I get an exception in my code, so it doesnt show more than the first print request, te problem seems to start at line 12 i dont know if i need something else, or is a problem with the int variable type

Exception in thread "main" java.util.InputMismatchException
        at java.base/java.util.Scanner.throwFor(Scanner.java:939)
        at java.base/java.util.Scanner.next(Scanner.java:1594)
        at java.base/java.util.Scanner.nextInt(Scanner.java:2258)
        at java.base/java.util.Scanner.nextInt(Scanner.java:2212)
        at App.main(App.java:12)```

    From the _javadoc_ of class `java.util.InputMismatchException`: _Thrown by a Scanner to indicate that the token retrieved does not match the pattern for the expected type, or that the token is out of range for the expected type._ You are not entering a valid integer when this line of your code executes: `empleados = leer.nextInt();` Are you entering a very big number that is larger than `Integer.MAX_VALUE`? – Abra Nov 19 '21 at 03:39

From what I can tell, it seems like you might be inputting characters instead of numbers.

Specifically at this stacktrace:

-----------------------------------------------------------
     means that it doesn't match a specified pattern
         possibly int>String doesn't work?

sources
InputMismatchException -- https://docs.oracle.com/javase/7/docs/api/java/util/InputMismatchException.html

If you mean by the locale, if you're inputting 1.2 or such, try changing the locale by using .useLocale(Locale.ENGLISH), as it could be interpreting something that's not like 1,2 as a string.

locale -- Why am I getting InputMismatchException?
