Question 211

Given:

and the code fragment:

Which two lines cause compilation errors? (Choose two.)

    Correct Answer: A, E

    Lines 6 and 7 cause compilation errors. The 'var' keyword in Java is used to infer the type of a local variable at compile time. However, 'var' cannot be used for member variables (fields) in a class, method parameters, or return types. In the code fragment provided, 'var' is incorrectly used for the field 'employee' in line 6 and as a method return type in line 7, both of which are not allowed.
