Array: Can't use > or < ?

[webguy08]

I'm writing a piece of code for a game which I am a creating: just a simple game where the player must guess higher or lower for the next card in the sequence.

I am just 1 step away from it working, however I am very confused as to how I can tackle the problem I am faced with.

Here is the code:

/**
 * This class models a player.
 */
public class Player
{
    private String name;
    private Card[] card = new Card[5];
    private int score = 0;
    
    /**
     * Contructor for objects of class Player.
     * @param A String which initialises the name of the player.
     */
    public Player(String name)
    {
        this.name = name;
    }
    
    /**
     * Gets the score of the player.
     * @return An integer value representing the score of the player.
     */
    public int getScore()
    {
        return score;
    }
    
    /**
     * Gets the name of the player.
     * @return A String representing the name of the player.
     */
    public String getName()
    {
        return name;
    }
    
    /**
     * Gives the player 5 cards from the pack.
     */
    private void fill()
    {
        PackOfCards deck = new PackOfCards();
        int i = 0;
        while(i < card.length) {
            card[i] = deck.selectCard();
            i++;
        }
    }
    
    /**
     * Calls the fill() method and creates the method to enable the player to play the game.
     */
    public void play()
    {
        fill();
        Reader reader = new Reader();
        boolean stillPlaying = true;
        System.out.println(card[0].toString());
        int index = 1;
        while(stillPlaying = true) {
            if(reader.equals("higher") /*&& is correct*/) {
                if(card[index] > card[index - 1]) {
                    score++;
                    index++;
                    System.out.println(card[index].toString());
                }
            }
            if(reader.equals("higher") /*&& is wrong*/) {
                    score = 0;
                    index++;
                    System.out.println(card[index].toString());
                    stillPlaying = false;
            }
            if(reader.equals("lower") /*&& is correct*/) {
                score++;
                index++;
                System.out.println(card[index].toString());
            }
            if(reader.equals("lower") /*&& is wrong*/) {
                score = 0;
                index++;
                System.out.println(card[index].toString());
                stillPlaying = false;
            }
            if(reader.equals("freeze")) {
                stillPlaying = false;
            }
        }
        Reader.close();
    }
}

I coloured the text that is causing the error in red. I want it to do:
if(the current card is greater than the previous card) {
}
However, I am unsure how to do so. I get an error which complains about the > operator.

Would anyone mind helping me?

Cheers

To answer correctly, we will need to see your Card class. To take a guess though, you will need to do something similar to:

if (card[index].getValue() > card[index-1].getValue())

This is assuming your Card class has a value stored as an instance variable, and you have declared a getValue method that will return that value for your use in a calling program.

Thanks for that!
