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());
[code]....
"how many time each possible total occurs"

I have problems getting the right number of times for each number of the array. Here is my code:
public static void main(String[] args) {
int[] a = { 3, 13, 5, 9, 13, 6, 9, 13, 2, 3 };
int num = 3;
int count = numbers(a, num);
for (int i = 0; i < a.length; i++) {

The game runs fine, however I have to include how many times each letter that is guessed occurs within the word. For example, if the guess is e, the program should print out: The character e occurs in 3 positions. How would I go about doing this??
/*
* A program that plays simple word guessing game. In this game the user provides a list of words to the program.
* The program randomly selects one of the words to be guessed from this list.
* The player then guesses letters in an attempt to figure out what the hidden word might be.
* The number of guesses that the user takes are tracked and reported at the end of the game.

I cannot get the right output for my program. I need to get the total number of pennies in dollar amount for the output of Total Pay. This is my program. The directions are:
Write a program that calculates the amount a person would earn over a period of time if his or her salary is one penny the first day, two pennies the second day, and continues to double each day. The program should then show the total pay at the end of the period. The output should be displayed in a dollar amount, not the number of pennies. Do not accept a number less than 1 for the number of days worked.
import java.util.Scanner;
import java.text.DecimalFormat;
public class PenniesForPay {
public static void main(String[] args) {
int numDays;
[Code] ....
totalSalary should be total number of pennies / 100....However its not picking up only day 30 of pennies which is 536,870,912 pennies and then dividing it?

I need to create a simply application that would display the results of two dice thrown five times and the total of those results. This is shown below in the attached file.
The problem is, I have a do-while loop that loops 6 times. Inside the loop, I have 2 random.nextInt(5) that generate random numbers. But how can I output the total? How can I make a variable equal to the sum of the two random numbers if the two random numbers are located inside a do-while loop?
Attached below is also the code I have thus far.
(Attached below is both files: what it needs to look like, and what it currently looks like)

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] ....

This specific assignment requires me to write a program that calculates the total sales after each football game. There are 4 types of tickets: box, sideline, premium, and general admission. After each game, data is stored in a file... then output the number of tickets sold and total sale amount. Format your output with 2 decimal places.
Okay I know there is a I/O section and wasnt sure where to post this. I need some insight on how to use file input and output as well ... Here is my program:
import javax.swing.JOptionPane;
import java.text.DecimalFormat;
public class ticketsSold
{
public static void main(String[] args)
{
String BoxSeat;
String SideLine;
[Code] ....

I'm struggling with inheritance in my assignment. The assignment states that I should use the calculatePrice() to calculate the total price and use another method to display the total. The I must overload the calculatePrice() and add a fee in the SpeedOrder() class.
My main class
package useorder;
import javax.swing.*;
public class UseOrder {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
Order.display();
[Code] .....
The problem is mainly displaying the TotalPrice field and. I can't display TotalPrice if it's not static but if it's static I can't inherit it to the SpeedOrder class to assign the total in the overloaded calculateprice method. How can I display the total in my order class and use it in my SpeedOrder class?

I don't understand that the error occurs when I don't initialize the variable myPoint. Whereas, I initialize the variable myPoint after variable declaration and before place of error.
package enumeration;
import java.util.Random;
public class Craps {
[Code]....
When I initialize the variable myPoint to zero in its decleration, the error disappear. But why? I have already initialized the variable myPoint in default case before the line of error occured..

I have one requirement where when i click on the attribute i would like to create an action and display the same in OutputText.
Ex:
This is Attribute Description outputText :
<rich:columnGroup id="CMAttributeBrowserDescriptionRow2">
<rich:column id="CMAttributeBrowserDescriptionColumn2" styleClass="selectedObj"
rendered="#{CMBrowserBean.attributePresent}" >
<!--<h:outputText id="SelectedObjectDescription1" render="true" value="#{currentAttribute.value}"/>-->
[b][quote]<h:outputText styleClass="attributeTableFont1" readonly="false" id="attributeTextdescription" disabled="false"/>[/quote][/b]
</rich:column>
</rich:columnGroup>
The action should be for :
<rich:column id="AttributeColumn2" styleClass="parentBrowserColumn">
[b]<a onclick="document.getElementById('CMBrowser:0:CMAttributeBrowserDescriptionForm:attributeTextdescription').value=#{currentAttribute.name}" >[/b]<h:outputText id="AttributeName" title="#{currentAttribute.name}" value="#{currentAttribute.name}"
styleClass="attributeValueFont" /></a>
</rich:column>
I am unable to get the text coming on outputText, when i click on the above attribute.

I'm trying to write a program that counts the number of times each number in an array occurs. In theory I understand how it work, you take the first element in the array, compare it again the rest of the array and any time it occurs in the array you increment a counter by 1. Then move onto the next element A[1] and so on...
This is what I've done so far :
public static void main(String[] args) {
int[] array = {5,6,2,5,2,2,0,1,6};
int count = 0;
for(int i = 0; i <array.length; i++) {
int val = array[i];
for(int j = i+1; j<array.length; j++)
[Code] .....
I think I'm on the right track as it correctly prints out the frequency of the first 3 elements, but I'm definitely going wrong somewhere as it just doesn't do it right after that!

When an exception occurs that will affect the entire functioning of a program, in other words, the program will not be able to do what it is intended to do, is it best just print the exception to user and run System.exit(1)? And then force the user to run the program again.

I'm having issues with JButtons and painting methods, whenever I click a grid on the board, the buttons in the JPanel disappear. Here is the board class:
package GUI;
public class Board extends JPanel implements Observer {
/**

// private static final long serialVersionUID = 1L;
private final int boardSizeX;
private final int boardSizeY;
private final int L = 20;

I know the code is messy in places, this will be fixed later, just need some pointers on how to solve the JButton issue.

Write a recursive Java method countDigitx that takes two integer numbers as input (a number n and digit x) and returns the number of times digits x occurs in number n:
For example if n=23242 and x=2 then the method should return 3 that is the number of times the number 2 found in n.

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.

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.

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?

Which is the best way to keep track of the number of the objects I've created?Is is a good practice to have a static variable, which will be incremented everytime I call a contructor?
Class circle{
private double x,y,radius;
private static count;
Circle(double x1, double y1, double radius1){
x=x1;y=y1;radius=radius1;
count++;
}

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;

Basically we have to create a calculator that it will have to keep track of the current value, and do the functions that the calculator uses.
But I have it working for the most part, but the current value does not keep...
The double " currentValue " Must stay private.
import java.util.*;
public class MemoryCaluclator {
private double currentValue;
public static void main(String[] args) {
Scanner stdIn = new Scanner(System.in);
int answer = 0;

I need to make a program that keeps track of peoples names, allows you to add a note to each name and preferably would reorganize whatever you put in by date or by spelling. (I suppose the phonebook application in cell phones is a good match, a supermarket's list of foods and prices would work as well).

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;
}
}

I have built a binary tree, from a file. In each node, I am storing each word as a string, and an int frequency for each time the word occurs. For the assignment, I need to find how many words occur only once in the file. I wrote the program, but for some reason I am getting a number different from what my professor is expecting.
As far as I know, this file has loaded into the tree correctly, because all of my other answers in the assignment are correct. What am I doing wrong?
public void findUnique() {
System.out.println("There are " + findUniqueWords(root, 0) + " unique words.");
}
private int findUniqueWords(Node subTree, int uniqueCount) {
// Base Case: At the end of the branch
if(subTree == null){
return uniqueCount;
