"Do you know how to use the compiler?"  -> Yes, I do know.
"So add a field "figure" and a field "type" to your class that will hold that information about a playing card, and assign them from the constructor parameters." -> I hope it's okay how I did it.

I tested my solution and it worked. Thank you very much for your hints. It helped me a lot!

I'm thinking to continue like this or should I use a boolean method?
It's not clear how i use those parametres of contructor. I will look in documentation and I will return with a better code

I did like this till now, but I'm trying to figure out how to continue. I suppose it's a much efficient solution

I need to write the implementation of a GameCard class that stores the information corresponding to a card. The class must have 2 private fields: a String that saves the figure (7, 8, 9, 10, J, Q, K or A) and a String that saves the type of playing card (RED HEART, BLACK HEART, CLOVER or CARO) . The class will have a constructor that receives a String and a String as parameters and throws a GameException exception, also defined by you, if one of the parameters is not part of the variants listed above.

The thrown exception message must be Invalid Figure if the first parameter is invalid, Invalid Type if the second parameter is invalid, or Invalid Figure and Type if none of the above parameters follow the rules.

This is what I tried, but i dont know how to continue:

   Copy Code
   private List<String> figure = Arrays.asList("7", "8", "9", "10", "J", "Q", "K", "A")

   Copy Code
   private List<String> type = Arrays.asList("RED HEART", "BLACK HEART", "CLOVER", "CARO")

I was thinking of creating a method that should return the number of valid dates. How can I use SimpleDateFormat?

class ValidatorDate {
public static int ValidDates(String[] words) {
   DateFormat format = new SimpleDateFormat("dd/MM/yyyy");

public class Main {
public static void main(String[] args) {
   System.out.println(ValidatorDate.ValidDates(new String[]{"car","bench","01/04/2019",  "01/13/2019", "29/02/200s"}));
   // answer: 2(01/04/2019 and 29/02/200s are valid dates)

"Is it a requirement that you use regular expressions?" - Yes
"Why are you printing the number of words minus 1?" - my mistake, I fix it.
"Presumably because otherwise your output doesn't match the expected output for the given input data."- Exactly. I receive a wrong answer at the last test when I'm submitting my solution on the platform where I'm learning.

Input data
You will read the text of the email from the keyboard. It can span multiple lines and contains only lowercase letters of the English alphabet and spaces.

Output data
A single integer will be displayed, representing the number of distinct words in the email

The text does not contain more than 100,000 words, and each word can contain up to 25 characters.

Input data:
