I am quite new and seem to be getting the same problem, which is "unexpected token: )"
I want to read from a text file the amount of lines, then return a string if there are more than a certain number of lines and return a different string if there are less then that number of lines.
The code I am using is:

String lines[] = loadStrings("test.txt");
int i = lines.length;
for (i >= 3;) {
 println("More than 3");
}
for (i < 3;) {  
   println("Less than 3");  
}

No luck, now get the following error:
"Syntax error, maybe a missing right parenthesis?"

another tip: try using else instead of another if statement:

Code:

if (i >= 3) {
//do something
}
else {
//do something else
}
 

this code is easier to understand and easier to manage if the conditional changes. you would only have to change it in one place.
