🔸 THE QUESTION

Can you identify the first Java version that supports this code as a standard feature? 👇

Which Java version is it?

▪️ Java 1.4

▪️ Java 7

▪️ Java 14

▪️ Java 16

▪️ Java 21

▪️ Java 25

🔸 TRY BEFORE CHECKING THE ANSWER 🤔

Take a moment before reading further.

This code is using a modern switch style:

▪️ the switch returns a value

▪️ the cases use -〉

▪️ there is no fall-through like in the old switch form

Do you have your answer? 👀

🔸 TLDR

If a switch returns a value directly and uses case -〉, think Java 14 ☕

🔸 THE ANSWER

✅ The correct answer is: Java 14

This code uses a switch expression.

That means the switch does not only execute code: it also produces a value that can be returned directly. The case -〉syntax is part of that feature, and switch expressions became a standard Java feature in Java 14 with JEP 361.

A related detail: yield is only needed when a case uses a block and must explicitly return a value from that block. In your example, each case already returns a simple value, so yield is not necessary.

🔸 WHY THIS MATTERS

This is a good example of how Java became more expressive over time.

With switch expressions, code is:

▪️ shorter

▪️ clearer

▪️ safer against accidental fall-through

▪️ closer to an expression-oriented style

That is why this feature is easy to recognize once you know what to look for.

🔸 TAKEAWAYS

▪️ switch expressions became standard in Java 14

▪️ case -〉 is a strong visual clue

▪️ yield is used only for block-style cases

▪️ This feature helps write cleaner and safer Java code
