Generate Random Dice Rolls Using Get And Set Methods
Mar 14, 2015
The program is supposed to generate random dice rolls using the get and set methods. If the user doesn't specific how many sides the dice have, then it defaults at 6 with the constructor. The program runs but its generating 0's.
import java.util.Scanner;
public class RollOfTheDice
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
System.out.println("Time to roll the dice, how many sides do they have?");
int numSides = input.nextInt();
I am currently trying to roll 5 dice 100,000 times and output the number of times each possible total (of dots/pips) occurs. It seems to output the incorrect thing and isnt counting the occurrences properly.
public class lab_DiceRollTest { public static void main(String[] args) { int total; int total2; String valid; String isDifferent; int rolls = 100000; int d = 0;
Create a class called DiceStatistics to represent a pair of dice and the totals of their rolls. It should have an array of two Dice as a private data member (these are the Dice from Problem 1). It should also have, as a data member, an array of integers to represent the possible totals of rolling two dice.
The class should also have the following methods:
initStats() to initialize all the totals to zero. rollOnce() to roll each die once, and add one to the correct totals element printStatistics() to print the number of times each total has come up over the number of runs.
Here is my code:
public class DiceStatistics { private final int NUMBER_OF_DICE = 2; private Dice[] dice = new Dice[NUMBER_OF_DICE]; private int[] totals; private int numberOfRolls;
[Code] ....
And here is the error:
run: Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous sym type: Dice.roll at DiceStatistics.rollOnce(DiceStatistics.java:27) at DiceStatistics.main(DiceStatistics.java:55) Java Result: 1 BUILD SUCCESSFUL (total time: 0 seconds)
I know it has something to do with the fact that I need to somehow import the information from my first program "Dice" into this in order to actually get the dice statistics, but how do I do that?
The program I'm supposed to create generates a random number between one to ten. Then the program is to ask me if I wish to cross the road. If you choose to cross, the outcomes for 0-2 are "You crossed safely." For 3-5, 75% of the time it should say "RIP you got run over", and 35% of the time it should say "You crossed the street." For 6-8, 60% of the time it should say you made it.", and 40% of the time it should say "You died". For 9-10, it should say "RIP".
So far I have gotten the random number generation part working. I have up to here:
import java.util.Random; public class test4 { public static void main(String[] args) { Random random = new Random(); for(int i =0; i < 1; i++){ int num = random.nextInt(10) + 1; System.out.println("The number of cars on the street are: " + num + "Do you wish to cross the road?"); } } }
import java.util.Random; import java.util.Scanner; public class DiceGame6 { public static void main(String[] args){ Scanner stdIn = new Scanner(System.in); System.out.println("Welcome to Computer Dice!"); System.out.println("-------------------------------"); System.out.println("You will first roll your dice
[code]....
How would I get the code to count the number of times something occurred. In the end it's suppose to count how many times I played the game and how many times I've won vs lost.
How would I get java to generate a random number from 0-2? all I've been able to find on random numbers is math.random which gives you from .0 to .10. you can multiply this by 10 to get 1-10 or by 100 to get 1-100 but how to make it so java will simply let me tell it the rand of numbers I want or get a random number in a range that is not a multiple of 10. and I can't seem to find anything about it anywhere.
I am currently taking a class in the field. My assignment is to generate 6 unique random numbers using a "Do While" expression. I might be mistaken but doesnt the inner loop execute first and then it works its way out? With this logic I believe my code should work but then again its not.
public class DoLottery { public static void main (String args[]) { int max= 10; int random; int random2; int random3;
[code]...
I originally had output at the end but decided to comment it out to see if code would execute if I placed it every time the test was true.
I am trying to get random shapes to generate automatically. I was able to get just three shapes to generate but nothing random. When I added the random code now only the frame shows up and no shapes. I also keep getting an error with frame.setVisible(true). It says identifier expected. Here is what I have so far:
Main program:
import javax.swing.*; import java.awt.*; import java.util.Random; public class ShapeGen { public static void main(String [] args) { //Create window and set title draw panel = new Draw();
[Code] ....
This is the draw program to generate random shapes:
import javax.swing.*; import java.awt.*; import java.util.Random; public class draw extends JPanel { public draw(Color backColor) { setBackground(backColor);
I have my code which will generate a random string using an ArrayList. However, I aso want to have it generate them in random lengths, not just using all the chars and numbers.
Trying to generate random integers, based off user-input for amount of integers, and then sort them into an array. The problem is that the second method needs to be int[] but I cannot figure out what to make the return result. The instructions say it needs to be an int[] in the UML diagram, so I know it's not supposed to be void.
Java Code:
public void generateNewSecret() { Random rand = new Random();{ for (int i=0; i<numDigitsSet; i++) { secretNumber[i]= rand.nextInt(10); System.out.println("" + secretNumber[i]);
I'm trying to generate random 100 numbers, from 0 to 9, in an array using Math.random, but it only outputs 0s which is very confusing to me. Also, I need to be able to count how many different integers there are like 0s, 1s, 2s... 8s, 9s.
Here's my code, I only got as far as the array then got stumped on the counting part.
import java.util.Arrays; public class countDigits { public static void main(String[] args) { //Create random generator and values int numbers = (int)(Math.random() * 10); int arrayCount = 1;
Instruction: You work for a telemarketing company and you are required to write a JAVA program that will generate a random phone number. (talk about a real-world application)
-The phone number should consist of 10 digits -The first 3 are the area code and should not begin with 0, 8 or 9 -The second 3 digits should not be greater than 742 and not less than 100. -The last 4 digits can be any digits -Print the number using the following format: "(xxx)-xxx-xxxx", this way it will look like a real phone number (use decimal formatting)
by this : Generating Random Numbers Using arithmetic operations
To simulate it, the program will generate a random number between 0 and 19, which represents the location in the array (i.e. index number). Then, the 3 numbers to the left and right of this location should be reset to the value 0. If there isn't 3 numbers to the left and right you may assume a lesser number depending on the boundaries of the array.
How to reset the numbers to 0 in the final array ?
I'm finishing up this assignment, and I'm stuck. These are the last 2 instructions:
. Roll each of the Dice by invoking the roll method on each Dice in the array. . Keep track of the totals sum of all the dice in the array. Be sure to roll the dice array at least 10000 times.
How to finish it up?
Here's my code so far:
package homework3;
import java.util.Random; public class Dice { private int numberShowing; private final int numberOfSides; private static final Random randomNumber = new Random(); public Dice() { numberOfSides = 6;
So I need to generate 10 random integers in the range 1-20 but i have to store them in an array called numbers. Then I have to call a method called displayArray which displays the contents of the array and for the assignment i have to use a for loop to traverse the array. The method header for the displayArray method is:
public static void displayArray(int[] array)
This is what I have done
public class RandomIntegers { static int numbers = 0; public static void displayArray(int[] array) { System.out.println(numbers + "Numbers Generated");
I tried out doing number (generated randomly) != (another number) but that does not work. If I for example want a number between 1 and 10, but I do not want the number 5, what can I do in order to make this happen?
in my progrm there are three diff array of objects...namely garments..gadgets and home app...now one who buys from each of these sections will have to make a bill at last...when he choses to make the bill he will be shown the list of products he bought and their details (like price...brand...etc)...so i thought that while he orders each product(which is done in a previous method called purchase()...)....(each product is stored as an object in there diif arrays namely garments...gadgets ...appliances)....each of those object will be copied in a new array in a diif class...then that array print will give me the desired result...
is this approach correct...?and if its correct then how can i pull out a specific obj frm a stored array of object and then save it in a new array....?
Write a method called statistic that simulates the rolling of two dice 1000 times. (1000 times is a parameter of the method statistic).The program should have no input, and should use pseudo random numbers to simulate the rolls (one random number per die). Store the sum resulting from each roll of two dice, determine the number of times each 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 was rolled. The out produced by the program is:
public static void main(String[] args) { statistic(1000); } public static void statistic(int number) { Random randomNumbers = new Random();

i have been trying for hours to make it look like the output above but no luck. I was wondering if there's any other way writing the code without using arrays.
The instructions are to "write a program to simulate tossing a pair of 11-sided dice and determine the percentage of times each possible combination of the dice is rolled... then ask the user to enter the number of sides on a die" The code is all provided here, I just have to put it in the right spots. (Side note, I cannot use arrays.) Here's the original file I was given to work with:
Java Code:
import java.util.Random; import java.util.Scanner; public class DiceProbability { public static void main(String[] args) { //Declare and initialize variables and objects //Input: ask user for number of rolls and number of sides on a die //Print heading for output table
[Code] ....
When I run it, I get something like this (just a part of my output):
Please enter the number of sides on a die: 6 Please enter the number of rolls: 2
I want to write a small Hi Lo Betting Dice program that satisfies these conditions :
A player places a bet on whether the sum of two dice will come up High (totalling 8 or higher), Low (totalling 6 or less) or Sevens (totalling exactly 7). If the player wins, he receives a payout based on the schedule given in the table below:
Choice Payout High 1 x Wager Low 1 x Wager Sevens 4 x Wager
The player will start with $100 for wagering. If the player chooses to wager $0 or if he runs out of money, the program should end. Otherwise it should ask him whether he's wagering on High, Low or Sevens, display the results of the die rolls, and update his money total accordingly.
some sample output:
You have 100 dollars. Enter an amount to bet (0 to quit): 50 High, low or sevens (H/L/S): H Die 1 rolls: 1 Die 2 rolls: 5 Total of two dice is: 6 You lost!
You have 50 dollars. Enter an amount to bet (0 to quit): 25 High, low or sevens (H/L/S): L Die 1 rolls: 6 Die 2 rolls: 2 Total of two dice is: 8 You lost!
You have 25 dollars. Enter an amount to bet (0 to quit): 12 High, low or sevens (H/L/S): H Die 1 rolls: 2 Die 2 rolls: 6 Total of two dice is: 8 You won 12 dollars!
I have written some code but now i am stuck at the logic ...
package com.peg.hilodice; import java.util.Scanner; public class DiceGame { public static void main(String[] args) { // TODO Auto-generated method stub int money = 100; int bet;
I am making a Dice Roll GUI and I have most of it down and I only need this constructor to work for the program to work (I think). I don't know where to place the constructor, I tried placing it around the RollButton class but it still didn't work and gave me java error constructor in class cannot be applied to given types
Here's my constructor:
private JPanel panel; public RollButton(JPanel panel){ this.panel = panel; }
package dicedemo; public class DiceDemo { /** * @param args the command line arguments */ public static void main(String[] args) { // TODO code application logic here
final int Die1_SIDES = 6; // Number of side of dice 1 final int Die2_SIDES = 6; // Number of side of dice 2 // Create two instances of the Die class.
[Code] ....
I need converting the number output to text: example one, two, three, etc.
I have this really a graphics program that I'm working on which displays a single die, and right now it is set to the default 6 sides. I need to change it to 12. Here is the program:
/** * This class encapsulates a simple dice game. The number of dice and number of sides on those dice are given by instance variables. The outcomes ArrayList holds a list of all possible outcomes of throwing that number of dice with that number of sides. * * If there were 2 dice, each with 6 sides, then possible outcomes would include 1 1, 1 2, 1 3, 1 4, 1 5, 1 6, 2 1, 2 2, 2 3, and so on. * * Your task is to complete the methods that calculate the possible outcomes. One method calculates outcomes allowing for repeated numbers. One method calculates the outcomes of a fictional dice game where repeated numbers cannot occur. * * You must use recursion. This is a variation on the permutations problem from the book. */
public class Dice { private static int numberOfSides; private static int numberOfDice; public ArrayList<String> outcomes;
[code]...
I manage to calculate the numberOfOutcomes correctly, but then get a nullPointerException. Also, is there a way that I can use getNumberOf Outcomes without making it static? The testing code that the teacher provided is using it in another class and if I make it static, then it doesn't work in that file.
