Which is true about the code?

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. Each time the else statement is executed, the variable is redeclared and goes out of scope. Therefore, it is not re-assigned. Similarly, length is effectively final. There are no compile errors, and option E is correct.
