copied!<p>A bean machine is an upright board with evenly spaced pegs in a triangular form. Balls are dropped from the opening of the board. Every time a ball hits a peg, it has a 50% chance of falling to the left or right. Piles of balls are accumulated in the slots at the bottom of the board.</p> <p>I have the program written to where it generates the random Lefts or Rights. I want the output to be the basics of the like:</p> <pre><code>Drop a ball? Yes... LRLRLRR Drop a ball? Yes... RRLLLRR Drop a ball? Yes... LLRLLRR Drop a ball? Yes... RRLLLLL Drop a ball? Yes... LRLRRLR 0 0 0 0 0 </code></pre> <p>I have it where it displays output of the path of the ball for the Bean Machine, but I don't understand how I'm supposed to display the array that has the balls and slots with the balls in the slots...</p> <p>Here is the main parts of my code, I'm not posting the typical display methods and the such because i'm sure they are not making this problem</p> <pre><code> import java.util.Scanner; import java.util.Random; public class BeanMachine { //constants static final int LEFT = 0; static final int RIGHT = 1; static final char BALL = 'O'; //constants for options static final int STANDARD_GAME = 0; static final int QUIT = -1; //Scanner for input static Scanner keyboard = new Scanner(System.in); //two-dimensional array to represent the bean machine int ballsNo; int slotsNo; char[][]slots = new char[ballsNo][slotsNo]; //***MAIN METHOD*********************************************************** public static void main(String[] args) { displayBanner(); int userChoice = QUIT; boolean done = false; System.out.print("Enter the number of balls you want to drop: "); int ballsNo = keyboard.nextInt(); System.out.print("Enter the number of slots you want in the bean machine: "); int slotsNo = keyboard.nextInt(); do { displayMenu(); userChoice = getUserChoice(); switch (userChoice) { case STANDARD_GAME: dropBall(slotsNo); break; case QUIT: done = true; break; default: System.out.println("Continue playing?"); } } while(!done); }//end of main method //***CLEAR SLOTS*********************************************************** public void clearSlots(int ballsNo1, int slotsNo1){ for (ballsNo = 0; ballsNo < ballsNo1; ballsNo++) { for (ballsNo = 0; slotsNo < slotsNo1; slotsNo++) { slots[ballsNo][slotsNo] = 0; } } } //***DROP BALL***************************************************************** static int dropBall(int slotsNo) { int rights = 0; int position = 0; while (position < slotsNo-1){ if (Math.random() < 0.5) { System.out.println("L"); } else{ System.out.println("R"); rights++; } position++; } return rights; }//end of dropBall //***DISPLAY BOARD********************************************************** static void displayBoard(int ballsNo, int slotsNo, char [][] slots){ int count = 0; while(count<=slotsNo){ System.out.println(slots[ballsNo][slotsNo]); count++; } } }//end of class </code></pre>
