Have you ever wondered why `Optional.orElse()` sometimes executes code even when the value is already present?
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.
Code examples included with clear console output demonstration.
