Answer to Question #179479 in Java | JSP | JSF for Bill

Question

Create one array “sign” of char type whose elements are 'H', 'D', 'S', and 'C'. Create one variable “n” of int type whose initial value is -1 and other variable named “i” of int type whose initial value is also -1. Create function named “pickCard()” of void type that randomly generate two integers. Limit first random number with range of 0 to 3,then assign randomly generated number to “i” variable. Limit second random number with range from 1 to 13, then assign the randomly generated number to “n” variable. Then, make sure “pickCard()” function can display one of “sign” array's values according to value assigned to “i” variable. Have “pickCard()” function display the value assigned to the “i” variable and meet all conditions specified in the following table

Value of i | Display

1 | A

11 | J

12 | Q

13 | K

Finally, use a while loop to call the “pickCard()” 5 times.

Answer 1

import java.util.Random;

public class Main {
    private static char[] sign = {'H', 'D', 'S', 'C'};
    private static int i = -1;
    private static int n = -1;

    public static void pickCard() {
        Random random = new Random();
        i = random.nextInt(4);
        n = random.nextInt(13) + 1;
        System.out.println(n + "|" + sign[i]);
    }

    public static void main(String[] args) {
        int j = 0;
        System.out.println("Value of n|Display");
        while (j < 5) {
            pickCard();
            j++;
        }
    }
}
