1z0-819 Exam - Question 101

In Java, the exception M is a subclass of L and thus can be caught by a catch block that handles exceptions of type L. Therefore, adding catch(L e) is sufficient to catch both M and L exceptions, making the code compile successfully. Catching L will automatically catch both M and L exceptions because M extends L. Other options like catching multiple exceptions with a multi-catch block are unnecessary and may result in compilation errors if subclasses are included inappropriately.
