public class ThrowsDemo {
static void throwMethod() throws Exception {
System.out.println("Inside throwMethod.");
throw new IllegalAccessException("demo");
}
public static void main(String args[]) {
try {
throwMethod();
} catch (IllegalAccessException e) {
System.out.println("Caught " + e);
}
}
}

A) Compilation error
B) Runtime error
C) Compile successfully, nothing is printed.
D) inside throwMethod. followed by caught: java.lang.IllegalAccessException: demo
Answer is: A
But in JLS�11.2 it says:
For each checked exception which is a possible result, the throws clause for the method (�8.4.4) or constructor (�8.8.4) must mention the class of that exception or one of the superclasses of the class of that exception.
Isn't Exception a superclass of IllegalAccessException

OK, I found that the catch clause must declare
that it catches objects of type Exception because of the declaration of throwMethod. The problem was NOT in the throwMethod...
