What is the difference between Optional and null in Java?
In Java, Optional is a container that may or may not hold a value, while null represents the absence of a value.
Why should I use Optional instead of null?
Using Optional helps avoid NullPointerExceptions and makes your code more expressive and easier to understand.
Can you give me an example of using Optional?
Sure! You can create an Optional like this: Optional<String> name = Optional.ofNullable(getName()); This way, you can safely check if a value is present.
Are there any performance concerns with using Optional?
Yes, while Optional provides safety, it can introduce overhead. It's best used for return types rather than fields.
