Hello. I am a new student of java class and I struggle below question 4.

Could anyone please help me?

Thank you very much.

Answer 1

I have neatly documented the code. Happy learning !!

import java.util.ArrayList;
import java.util.Random;

class Card implements Comparable<Card> {

    int suite;
    int value;

    /*
     *  There would be 4 suits in cards
     *  Let's denote spades as 1
     *  Hearts as 2
     *  Diamonds as 3
     *  Clubs as 4
     *  The above mentioned could be anything. For simplicity let's assume them as priorities.
     */

    /*
     *  Let's only take the values between 2 and 10 inclusive at both ends
     */

    /*
     * So the value for suite can be anything between 1 and 4 inclusive at both ends
     * The value for @value can be anything between 2 and 10 inclusive at both ends
     */

    Card(int suite, int value) {
        this.suite = suite;
        this.value = value;
    }

    public int getValue() {
        return value;
    }

    public int getSuite() {
        return suite;
    }

    /*
     *  Comparable is just an interface to customize the checking between two objects
     *  For example if you want to compare two numbers how would you do that ?
     *  You would use your intuition right :D
     *  Now let's say you have to compare two mobiles
     *  You would check various factors like screen size, battery life etc
     *  If both of them have same screen size you would check battery life etc
     *  That is exactly how the Comparable interface works
     *  Just see the below function
     */

    @Override
    public int compareTo(Card o) {
        // If both cards have the same value go and compare their suite !!
        if (this.value == o.value) return this.suite - o.suite;
            // If their values itself are different then just return the smallest one !!
        else return this.value - o.value;
    }
