CallNumber Method For Bingo Simulation

May 26, 2014

As you may have known, I'm creating a Bingo simulator from scratch.

Precondition: an n amount of randomly generated cards are created.

Postcondition: After a number is called, cards that has that number will have its value be true.

For example:

Precondition

Java Code:

Card 1 //Name of card

1 24 32 48 63
2 22 41 51 64
3 16 37 52 61
4 19 33 57 72
5 20 34 54 71 //Card with numbers

false false false false false
false false false false false
false false false false false
false false false false false
false false false false false //Card with boolean values to indicate marked values

[Code] .....

So what I want to do is have a method that allows me to use the callRandomNumber method so that the matrix location with that random value is marked true for all of the boards.

Random Bingo Card Generator

May 26, 2014

I'm trying to create a program that will be able to generate random Bingo cards. This is what I have so far.

Java Code:

import java.util.Random;
public class BingoCard
{
private int[][] card;

public BingoCard(Random random)
{
card = new int[5][5];
for (int c = 0; c < 5; c++)

[code]...

The problem with this program is that even with the checkForDuplicateValues method, which checks for duplicate values of a column and replaces the values, it still prints out bingo cards with duplicate values!

Bingo Game - How To Call 5 Numbers From Array

Aug 18, 2014

I am writing a Bingo program for a class and have reached a roadblock. How do I call 5 numbers from the array and where do I store them so I can populate them back into my JLabels on the Bingo card. I'm sure there are more complicated ways to do this, but I'd like to keep it simple so I actually understand the process. I understand that I will need to shuffle the numbers in the array before choosing them, but I also am not sure how to do that.

int [] BArray = {1,2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15};
for (int index = 0; index > 5; index++) {
}

Bingo Board - Having Array To Fill A Grid

Dec 16, 2014

I am attempting to make a 5x5 bingo board. My array generates 75 numbers(15 per bingo letter) and displays them in a random order. What I am having trouble figuring out is how to fill the 5x5 grid with 25 numbers from my array. And yes, my code is probably much longer and much more redundant than it needs to be. Also, I think I'm using cells and grids terribly wrong (possibly the entire java language) but I'm not sure.

import java.util.*;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JLabel;
import java.awt.event.*;

Simulation - Two Cars Are Going To Race Against Each Other

Oct 22, 2014

I was thinking to make a game where two cars are going to race against each other. I already have two gif pictures which are the cars. I do now have a background and a racer track. So we can start from here.

I have made a object with construction which I called Racers. Inside that, i wrote a PaintWindow (Where the window and much more is inside), -car1, -car2. All these is private. So I made something like this now:

package p2;
public class Race {
private Object window;
private Car car1;
private Car car2;
public Race(PaintWindow window, Car c1, Car c2) {

[Code] .....

But the problem is now that im kinda lost and I dont really know what to write anymore. How can I get a for example a green background on the whole PaintWindow with two Racers tracks and inside the racers tracks (Each car have each track) does it have to be cars. So I need to somehow import the cars inside it too. But thats the problem I need. that I dont really know what more to do. To make it easier, I have a Main-method in another class.

public static void main(String[] args) {
PaintWindow window = new PaintWindow();
Car c1 = new Car(new ImageIcon("C:/Users/Sarah/Desktop/CarBlue.GIF"));
Car c2 = new Car(new ImageIcon("C:Users/Sarah/Desktop/CarRed.GIF"));
Race race = new Race(window,c1,c2);
race.action();
if(args.length>0) {
Paintwindow.pause(2000);
window.dispose();

SSO Kerberos Simulation In Java

Apr 20, 2014

I'd like to learn more in Java security, namly Kerberos and SSO. The question is weather I have too weak laptop. I have 8 GB ram. How many virtualbox instances od I have to run in order to JAAS, SSO kerberos demo to simulate. For instance VM with Windows 2008 Server -> 3 GB RAM, Centos VM -> 1GB. Is 8 GB RAM in my laptop not too little?

BTW

I do not have yet experience in SSO/Kreberos but I want to know what to do in order to simulate and exercise.

Print Queue Using Priority Q Simulation?

Nov 28, 2014

I have a class "ExecuteJob" which has Print Q in the form of Priority Q.

You can keep adding job to the Q by calling one of the method in the class. However, and object cant do things simultaneity can it? While im adding a new job to the print queue, can it be executing and existing job in the print Q.

To achieve that, I would need to implement process and threads? I believe am I right? So that adding a job is independent to being removed?

Traffic Light Simulation Using Multithreading

Feb 2, 2015

I am writing a simple program to simulate a traffic light. What I want is to make them glow after each 1 second, one by one. For example: Firstly Red, then after 10 seconds, red will be put to off and yellow will start glowing and then accordingly green. This process shall continue incessantly (Just for experimental purpose). I have some arrangement done but could not figure out how to put them together in run() method of Runnable interface. I know how interthread communication works. But could not find any logic in this case when three threads will run together.

import java.awt.event.*;
import javax.swing.*;
public class TrafficLight extends JFrame implements Runnable

Simple 2D Optics Simulation Program

Sep 13, 2014

I'm very new to Java (I literally started learning it yesterday) and I've been working on a simple program that's meant to simulate interactions between optics objects and light rays.

Everything has been going really well, except that my mirrors only reflect the first ray that comes in contact with them.

Here's a screenshot : 2014-09-13 at 7.39.23 PM.jpg

I wrote 7 classes:

Main class to create the optics objectOptics class. the most important class that uses a recursive function to detect the nearest intersection point of a ray with the nearest optics object. It then calculates a reflected ray and inputs it back into the function until no intersections are found or the max recursion depth is met.Ray. creates a rays (in parametric form O + tD where O is the origin, D is the direction and t is a non-negative scalar)Object. empty abstract class used for polymorphism (so when i add more optics objects like prisms and lenses they'll share the object type)Mirror. Basically a line segment created with the Line classLine. Creates a line segmentDraw. JComponent with paintComponent function that loops through an array of shapes and draws them to the screen.

What I know so far is that the problem boils down to the checkRay() function in the Optics class. When a mirror has already reflected a ray, the line:

Intersection sec = new Intersection(ray,(Mirror)obj);

creates an intersection with a null point.

I debugged it line by line and found the problem was that my variable 't' (that is the parameter for the parametric line which represents the mirror) in the Intersection class got big values when it's meant to be between 0 and 1 (since it's a line segment), which resulted in the function returning null (as it should when 't' is not between 0 and 1).

I've confirmed with tests that this has nothing to do with the specific mirror or angle of incidence. It only occurs when a mirror has already been intersected with by a ray.

I've found out that my function:

public PVector getNormal(PVector D){
D.normalize();
return new PVector(D.y,-D.x);
}

Changes the value of the 'D' PVector of the mirror inside my 'objects' ArrayList. How can it access the private PVector 'D' from outside the Mirror class? This normalization to the direction vector is what causes the Intersection class to return null the second time around!

The problem was that in the getNormal function, the input vector argument was a reference to the 'D' vector for the mirror in my 'objects' ArrayList so the .normalize() function acted upon the original vector, changing it's value and screwing things up. The two classes I talked about:

Optics: (note line 64. this line returns a null intersection when it shouldn't)

package ofer.davidson;
 import java.util.ArrayList;
 public class Optics {
 //Arrays to store all the optics objects and rays that are created
ArrayList<Object> objects;
ArrayList<Ray> rays;
 
[Code] .....

Also why doesn't my background turn white??

Elevator Simulation In Event Time Not Clock

Apr 10, 2014

I am making a elevator simulator for my class. It needs to be "event time". I am having trouble understanding how I can make an "event time" simulator. Initially I was using a while loop to run a clock time simulation of x seconds for each event, until I ran into a concrete wall and had to call another method which took X seconds, while still needing to execute code.

An example of what I did is:

Spawn person -> person.goToElevator (Takes x seconds) - > person.waitForElevator (Until elevator arrives, x seconds). While this is happening, I needed to create another person and do the same thing, this will add another to the queue if the first person is still waiting. Etc etc, you get the point.

We have not learnt about multi threading, that is the next assignment.

Here is a quote from my lecturer:

"That's right, it requires multi-threading which we're not doing in this paper. Here's a solution that can work:

The person waiting for the lift and then doing lots of other things should do all that in a fraction of a second. So, you don't let the person really wait. Instead, you will set a timestamp in the future in the person object that "he's busy till that time". In all other steps in your simulation you will first check if a person is "busy" (i.e. has a timestamp in the future). If so, you can't use this object, otherwise, you can.

How does it create a bigger queue? Outputs I would have in my final simulation would be, averageQueueLength, numOfPeopleInBuilding etc.

Create 2D Game That Has Realistic Space Simulation

Jul 31, 2014

I am attempting to create a 2d game that has a realistic space simulation. The map is supposed to be set so that you are looking from the top down. The problem I am having exists in my interaction between the sun and a planet. Simply put, the planet will only move in a single diagonal direction without ever changing direction. The formulas I am using are F=(G*M1*M2)/D^2 and A=F/M. The code below is simplified.

(inside planet Class)
double x;
double y;
double mass;
double xForce;
double yForce;
double xAccel;
double yAccel;

[Code] ....

Things I have already tried:
1. Setting G to negative
2. changing the order of the subtraction in determining D
3. some weird pythagorean theorem thing someone suggested

FIFO Queue - Waiting Line Simulation

Jan 22, 2015

how to setup a program that simulates the progression of a line over time.The scenario involves a bank and 5 tellers. There is one line of customers that starts off with an initial length of 20. Every minute, 10 more customers are added to the line. As this is meant to be a FIFO queue the first 11 customers in the line will be distrusted among the 5 bank tellers as follows: Teller #1 will process 1 customer per minute, Teller #2 and #3 can each process 2 customers per minute, and Teller #4 and #5 can each process 3 customers per minute. Therefore, the first 11 customers in line will be processed within the first minute of the programs execution.

Unfortunately, I am not sure how to attack this thing. I am thinking that I need to setup a queue for the initial 20 customers and an array for the 10 customers that will be joining the line every minute. However, I am not sure how I can set this up to work automatically.

Simulation On Assembly Code Level By Writing A Mini-compiler

Sep 28, 2014

I need to do a simulation on the assembly code level by writing a mini-compiler for each ISA, i.e., 4, 3, 2-Address Architecture, Accumulator Architecture, Stack Architecture, and Load-Store Architecture.The input to the simulator is a segment of C program:The basic sample segments of C code are:

1. A = (B + C) * D - E;

2. F = (G + H) - (I + J);

3. G = H + A[I];

4. If (I == J) F = G + H;

Else F = G - H;

5. Loop: G = G + A[I];

I = I + J;

If (I != H) Goto Loop;

6. If (G < H) Goto Less;

7. While (save[I] == K)

I = I + J;

N-body Simulation - Forces For Body Not Calculating In Some Instances?

Mar 13, 2015

I am making a n-body simulation. For some reason, when I have two bodies orbiting each other and I add a third body, the two initial bodies stop orbiting each other.

EXAMPLE:

[URL]- earth is orbiting the sun, when I add mars,[URL] earth AND mars does not orbit the sun and both travel in a straight line. Almost as the forces are not being computed at all on the body. How can this be?

Here is the relevant code:
 
public void update(float deltaTime){
for(int i=0; i<bodies.size();i++){
resetForces(); 
bodies.get(i).update((float)(deltaTime / Math.pow(10,9))*timeScale);
lastTime = System.nanoTime();
//sets the forces for all bodies
for(int n=0; n<bodies.size();n++){

Writing A Method That Returns Words Without Four Letters Back To Main Method

May 27, 2014

I have to write a method called censor that gets an array of strings from the user as an argument and then returns an array of strings that contains all of the original strings in the same order except those with length of 4. For example if cat, dog, moose, lazy, with was entered, then it would return the exact same thing except for the words with and lazy.

Currently, my code so far just prints [Ljava.lang.String;@38cfdf and im stuck.

import java.util.Scanner;
 public class censorProgram {
public static void main (String args[]){
Scanner input = new Scanner (System.in);
System.out.println ("How many words would you like to enter?");
int lineOfText = input.nextInt();

Altering Parent Method Behavior By Overriding Method It Calls

Apr 21, 2014

I have two classes (Daughter and Son) that contain some very similar method definitions:

public class Family {
public static void main(String[] args) {
Daughter d = new Daughter();
Son s = new Son();
d.speak();
s.speak();

[Code] .....

Each of those classes has a "speak" method with two out of three lines being identical. I could move those into a parent class, but I need each of the child classes to continue to exhibit its unique behavior. I'm trying the approach below, which replaces the unique code with a call to a "placeholder" method that must be implemented by each child class:

public class Family {
public static void main(String[] args) {
Daughter d = new Daughter();
Son s = new Son();

[Code] .....

This works and moves the shared code from two places (the Daughter and Son classes) into one place (the new Mother class, which is now a parent class of Daughter and Son). Something about this feels a bit odd to me, though. It's one thing for a child class to override a parent class's methods to extend or alter their behavior. But, here, I've implemented an abstract method in the parent class to alter what happens when the parent class's method (speak(), in this case) is called, without overriding that parent class method itself.
