Randomly Distribute People In Groups

Jan 18, 2014

I want to create a program that takes n number of people (String vector) and assigns them a random group number (int) the range from 1 to k. The number n is evenly divided by k.

I have created a program that associates every String with a random int number. There is however the problem that the random generator just gives a random number, but doesn't make an equal number of people for each group. Which means even if the numbers are random, some of the numbers happen to come up more times than others.

How can I write, to make sure that each number is generated the same amount of times?

EJB / EE :: Use Asynchronous Annotation In Distribute Environment

Jul 18, 2014

Can we use EJB @Asynchronous annotation in distribute environment. I know we can use it but I want to know its Advisable or not. Because It's not advisable to manage user thread in Distribute environment like EJB container .Earlier if we want to make Asyn call then we use JMS. But now they added @Asynchronous annotation with Future Class to achieve the same result.

JavaFX Adding Several Object Groups On Event

Jun 18, 2014

We are doing a Timeline project, So this is what i want to do:

Pressing a "New Event" button opens the New event window where you are supposed to write input in three fields, name, date, and information. There is also a button "Create" that when i press that button, i want to take all the input from the fields and save/send it to our database, and go back to the timeline GUI. With this, i want a new event object to be created(in this case i have done several shapes in a group) so basically a new group i want to be added. All the information is suppose to be taken from the database right after i create it.

I'm pretty stuck on how i should solve this, for the moment have a group called event that i add on the canvas. First thing that pops up in my head is a void method that draws the event, or maybe a temporary array.. P

package application;
import controllers.CreateEventController;
import application.EventPop;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Cursor;

Generate JAR File To Distribute Having Multiple Projects

Jan 20, 2015

I have an application separated into three different projects - core, command line version and Web UI version.

Core contains all the business logic in several services classes. Command line version and Web UI version both uses the core project services.

Command line have main class which call services from core. Web UI version is Spring base application using same services from core.

Java Code:

CoreProject
- src
- Service Classes (code here use thirdParty jars and core_file.txt)
- lib
- thirdParty.jar
- core_file.txt mh_sh_highlight_all('java');

[Code] ....

Now I want to give two separate versions to client.

Command line version to run as service in Windows andUI version to deploy in their server.

With above structure I create the cmdline.jar but when I am trying to run with

Java Code: java -jar cmdline.jar mh_sh_highlight_all('java');

I am getting java.lang.NoClassDefFoundError exception for the service classes in core. So my question is how to pack/generate jar for this kind of distribution?

Java Program That Keeps Track Of People Names

Jan 13, 2015

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).

Allowing A User To Enter X Number Of People Into Array

Feb 5, 2014

I am starting a program that is dealing with arrays. My issue, allowing a user to enter 'x' number of people into an array. How do I first allow them to enter the size of an array, and then enter strings (list) into that array. In addition to this, I need to specify the number of boxes of cookies sold by each person and keep a tally of the number of people selling cookies in each category (e.g. 1-10, 11-20...etc). Instead of having a number 100000, I want the user to enter that size, 'x'.

import java.util.Scanner;
public class cookie {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int x = 100;
double saleCount[] = new double [x];
String[] girlScout = new String[100000];

Does Either Of These Randomly Generate Both 0 And 1?

Nov 22, 2014

"which code is best for randomly generating integer 0 or 1". Haven't gotten my grade back yet but in reading these during the test I didn't think any of these would kick out both of those numbers, but there was no "none of the above" option on the test.This is exactly how it appeared on the test:

A) (int)Math.random() + 1
B) (int)(Math.random() + 0.2)
C) (int)Math.random()
D) (int)(Math.random() + 0.8)
E) (int)(Math.random() + 0.5)

I've tried all of them in the cs lab 100 times each and none of them generated both numbers. 'A' kicked out 1 every time. 'B,D and E' kicked out 0.2, 0.8 and 0.5 respectively each time, and 'C' kicked out 0. Did I just not run them enough times for the result to change or am I right in thinking there's a glitch on the test?

Randomly Shuffling Cards

Apr 8, 2015

i'm trying to make a random card shuffler but the output would sometimes have same value multiple times. For example it might print out A5 at the fifth index then print out A5 again as the 32 index.

public class randomGenerateCards {
public static void main(String[] args) {
String temp;
String[] cards = new String[]
{ "A1", "A2", "A3", "A4", "A5", "A6", "A7", "A8", "A9", "A10", "A11",
"A12", "A13", "S1", "S2", "S3", "S4", "S5", "S6", "S7", "S8",
"S9", "S10", "S11", "S12", "S13", "H1", "H2", "H3", "H4", "H5",
"H6", "H7", "H8", "H9", "H10", "H11", "H12", "H13", "D1", "D2",
"D3", "D4", "D5", "D6", "D7", "D8", "D9", "D10", "D11", "D12",

Randomly Filling Tic Tac Toe Board

Oct 19, 2014

So I an assignment in Java to write a code which will randomly populate squares in a Tic Tac Toe Board. I pretty much have it I think, but I cannot get the 'O' to appear on the board, some squares will be blank. We were told to use the Random utility to generate the squares. I am attaching the .gif's which are used. Here is my code:

import javax.swing.*;
import java.awt.*;
import java.util.Random;
public class LandryTicTacToe extends JFrame
{
/**
*
*/
private static final long serialVersionUID = -8781512780135301721L;
private final int HEIGHT = 450;//Set value for Height
private final int WIDTH = 500;//Set value for Width
private static JButton [] button = new JButton[9];//Declare array of Buttons

[Code] .....

[attachment=37084:TicTac0.gif][attachment=37085:TicTacX.gif]

Instructions Given to me:

Display a frame that contains nine labels, arranged like a Tic Tac Toe board. A label may display an image icon for X, an image icon for O, or nothing. Display images randomly in each label. Use the Random class to generate 0, 1, or 2, which corresponds to displaying an X image, an O image, or nothing.

How To Make Animation Stop Randomly

Dec 28, 2014

I am trying to program a slot machine and as of now, I am trying to make my slots spin and randomly stop on one of the graphics. Right now, I am having difficultly making the animation/slot stop randomly.

Previously, I tried using a randomly set timer that would cancel the execution, but the image did not appear/stop on the screen.Right now, I am using a random generator and a while to say that if it is a certain number, then stop the image.Here's what I tried:

import java.applet.*;

import hsa.*;
import java.util.Random;

public class SlotGraphics

int y = -100;

Unable To Print Out Randomly Generated Array

i am trying to print out a randomly generated array, but i only get

[I@7852e922

i did some research and the "[" is for arrays, "I" is for the int and "@" is the hash. and the rest is some sort of hex. I need to override this in a way, but i can't seem to find out how.
this is my current code:

int myint[] = fyll();
System.out.println(myint);

Create Permutation Method Where J Is Chosen Randomly From 0 To I

Apr 16, 2015

I need figuring this problem out. It appears that I am attempting to generate a permutation of the string "ABCDEF" 720,000 times using this method:

In the second method, j is chosen randomly in the range from 0 to i (inclusive).

Once the permutations are generated, the program will proceed in counting the number of times each permutation occurs, calculating the chi square statistic of the situation, and creating the chi square distribution with 719 degrees of freedom, then outputting the statistic and the chi square probability of the permutations. The generatePermutation method is where all the magic happens. Only trouble, I can't figure out what I equals to. The times where I think I have i as a correct value only give me the program outputted as 1.0 probability every time. What it needs to be doing is outputting variable probability as a number always between 0 and 1, not 1 all the time. Here is my code:

assignment7part2.java:
package math3323assignment7;
import java.util.HashMap;
import java.util.Map;
import java.util.Map.Entry;
import java.util.Random;
import org.apache.commons.math3.distribution.ChiSquaredDistribution;
import com.google.common.collect.Multiset;
import com.google.common.collect.TreeMultiset;

[Code] ....

i is meant to step through the index of the array, but I can't figure out what i is.

Randomly Throw Two Dice And Display Their Values

Mar 25, 2014

Dice are used in many games. One die can be thrown to randomly show a value from 1 through 6.

Design a Die class that can hold an integer data field for a value (from1 to 6).

Include a constructor that randomly assigns a value to a die object. Appendix D contains information on generating randomnumbers. To fully understand the process, you must learn more about Java classes and methods. However, for now, you can copy the following statement to generate a random number between 1 and 6 and assign it to a variable. Using this statement assumes you have assigned appropriate values to the static constants.

randomValue = ((int)(Math.random() * 100) % HIGHEST_DIE_VALUE +
LOWEST_DIE_VALUE);

Also include a method in the class to return a die's value. Save the class as

Die.java.

Write an application that randomly "throws" two dice and displays their values. After you read the chapter Making Decisions, you will be able to have the game determine the higher die. For now, just observe how the values change as you execute the program multiple times. Save the application as TwoDice.java.
