If doubt

Read from JLS the following quote...
--------------------------------------------------
14.7 Statements are thus gramatically divided into 2 categories: that which might end in an if statement that has no else block(short if statement) and those that definitely do not.Only those that definitely do not end in a short if statement may appear as an immeadiate substatement
before the keyword else in an if statement that does not have an else clause
-------------------------------------------------

Am confused about this
Can someone help please
Thanks

I'm confused because I can't find this in the JLS. 14.7 deals with labeled statements. Do you have a link so I can see this in context?

I found it... it's actually 14.5.

if (door.isOpen())
if (resident.isVisible())
resident.greet("Hello!");
else door.bell.ring();// A "dangling else"

"Only statements that definitely do not end in a short if statement may appear as an immediate substatement before the keyword else in an if statement that does have an else clause."
We see in the above example a violation of the statement above. The sub-if is trying to be a short-if but it can't because the the main-if's else statement gets assigned to the short if. In other words the above code gets turned into:

if (door.isOpen())
if (resident.isVisible())
resident.greet("Hello!");
         else door.bell.ring();

The solution around this problem is the proper use of braces to identify where the if-else statements belong.

if (door.isOpen()) {
if (resident.isVisible()) {
resident.greet("Hello!");
        }
}
else 
    door.bell.ring();

I am sorry.. it is under 14.5 in the chapter "Blocks and Statements" under the heading "Statements" in the last before paragraph...
Thanks.
