This statement is supposed to evaluate the boolean, and based on it's value return the result of the statement to the left or the right of the colon. In other words, the two statements are required to return a value. Since println() is void, I believe this syntax will throw error. So you are right, in your example, the if statement is definitely the correct approach. To put it more simply, the question mark statement must evaluate to (or return) a value of some sort. It is not supposed to be used to perform an action. I hope that makes sense. :) Well, that is the one way you are not supposed to use the question mark statement.

Well I used something like

(boolean)? System.out.println(”Some text”):System.out.println(”Some other text”);

Putting it in an if statement works no problem.

Remember, you can't use the < and > unless you put them in the <pre> tag. Click the code button above the textbox. Observe: <pre lang="java">inside here I can use <> as normal</pre> Alternatively you can use the &lt; and &gt; HTML entities like I did above. Also, preview button does wonders for you. ;) Patrick - I think your comment got eaten. Remember, you can’t use the < and > unless you put them in the <pre> tag.
