I am creating a petals around the rose game for cs class and im lost, im unsure of how to generate six random numbers and how present 5 dice that correspond to those random numbers
this is my code so far

import java.util.Scanner;		  // allows user input from the keyboard
import java.util.Random;          // allows getting a random number


public class petals {
	 public static void main(String[] args)
	    {       
	        // variable declarations
	        Scanner keyboard = new Scanner( System.in);     // used to read user input
	        Random randomNumberGenerator = new Random(1); 	// Use 1 as the random seed, to give reproducible results 
	        											    //     between program runs.  Removing the 1 will give different
	        												//     results each time.
	        int userInput;
	        
	        // Display identifying information
						System.out.println();
	                 
	        // Display game instructions 
			System.out.println("Welcome to the Petals of the Rose puzzle.  On each turn you will  \n" 
			                 + "be presented with 5 dice values which are randomly chosen.  These  \n"
			                 + "dice represent a numerical value, which will always be even.  If   \n"
			                 + "you can correctly identify the right answer 6 times in a row, you  \n"
			                 + "become an official \"Keeper of the Rose.\" " 
			                 + "   \n"
			                 + "For example consider the following dice:  \n"
			                 + "-------  \n"
			                 + "|*    |  \n"
			                 + "|  *  |  \n"

			                 + "-------  \n"
			                 + "  \n"
			                 + "-------  \n"
			                 + "|*   *|  \n"

			// and so on...
			
			System.out.print("Enter some number to use in the following loop: ");

			if( userInput == 5) {
				System.out.println("You entered a 5.");

You can use a String array constant to hold your String representation for the dice:

public static final String[] DICE = { "draw dice1 here", "draw dice2 here", "draw dice3 here" ... };

"draw dice here" refers to the dices you print in your code.

use a Random object to generate a random nuber between 0 - 5, like:
[code]Random r = new Random();
int rand = r.nextInt(5);

after getting a value in rand, print from the DICE constant array the correct index of the dice. i.e. if you got 0, ptint the String object stored in index 0 in the DICE array.

since array indices are between 0 - 5, I refer to dice values as 0 - 5. but you can always use rand + 1 to refer to the actual dice values 1 - 6.

don't forget to import:

import java.util.Random;
