❌ A. The first compiler error is on line A ❌ B. The first compiler error is on line B ❌ C. The first compiler error is on line C ❌ D. The first compiler error is on line D ✅ E. The code compiles successfully
Explanation: Lambdas are only allowed to reference effectively final variables. You can tell the variable j is effectively final because adding a final keyword before it wouldn’t introduce a compile error.
