I have coded a little program and when I tried to compile it, I got 9 error messages. And also I qam very sorry for the Language. It is german. So if you know German maybe help me. I just started with coding. I hope that I can learn from you talented programmers. Thanks darkwastaken Errors are:

    So you want to guess a number but get errors and now you want *us* to guess the errors? Please provide specific error details, what kind of errors, on what line, etc. – luk2302 Feb 03 '21 at 14:25
  • I edited the Question. Sorry for that I am like I said, very very new to this topic. – darkwastaken Feb 03 '21 at 14:34
  • What about the first one *"class Zahlraten is public, should be declared in a file named Zahlraten.java"* - is it in a file called `Zahlraten.java`? – luk2302 Feb 03 '21 at 14:37
  • no, the files name is Zahlraten.java – darkwastaken Feb 03 '21 at 14:38
  • Okay, `versuchszaehler` != `versuchzaehler`, `randoGenerator` != `randomGenerator`, `var` does not exist, what java version are you targeting, obviously not the right one since the compilter does not understand `var` yet. `JOptionPane.showMessageDialog(...)` does not work for only a `String` argument, etc. All these errors are pretty clear, you simply need to work through them. – luk2302 Feb 03 '21 at 14:47
  • That was very helpful, Thank you and have a nice Day/Night! – darkwastaken Feb 03 '21 at 14:51
  • I updated both Java and the Compiler. Now everything works with your help. Thank you to all of you. – darkwastaken Feb 03 '21 at 14:58
