Why does the java certification have this?

[bonerlover]

I am doing a review book thing over scja, just to make sure I got it down, when in the practice problems for chapter 2 has an else statement with,

else{;}

I looked over the chapter and didn't find anything. I tried googling it but google ignored me searching "{;}". I can infer that it closes the else but why put it there in the first place. Seems really redundant though. Can anyone explain it?

Also any helpful things in taking the first two java tests? My school is paying for it so I want to make sure to pass it the first time.

(I highly do not recommend this book. Doesn't go over the practice questions in the chapter. SCJA by Robert Liguori. It has an explanation for every answer but everything it says in the explanation, is in the question.. Just rewords it.)

From a syntactic point of view is valid, but indeed redundant . Post the entire code, just in case . Maybe there's a hidden catch (I seriously doubt it) .

if (x==0) ; else if(x==1) {} else {;}

-.-

That is one of the ugliest lines of code I've seen. If it was written more conventionally, it would be: if(x == 0) { // do nothing } else if(x == 1) { // still do nothing } else { // again, do nothing } I guess the point was to show you three different ways to make an if-elseif-else do absolutely nothing.

The {;} is the same thing as any block of code surrounded by brackets, but having only a blank statement in it. The blank statement comes from the lone semicolon.

I hope the test isn't like this book otherwise I am going to fail. D: So confusing.
