orElseGet()` in Java Optional with a live code demo. Topics covered: • How `orElse()` works internally • Why unnecessary method calls happen • Lazy evaluation with `orElseGet()` • Performance implications • Best practices for real-world Java applications • When to use `orElse()` vs `orElseGet()` If you're preparing for Java interviews, improving backend performance, or learning clean Java coding practices, this video will help you avoid a very common mistake.
