Question

The game of Craps is a dice game that involves rolling a pair of dice. At the start of each turn if the players rolls a 7, or 11 they win. Write a program that simulates how often a player would win if they rolled the dice 100 times. The program will output a message such as "The player rolled 14 sevens and 5 elevens for a total of 19 wins out of 100." The program will ask the user if they wish to run another simulation or quit. Possible Program structure Create a random number for each dice using either the API Random class or the Math classes' random method. Create a loop that will loop 100 times. Within the loop Store the random number output if it is a seven or eleven increment the value of the appropriate variable. Print out the message stating the number of sevens and elevens. Use the appropriate to type of loop to prompt the user if they like to try again or quit. Remember to provide javadoc comments and appropriate in code comments.

Random Number Generator Sample code: Random randomGenerator = new Random();//Create Random number generator objects randomGenerator.nextInt(4);//Creates a random integer between 0 and 3. or Math.random(); // creates a random double that is >= 0 and < 1.0

           //Ask the user if they want to play again
           System.out.print("Do you want to play again? Y or N: ");
           String play = scannerObject.next();
