JDoodle: Code Compiler

It’s a Good Compiler. It’s what i always use when coding but there’s a tiny problem which bearable but pls fix it if possible. Sometimes when i have an error in my last coding and then i fixed it already, when i try to run the program, it still says error but it gets fixed if you try it again. But pls tho if possible fix it.. there’s one time that i have to do it again cz i redo it all over just because of a bug that says it’s an error which is not..
