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 java.awt.*;
import hsa.*;
import java.util.Random;
public class SlotGraphics
{
Console c;
int x = 200;
int y = -100;
[code]....

I have an image that moves with arrow keys, and I want to make it appear to be moving. So, I made that image, and then another with the legs moved, to give the illusion of motion. I added it to an event
Java Code:
if (k == KeyEvent.VK_RIGHT) {
image1 = image6;
peterx = peterx + 10;
resetIt();
repaint();
} mh_sh_highlight_all('java');
But it only serves to change it once. How would I make it revert to the original frame once it is converted to the second frame (image 6)? I tried a gif but to no avail?

The oint is to make an animation using Timer with various frames - So that's my code, but when I define the sider class, I keep getting cannot find symbol errors! I don't know what to do! Is it the change listener? My teacher never really taught us how to do it apart from Actionlistener. He said we might have to put it within an ActionListener?

I want to be able to show a set of pictures that would result in a primitive sort of animation. I'd like to do something lighter than making my thread sleep. Is there a way to pause the code without pausing the thread, other than something like a for-next loop of 1 to 2000 just to take up time?

I have a JTable with 6 rows and 6 columns, i.e. 36 cells. I have 1 image-icons.. I want an animation of the image, it should just be shown in the JTable as described below.
In my following explananation: Cell[row;column]
State 1
Cell[0;0] = 1st image
Cell[remain] = empty
PAUSE
State 2
Cell[0;0] = empty
Cell[0;1] = 1st image
Cell[remain] = empty
PAUSE
State 3
Cell[0;0] = empty
Cell[0;1] = empty
Cell[0;2] = 1st image
Cell[remain] = empty
PAUSE
and so on,
Once the image hits last column, it jumps 2n row 1st cell so the animation is like a snake move of the image.
I currently got stuck loading the image 1 after another, so "transition from state_i to state_i+1"
I got confused using Thread. How can I have pause between those states (I described above).
I use the Threads somehow wrong. Any example loading images in Cells (JTable) with pause in between?

I am wondering why in the example below the opacity is interpolated from the start value to the specified keyframe value but the width is not. It just jumps to the keyframe value right on button click.
import javafx.animation.KeyFrame;
import javafx.animation.KeyValue;
import javafx.animation.Timeline;
import javafx.application.Application;

import javafx.geometry.Pos;

I'm trying to get my animation for my java game to move along the edges of my device. Once it hits the edge I would like it to turn and keep moving along the edges. I'm sure this is easier than I'm making it but I can't find much on this. Right now my animation moves right and goes right off the screen until the app is closed and restarted.
This is my code so far:
package com.pjf.animation;
import java.io.IOException;
import java.io.InputStream;
import android.content.Context;
import android.content.res.AssetManager;
import android.graphics.Bitmap;
[Code] .....

I am looking for a way to find a resize animation for an application I'm developing. I found this answer but I figure there could be a better method out there,
Java - How do I create a Resize animation for JavaFX stage? - Stack Overflow
I am just looking to select something in a list, then press a button which would enable the animation and enlarge the stage. This will happen twice.

I have a problem with this ascii animation program I am working on. I declared a method inside of my class AsciiAnimation extends JFrame implements ActionListener, called
package AsciiAnimation;
import java.awt.*;
import java.awt.event.*;
import java.util.ArrayList;
import javax.swing.*;
public class AsciiAnimation extends JFrame implements ActionListener{
int currentFrame = 0;
ArrayList<String> frameList = new ArrayList<String>();
[Code] ....
Basically I just am trying to figure out how java works with me accessing those 2 data members, currentFrame and frameList inside of my first class ALL in the same package.

In the code that I am currently trying to do, I want to make it so that the program loops until the randomly generated number is 1, to a maximum of 4 loops.I have figured out how to make it stop at a randomly generated 1, but I can't quite figure out how to make it stop at four loops if it doesn't reach the 1 before the maximum number of loops.

how many integers the user wants to use. The user will enter for example a 4. The user inputs a 2, 4, 6, and 10. So then we get our outputs...Then the code will ask if you want to run this program again. My question is, if the user inputs a -1 for example 2, 4, 6, -1....the code will not continue. I wanted to use a while loop, such as while (scores != -1) but it doesn't work.
Enter the amount of integers you want to use4
Intenger # 1 2
Intenger # 2 4
Intenger # 3 6
Intenger # 4 10
You entered 2.0 4.0 6.0 10.0
Average = 5.5
Variance = 8.75
Standard Deviation = 2.96
Do you have another set of numbers?

I am making a project that should play, stop, and loop three different songs (not at the same time). I am calling this SoundPlayer class from my main class:
import javax.sound.sampled.*;
import java.util.*;
public class SoundPlayer {
List<AudioInputStream> songs = new ArrayList<AudioInputStream>();
int currentSong, currentPlayType;
[Code] ....
When my class calls setPlayType(2), which should make it play, I get the following runtime error:
java.lang.NullPointerException
at SoundPlayer.playSong(SoundPlayer.java:32)
at SoundPlayer.setPlayType(SoundPlayer.java:64)
at MainPanel$AListener.actionPerformed(MainPanel.java:60)
(...)
Line 32 is if(clip.isOpen()), but I'm pretty sure I instantiated clip properly in the constructor.

What I mean is, I have this set and it is supposed to take out all the duplicates. If I enter aaabbbcccd the output should be abcd, but instead my code just outputs the last word, or in this case letter entered.

public class setdemo

public static void main(String[] args)

I am making a WebCrawler, and I am trying to work out a way to stop duplicate links from getting put in however ArrayList.contains() doesnt seem to be working for me can someone look at my code and see if I am doing something wrong? I have also tried variations of it such as
!link.contains(newLink)
and
!link.contains(newLink.getLinkUrl())
with no luck. The Problem area is
for(Element lnks: link){
linkSrc = lnks.absUrl("href");
WebPage newLink = new WebPage(linkSrc);
if(!link.contains(linkSrc)){
links.add(newLink);

I have a Stream instace which produces values using an infinite Supplier (it supplies values taken from an electronic sensor -- so unless the battery is low, the sensor will provide "for ever").
The stream is processed by a Collector using Stream.collect() (e. g. imagine that the values from the sensor should be averaged; in fact what it does is a bit more compliacted maths).
The problem is that the collector does not produce a result but hangs up, as the supplier does never stop providing more sensor values.
So what I need is a limitation rule that stops the stream. While there is a Stream.limit(long) method, it actually does not solve my problem as in my case it is not practical to stop after a particular count, while I actually want to stop streaming when the sensor value exceeds a particular limit etc. (hence, voids an arbitrary rule).
To sum up, what I need is Stream.limit(Predicate), i. e. the stream will stopped once the predicate becomes true.
Unfortunately I did not find anything like that in JRE 8.
Is that planned for JRE 8.1 or JRE 9.0? Or is there a known (and sophisticated) workaround?

"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?

Inside a While Loop (While Loop begins if a condition is True) I have an If Statement, the else part of the statement assigns False to the condition I mentioned earlier.
But I've tried de-bugging and even when the code goes through the else part of the statement, firstly it returns False but then it returns to the beginning of the loop as True again.

I am trying to make a stopwatch using the timer class and JButtons. When I run my program and I hit start the time stays at zero. What I want my stopwatch to do is when I press start it shows the number of seconds that have passed. The start button will then become disabled and the stop button will be the only button able to be pressed. When you hit stop it should enable only the start and restart buttons. Here is my code.
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
public class StopWatchPanel extends JPanel
{private final int DELAY = 1000;

Let's say we have a matrics of coordinates:
(0,0) (0,10) (0,20)
(10,0) (10,10) (10,20)
(20,0) (20,10) (20,20)
And we have a class that draws a rectangle of 10 pixel height and 10 pixel width at 0,0 coordinates.
And we want to move with the arrows the rectangle but not to go off the frame.
The question is:
How can I do that if I draw another rectangle, it knows where is the other object and they not collapse. And so on, they move, but not collapse, just touch and stop.

I have a servlet which sends HTML5 server sent events to the jsp client. The servlet sends data to the client every one second. The jsp client instantiates a new eventsource and recieves the data. When the window is about to close, the jsp client closes eventsource at the "beforeunload" event (shown in the code below).
However, I have noticed that even after the client closes the eventsource and the browser exits, the server continues sending data. As far as the documentation on eventsource goes, using eventsource.close() is enough to stop client from reconnecting to the server and the server will stop sending any further push notifications.
Why the server does not stop sending push notifications even after eventsource.close() and the browser exit? Do I write any other piece of code to notify the server to stop sending data once client exits?
Pasted below are the servlet (server ) code and the client code.
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;

I've got my clear button to work on most of the stuff I want, however I cant figure out how to fix the price to stop adding up. e.g. hit a button image with a price of 599.99, hit the clear button to empty, select price of 599.99 again then it display 1199.98.
sofa method
if (source == jBSofa) {
System.out.println("Sofa"); {
dTotal = dTotal + 599.99;
jTotal.setText(Double.toString(dTotal));
jTotal.setText(String.format("%.2f", dTotal));
}
Reset method
private void Reset() {
jTTotal.setText(" ");
jTotal.setText(" "); //sub total clear
jTTotalTotal.setText(" ");
