单选题What is wrong with the following code?() class MyException extends Exception {} public class Qb4ab { public void foo() { try { bar(); } finally { baz(); } catch (MyException e) {} } public void bar() throws MyException { throw new MyException(); } public void baz() throws RuntimeException { throw new RuntimeException(); } }A
Since the method foo() does not catch the exception generated by the method baz(), it must declare the RuntimeException in its throws clause.B
A try block cannot be followed by both a catch and a finally block.C
An empty catch block is not allowed.D
A catch block cannot follow a finally block.E
A finally block must always follow one or more catch blocks.
