Answer to Question #179808 in Java | JSP | JSF for Phil

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, n, variable. Have pickCard() function display the value assigned to the “i” variable and meet all conditions specified in the following table:

Value of i = 1, Display = A

Value of i = 11, Display = J

Value of i = 12, Display = Q

Value of i = 13, Display = K

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

Answer 1

public class TaskArray {


	public static void main(String[] args) {
		
		char[] sign = { 'A', 'J', 'D', 'K' };
		int n = -1;
		int i = -1;
		int k = 0;
		while (k < 5) {
			pickCard(i, n, sign);
			k++;
		}


	}


	public static void pickCard(int i, int n, char[] sign) {
		int firstRandomNumber = (int) (Math.random() * 3);
		i = firstRandomNumber;
		for (int j = 0; j < sign.length; j++) {
			int secodRandomNumber = (int) (1 + Math.random() * 13);
			n = secodRandomNumber;
			System.out.println(" Value of i =" + n);
			System.out.println(" Display =" + sign[j]);
			System.out.println();
		}


	}
