Can someone tell me why the result i get in GUI is not the same with the result in command prompt??:(

the result in cmd is correct but the result in GUI is wrong...

Something is wrong with your code.

We don't have your code so we can't say exactly what is wrong with it.

something "very" critical is missing from your question.

try psting the code

here's are part of the coding...

actually, i use the same method for the other option. It works...but i don't know why the output in cmd n output in GUI are different in this option

[r035198x]

You should have formatted the code and posted it wrapped with code tags to make it more redable.
What exact difference are you getting? You are obviously not sending the same string to your GUI that you are sending to your console somewhere. You have lots of sysouts in your code so you need to say which one you are not getting to your GUI.
