Checking numbers on signs?

How do i for example, if the bottom line of the sign is 3, how do i check if it's over 0 or not.
Like:

Code:

if(signText[3] <= 1) {
    //TROLOLOL
}

 

Code:java

 
String lastLine = sign.getText(4); //You will need a sign reference variable to the Sign you are getting
int lastLineNum = Integer.parseInt(lastLine);
if (lastLineNum <= 1) {
//whatever you planned to do
}

 

shouldn't it be >= 1, because you said over 0?

 

Yes, but you should really be catching (and cleanly handling) NumberFormatException from Integer.parseInt() or be prepared for a bunch of ugly backtraces in your server log...

 

what if you simply use "num > 0"? You can almost "talk" to java.^^

 

True, I just typed this up real quick.
