Here is the code,

Card.java

public class Card {
    private int number;

    public Card(int number){
        this.number = number;
    }

    public int getNumber() {
        return number;
    }

    public void setNumber(int number) {
        this.number = number;
    }

    @Override
    public String toString() {
        return "Card{" +
                "number=" + number +
                '}';
    }
}

CardPlay.java

import java.util.*;

public class CardPlay {
    // I have assumed card with values that is : (1-10), Jack - 11, Queen - 12, Kind - 13, Ace - 14;
    private List<Card> cards;

    public CardPlay(){
        cards = new ArrayList<>();;
    }

    private void hand(Card[] mCards){
        cards.addAll(Arrays.asList(mCards));
    }

    private boolean issorted(){
        for(int i=1; i<cards.size(); i++){
            if(cards.get(i).getNumber() < cards.get(i-1).getNumber()) return false;
        }
        return true;
    }

    public static void main(String[] args) {
        Card[] mCards = new Card[14];
        mCards[0] = new Card(12);
        mCards[1] = new Card(1);
        mCards[2] = new Card(9);
        mCards[3] = new Card(8);
        mCards[4] = new Card(2);
        mCards[5] = new Card(14);
        mCards[6] = new Card(5);
        mCards[7] = new Card(7);
        mCards[8] = new Card(13);
        mCards[9] = new Card(3);
        mCards[10] = new Card(6);
        mCards[11] = new Card(4);
        mCards[12] = new Card(10);
        mCards[13] = new Card(11);

        CardPlay cardPlay = new CardPlay();
        cardPlay.hand(mCards);

        System.out.println("isSorted? : "+cardPlay.issorted());
    }
}
