Keep Track Of Result Of Each Roll Using Array

Mar 8, 2014

The code I have below asks the user how many times you want to roll the dice. It rolls dice 1 and dice 2 randomly and gives the total. Now, I'm trying to keep track of the result of each roll using an array that is indexed by the sum of the roll of the two dice. Then I want to output my result in a table that shows each value (from 2 - 12)) and the number of times that value was rolled. I would like to do this preferably with the JTextArea class, but it doesn't have to be. I keep getting errors.The code below works for the dice rolling in the 1st paragraph. I took out all the bad code I was trying to use for the 2nd paragraph.

package Part2pack;
import java.util.Random;
import javax.swing.JOptionPane;
class Dice{
public static void main (String args[])
{
String input = " ";
int count = 0,dice1,dice2;

[code]....

Roll Two Dice / Add Them Together And Print The Result

Oct 23, 2014

Write a program that rolls two dice, adds the numbers and prints out the results. I have managed to do this but we have to make it a horizontal table instead of a vertical one. like the attached file "CORRECT", right now i only get the "NOTCORRECT". i have tried for hours to fix this but i can't.

import java.util.Random;

public class Statistikk {
public static void skrivStatistikk() {
Random rand = new Random();
int[] antall = new int[13]; {

[Code] .....

(Antall is basically frequency|side is the same as a face of a die)

Here is my code, does my code need improvement? Or is it my printf that is the issue? i've tried deleting the 's and adding the printf to the same line, but nothing worked.

Increment Array And Got Unexpected Result

Aug 16, 2014

Java Code:

char array[] = new char[10];
int i = 0;
array[i++] = (char)('A' + i);
System.out.println("char for array is: " + array[0]); mh_sh_highlight_all('java');

However, the result for array[0] is B. Not A. from my understanding, the array[0] should be 'A'.

Multi-sided Dice - Keep Track Of Total Sum Of All Dice In Array

May 7, 2014

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;

[Code] ....

How To Change Value In Array Through User Input And Print Out Result

Dec 14, 2014

I have to do a small program about parking. In the 2-d array (parking lot), contains different kinds of cars, the user have to :

1)enter which car he wanna move,
2)what direction (w,a,s,d) and after that,
3) how many moves( not out of bound) he wants to make, and finally
4) we print out the new parking lot for his next move

And i am stuck at how to move the car to corresponding position and then prompt user for the next move?

For example:

I want to move A to the right by 1 (d)

擷取.PNG
print result:
擷取1.PNG

How do I do that? The code that i have right now

public class CarParkGame {
public static void main( String [] args) {
  String carPark[][] = new String [6][6] ;
carPark[0] = new String[] {"A","A","A","0","0","0"};
carPark[1] = new String[] {"b","0","0","0","0","c"};
carPark[2] = new String[] {"b","X","X","0","0","c","<exit>"};

[Code] .....

Selection Sort Method - Sorting Array And Return Result Of Each Step

Nov 20, 2014

This time I am having difficulties with selection sort method, but not with the method itself (I think). So I need to sort an array and return the result of each step.

This is the main code:

public class Functionality {
public static int[][] selctionsort(int[] a) {
for (int i=0; i<a.length; i++) {
int least = i;
for (int j=i+1; j<a.length; j++)

[Code] ....

And this is the Test folder:

import static org.junit.Assert.assertArrayEquals;
 public class PublicTests {
public static void main(String[] args) {
int[] a = new int[] { 35, 7, 63, 42, 24, 21 };
int[][] b = new int[][] { new int[] { 7, 35, 63, 42, 24, 21 },

[Code] ....

Now I am not sure what should I write in return since the 2nd (test) project has int[][] and in my main project I am working with int [].

Dice Roll GUI - Where To Place Constructor

Feb 17, 2014

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;
}

Here's my code:

All Possible Outcomes Of Dice Roll Using Recursion

Nov 26, 2014

Here is what I have so far:

/**
* 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.

Add Program In Order To Dice To Roll

May 8, 2014

what code I should add to my program in order to get these dice to roll. The program, according to my teacher, is CORRECT so far, so I'm not going to change anything. I just need to know how to roll the 2 dice I added in. I just want to get it done. No math.Random. The direction is: Roll each of the Dice by invoking the roll method on each Dice in the array.

My code:

//Dice.java
package homework3;
import java.util.Random;
public class Dice {
private int numberShowing;
private int numberOfSides;
private static final Random randomNumber = new Random();

Simulating Roll Of D6 Dice With Java Code

Apr 21, 2015

I am trying to figure out how to simulate an ability score calculation for an RPG character creation. The way I want to do it is to have 5 d6 dice rolled and then the best three of the 5 rolls are added together for a maximum of 18 points and a minimum of 3 points.

Now I know how to generate random numbers, but I do not know how to have the best 3 picked out. What I have right now is super simple.

package javaapplication12;
import java.util.Random;
public class JavaApplication12 {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {

[Code] ....

So this gives me my five rolls but then have the code pick out the best three every time the program is run is kind of an issue for me.

Creates Two Die Objects And Roll Them Display The Values

May 4, 2014

I've written a die program, and i want the user to type any key in order to continue, how do i achieve this ?

I have already created a Die class, i just want to implement the main method now.

PHP Code:

package test;

/* This program demonstrates the use of a user-defined class

public class RollingDice {
// Creates two Die objects and rolls them display the values.
public static void main (String[] args) {
Die die1 = new Die();
System.out.println("Roll the die ")
}
} mh_sh_highlight_all('php');

What should i add after System.out.println, So that the user types (any key, or types "Enter" for example, for the die to roll). i dont want the die to roll by itself i Want the user to interact with the program in order for it to roll.

How To Track Player Positioning

Nov 25, 2014

So I have a player an enemy and enemy bounds the enemy can go. I need to have the enemy track my position and when I go into the position (I am using a collision method for this) the enemy comes over at a speed of 1. My problem is the enemy jumps to me and then follows at speed of 2 (2 is the player speed). The code is wrong this is why it is jumping and I have my other problems. so my question is what is a good solution for this? I am trying to make a method to track playerposition() so what I am thinking I could do is find x, y of player then store those into an array and return the array to Enemy so he tracks.

player.java
public class Player{
int x = 100; // Location of player
int y = 200; // location of player
int xa = 0; // Representation of where the player goes
int ya = 0; // Representation of where the player goes
private int speed = 2;

[Code] .....

Please note this is not the entire code I have cut some things out that did not need to be there. Also, the code is just to get an idea of what I was thinking of doing. The ideas that are came up with are not meant to be a reflection of what I already have but, what I could add or replace.

How To Keep Track Of Percent Full

May 20, 2014

I'm trying to make a canteen class that holds water. It holds two quarts of water and two quarts is 100%.

public double maxVolume;
public int percentFull;

Right now the Canteen is empty.

public void Canteen()
{
percentFull=0;
maxVolume=0;
}

And right now I'm trying to make a constructor that specifies the amount of liquid the canteen can hold and specifies the percent full.

public Canteen(double maxVolume, int percentFull)
{
}

Should I make this second Canteen an integer, a double, or something else? Also, how do I make sure the Canteen never reaches higher than 100%. I'm also curious how I can keep maxVolume and percentFull connected so the % of water is consistent with the number of quarts(2) the Canteen can hold.

Who Keeps Track Of Which JComponent Has Focus

Aug 31, 2014

I have two JFrames: frame1 and frame2. frame2 currently has focus, and I want to determine which component of frame1 would have focus if I were to switch focus to frame1, hopefully without actually temporarily changing focus.

Is it the KeyboardFocusManager who keeps track of which element in each frame has focus? Or does each container itself keep track? How does Java figure out which element in a frame gets focus when I switch to that window?

Keep Track Of Output - How Many Times Each Total Occurs

Jan 23, 2015

I am currently truing to make this class instantiate 100,000 dice rolls of 2 dice. And I also need to keep track of how many times each possible total occurs and I am having trouble outputting the result. Right now when I run my code it is just showing the results of each of the 100,000 roles.

public class ltefera_DiceRollTest {
public static void main(String[] args) {
ltefera_DiceRoll diceRoll = new ltefera_DiceRoll(10);
System.out.println("Total # of pips" + "
");
diceRoll.printArray();
System.out.println(diceRoll.countDice(2));
System.out.println(diceRoll.isArrayDataValid());
System.out.println(diceRoll.getTotal());
System.out.println(diceRoll.allDifferent());

Keeping Track Of Team Standings In A League

Apr 18, 2014

Here are my conditions: You are developing a program to keep track of team standings in a league. When a game is played, the winning team (the team with the higher score) gets 2 points and the losing team gets no points. If there is a tie, both teams get 1 point. The order of the standings must be adjusted whenever the results of a game between two teams are reported. The following class records the results of one game.

public class GameResult
{
public String homeTeam() // name of home team
{ /* code not shown */ }

public String awayTeam() // name of away team

[Code] ....

The class TeamStandings stores information on the team standings. A partial declaration is shown below.

public class TeamStandings
{
TeamInfo[] standings; // maintained in decreasing order by points,
// teams with equal points can be in any order
public void recordGameResult(GameResult result)

[Code] ....

And here is the actual question:

Write the method adjust. The method adjust should increment the team points for the team found at the index position in standings by the amount given by the parameter points. In addition, the position of the team found at index in standings should be changed to maintain standings in decreasing order by points; teams for which points are equal can appear in any order.

And here is what I have so far:

private void adjust(int index, int points)
{
int Score[] = new int[standings.length]
for ( int i=0; i <= standings.length; i++)
{
Score[i] = index, points;
}
}

Priority Queue In Java Which Keeps Track Of Each Node Position

May 4, 2014

I'm working on a lab for my class. I need to create a Priority Queue in Java using an array list. The kicker is that each node has to have a "handle" which is just an object which contains the index of of the node that it's associated with. I know that sounds weird but we have to implement it this way. Anyway, my priority queue seem to work fine except the handle values apparently aren't updating correctly because I fail the handle test. Also, I run into problems with handles only after extractMin() is called, so I figured the problem would be somewhere in that method but I've been through it a million times and it looks good to me.

Here is my Priority Queue Class:

package lab3;
 import java.util.ArrayList;
 /**
* A priority queue class supporting operations needed for
* Dijkstra's algorithm.
*/
class PriorityQueue<T> {
final static int INF = 1000000000;
ArrayList<PQNode<T>> queue;
 
[Code] ....

I can post the tests too but I don't know if that would do much good. Just know that the queue works as is should, but the handles don't point to the right nodes after extractMin() is utilized.

Swing/AWT/SWT :: Track Down Why SetViewPortView On A JScrollPane Is Taking So Long

Apr 27, 2014

I've built up an unreasonably large and unreasonably complicated JPanel. Unfortunately, when I use setViewportView to add it to a JScrollPane, a get an extended UI freeze—that operation takes several seconds. I'm trying to figure out what's taking so long. I've tried some fairly extreme things, like overriding the paintComponent, PaintComponents, paintChildren, paint, repaint, validate, revalidate, and validateTree methods in the panel with no-ops to try to figure out what's taking so long, but to no avail. I've tried validating the JPanel before adding it, but that has no effect. If I override the addImpl method of the scroll pane, that makes things quick, but it doesn't really narrow things down much.
