🕵️‍♂️☕ GUESS THE JAVA VERSION: CAN YOU SPOT IT?

🔸 TLDR

▪️ If you see var in Java local variables → think Java 10+ ☕🧠

🔸 THE QUIZ (GUESS BEFORE READING THE ANSWER)

🔸 OPTIONS

▪️ Java 1

▪️ Java 2

▪️ Java 10

▪️ Java 13

▪️ Java 16

🔸 ANSWER

✅ Java 10

🔸 WHY? (VERY SHORT)

▪️ The giveaway is var: local-variable type inference was introduced in Java 10 (JEP 286).

▪️ You can use var for local variables, for-loop indexes, enhanced for, and try-with-resources variables (as shown here).

🔸 TAKEAWAYS

▪️ var reduces boilerplate while keeping Java statically typed ✅

▪️ Works only for local variables (not fields / params)

▪️ Requires an initializer (no initializer = nothing to infer)

▪️ The inferred type is a real compile-time type, not “dynamic typing”
