The modern Java switch is underrated. I always use it in this new way because: The new switch is no longer just an alternative to if-else, but an expression that is cleaner, safer and more convenient for mapping values in modern code. Modern switch is: 1. Fewer errors No more forgotten breaks → no accidental fall-through. 2. Can be written as an expression Assign the result directly: 3. Support for multiple values case ‘OK’, “SUCCESS” -> ‘Success’; 4. Can use blocks with 'yield' Use `yield` when you need to add any logic to a `case` statement other than returning a result, such as logging, additional calculations or conditions switch is not just a statement, but an expression — and this significantly changes its capabilities. #Java #Backend #Developer #JavaDevelompent #Software #Programming
The fact is that all switches are underrated and unpopular.
Good point! Also, as I can see, we can finally make the result 'final'
moreover, the main advantage of the switch expression is exhaustiveness at compile time - all possible cases should be handled. It is useful when matching against sealed class hierarchies
Totally agree - modern switch isn’t just syntactic sugar, it actually changes how you think about control flow. Writing it as an expression makes the intent so much clearer, especially for mapping logic, and removing fall-through eliminates a whole class of subtle bugs. Feels like one of those features that quietly makes everyday code a lot more robust.
Very nice!
It was already possible to do this before by putting the switch statement inside another method and having all cases return values.
