What is the result?

A. 5 7

B. 5 8

C. 8 7

D. 8 8

E. Compilation fails

F. An exception is thrown at runtime

Answer :

E is correct. The parameter declared on line 9 is valid (although ugly), but the variable name ouch cannot be declared again on line 11 in the same scope as the declaration on line 9. A, B, C, D, and F are incorrect based on the above. (OCA Objectives 1.1, 2.1, and 2.5)
