Hello, I would like some help with ending a program. I am working on some homework for writing code and everything I try will not allow me to end the program. I keep getting a syntax error "expected "}"" and I can not figure it out. I have checked for the brackets and they are both there, if I remove them it still says the same thing. Could some one please advise? Here is the end portion of my code:
{
System.exit(0);
}
}
}
} //end program
Thank you!
We would need more than the end portion. The problem is, you have an open { without a closing }. Double check all your braces and make sure that for every { there is a corresponding } .
Sorry, I am new at this and quite frankly, Java programming is not my bailiwick. Here is the program I have written and have been working on for several weeks for my IT class. Any help would be appreciated, several portions are not working, but right now the ending is frustrating me more as there is no information on how to do this. Thank you!

Well, if you don't start your while loop within a comment, it will probably exit as you expect.
boolean stop = false; //controls if loop below executed [B]while (!stop)[/B]
{I'm sorry, but, if you're not even willing to try, why should I. I gave you what you need to fix yourproblem, regardless of whether or not "Java is your bailiwick". And, if you're opening and closing braces in comments, it's not surprising it doesn't work.

Not willing to try? I am trying and have been for almost 9 weeks! You asked me for more than just the end and that is what I included. You seem to forget that not everyone is a programmer and that some of us are TRYING to learn, we won't get it immediately. I have checked every brace and can not find where you refer. You should be a little nicer when commenting instead of demeaning someone who is attempting to learn.
if you are trying to exit the program if a condition is met if
stop == false
boolean stop = false; //controls if loop below executed while (!stop)
have you try an if statement to check for that condition that will make the program abort
while ( ...... )
{
if(condition to abort)
break;
else
code of the program
}
at least that is what i usually do to abort a program or if you want to check for that condition as soon as the program starts just put the while loop in the else
I have checked every brace and can not find where you refer. You should be a little nicer when commenting instead of demeaning someone who is attempting to learn.
I doubt this, since every { must have a matching } . In your program this ain't true. So quit moaning and fix it honey.

Not willing to try? I am trying and have been for almost 9 weeks! You asked me for more than just the end and that is what I included.

Why the hell should I try to sugarcoat what I tell you? And why the hell should I do your work for you? I not only told you that we would need the rest of the code, I also told you what the error meant, and how to fix it. Considering that, it was expected that you do that before posting the code, then only posting the code if there was still a problem (probably a different one), and you didn't, that is showing no effort. Checking the braces is easy. Simply count up for each opening and down for each closing, and you should end at 0. Then, if that's the case, and it still doesn't work, then start looking closer to ensure that none of the blocks "overlap". How is that so hard? And why should anyone have to it for you? And as far as showing no effort? Posting your code and saying do it for me, is showing no effort. And complaining when someone makes a suggestion (regardless of the language used), because they haven't done it for you, is showing no effort. That shows that you simply want someone to do it for you, not "help" in completing it. "Help" is when someone tells you what you're doing wrong, and how to fix it. If they then, do the fix for you, it is no longer "helping", but "cheating", whether it concerns homework, work, or hobby, doesn't matter.
Well, matching braces or no, unless the while loop statement is moved from the end of the comment on the boolean "stop", you won't even have a loop. Statements in comments don't execute so well :P
