What are the limitations of using switch-case statements in Java?

Switch-case statements in Java have several limitations, such as: they can only evaluate expressions of certain types (like int, char, String), they don't support ranges, and they can lead to code duplication if not structured properly.

Can you explain why switch-case can't handle ranges?

Sure! Switch-case statements evaluate a single expression against multiple constant values. They don't support conditions like 'between' or 'greater than', which means you can't directly check for ranges.

Are there any alternatives to switch-case for handling multiple conditions?

Yes, alternatives include using if-else statements, or Java 8's lambda expressions and streams for more complex conditions.

What about performance? Is switch-case faster than if-else?

In some cases, switch-case can be faster than if-else, especially when there are many cases, as it can be optimized into a jump table. However, the performance difference is often negligible for a small number of cases.
