Description
If a method wants to throw an exception, it must specify this behavior.

}
exception-list is a comma-separated list of the exceptions that a method can throw.

static void throwOne() throws IllegalAccessException {
System.out.println("Inside throwOne.");
throw new IllegalAccessException("demo");
}//from w ww .jav a 2 s . co m
