Answer 1

On sololearn you can only one scanner.
Scanner scan = new Scanner(System.in);
kod = scan.nextInt ();
... = scan.nextLine ();

What do you mean with "another time"? It is not easy to read your code because of your polish (hope I'm right) variable names.

Answer 2

Piotr Szkudlarek Normally your ide will cut the connection of your scanner from the device if you end the program. But it is better to close the scanner at the end of your program:
scan.close ();

Answer 4

If you write plecc = "Kobieta" it works. So it has to do with scan.nextLine ();
I need to think about it. Maybe there is a whitespace at the end of your string.

Answer 5

You can also remove all spaces. I changed it in my code:

ps: Your solution to use next () is more elegant. ;)

pps: The white space was at the beginning of the string. But I don't know why.
