Hello, I started to develop in java with the IntelliJ IDEA Community software but I have a problem when I finish my code and it does not display any error (a friend of mine has the same problem) when I launch it it shows me this error,
I have search on many forums but none market or none display the answer, I hope you can help me and quickly because it is extremely important as a project (sorry if I was wrong in the location of my topic I was not sure what it was)
thank you
