Can someone Please help me find whats wrong with this? Its Higlighted in red and the erroe mssg when i try to copile is
55: ')' expected
can someone help me fix it?


so what should i do? im new to this so how would i put in to fix is?


A literal String, such as that, has a quote at the front and at the end. I assume that the entire contents betweens the parens should be a literal String, right? So why is the second quote (which ends the String literal) in the middle of it?


Hi, this is sugarskull
and you just responded to my problem and you put that i needed to check the quotes but what should i put them on and why does my error on clem say ')' expected?
System.out.println("firstVar is 13" or greater. \n);
if you can please help me i will appreciate it!!!
Thanks Sugarskull

I gave you another hint. Have you even tried to change anything yet? I am not going to give you the answer. I will give a third hint, and say that, in that statement, as soon as the String literal ends, the compiler expects the closing paren. Where, in that statement, does your String literal end, and where is your closing paren? Where should the String literal end?


No, really?

And do you actually want an "n" after the period, or did you mean "\n" for a newline (which is also redundant since println adds a newline anyway)?

Aside from the fact that it is counter productive to simply spew out the answer (the student learns nothing that way), the question has already been answered (here also if the OP was willing to use that thing between its ears) in a cross-posted thread, since the OP wasn't willing to use it.
