How To Get Sound To Import It To Game
Apr 7, 2015
how to make a simple game. I am having trouble when it comes to adding sound though. It tells me to do this:
package net.game.Game;
import java.applet.Applet;
import java.applet.AudioClip;
public class Sound {
public static final AudioClip BALL = Applet.newAudioClip(Sound.class.getResource("ball.wav"));
public static final AudioClip GAMEOVER = Applet.newAudioClip(Sound.class.getResource("gameover.wav"));
public static final AudioClip BACK = Applet.newAudioClip(Sound.class.getResource("back.wav"));
}
What this does is it gets the sound file then gives it a name(BALL=ball.wav GAMEOVER=gameover.wav ect..) and then there is other code in other classes that call the sound so it will run but it keeps giving me an error and I don't know what to do. How can I get it to import the sound? Here is the error.
PHP Code:
Exception in thread "main" java.lang.ExceptionInInitializerError
at net.game.Game.stuff.<init>(stuff.java:35)
at net.game.Game.stuff.main(stuff.java:62)
Caused by: java.lang.NullPointerException

I am making a game with java in a program called greenfoot.My problem is that a sound won't play when the player dies and a Game Over screen pops up..
- I have saved the audio file in my sound map of the scenario
- Applied the good name of the file
- tested the sound effect and it's working
this is my code:
public GameOver()
{
setImage(new GreenfootImage("GAME OVER", 100, Color.BLACK, null));
Greenfoot.playSound("fail-trombone-03.wav");
Greenfoot.stop();
}

Usually, most of the time, I import the standard java stuff.But what happens when I find a code with a list of those com. imports:
import java.io.File;
import java.io.IOException;
import com.itseasy.rtf.RTFDocument;
import com.itseasy.rtf.text.Border;
import com.itseasy.rtf.text.Field;
Where are these imports and how do I "get" them?

import java.applet.AudioClip;
public class Sound {
private AudioClip clip;
//all sounds
public static final Sound ScoreSound = new Sound("/Score.wav");
public static final Sound BounceSound = new Sound("/Bounce.wav");

I have to write a program that asks the user to enter "air", "water", or "steel", and the distance that a sound wave will travel in the medium. The program should then display the amount of time it will take. The amount of time it takes sound to travel in air can be calculated as follows;
Time = Distance/1,100
The amount of time it takes sound to travel in water can be calculated with the following formula:
Time=Distance/4,900
The amount of time it takes sound to travel in steel can be calculated with the following formula:
Time=Distance/16400
Here is my code:
import java.lang.String;
/**
This program displays numbers padded with leading zeros.
*/
public class SpeedofSound {
public static void main(String[] args) {
double D; // declares this as double
D = keyboard.nextDouble();
const double A = 1100; // declares this as a constant
[Code] .....
The following is the error I'm getting:
----jGRASP exec: javac SpeedofSound.Java
error: Class names, 'SpeedofSound.Java', are only accepted if annotation processing is explicitly requested
1 error
----jGRASP wedge2: exit code for process is 1.
----jGRASP: operation complete.

Okay, so I'm looking for a way to synthesize sound, and from what I've found around the interwebs it seems amazingly complex. Is there really not a function like "sound(wavelength, time)"? Alternatively a way to use an integer array to determine the acoutstic pressure at a given time, or some other way to determine the pressure at a given time?

What I want to do is very clear, just play sound and pause it. The problem is that I can't pause the music. When I click the pause button music keeps playing .I have been working on for 2 hours. I can't find the mistake; what am I doing wrong?
public class MainC extends JFrame implements Runnable,ActionListener {
private JPanel contentPane;

AudioPlayer.player.start(audios);
} catch (Exception e) {

just wondering why it does load;
i do get the warning

I wrote the below program to set up and play the game breakout as an assignment for Stanford's CS106 programming class. I wrote it on my old mac running OSX 10.6.8, with the version of Eclipse JDK that works on that machine. When I tested it back on the mac, the program worked normally. But now I am using a Windows 8.1 computer with the corresponding version of eclipse, and when I test the program again, the sound effect I coded does not play. I get the following error message in console when the ball hits the paddle or brick, which previously caused the sound clip to play.
Exception in thread "Thread-4" java.lang.IllegalArgumentException: Requested value -120.0 smaller than allowable minimum value -80.0.

at acm.util.SoundPlayer.setLineVolume(SoundClip.java:909)
at acm.util.SoundPlayer.run(SoundClip.java:860)
at java.lang.Thread.run(Unknown Source)
why my code would request a value below the min. I am using the mediatools class that is part of the ACM libraries we are required to use for the class to play the sound in question, found here: URL....I went ahead and tested all parts of the program and the missing sound effect is the only problem. Here is my complete code:
package Breakout_package;
import acm.graphics.*;
import acm.program.*;
import acm.util.*;
import java.applet.*;
import java.awt.*;
import java.awt.event.*;

I haven't been able to find a cut and paste working example of how to receive MIDI data from a MIDI device, like my piano, and display something to System.out.There are all sorts of examples for synthesizers, sequencers and sending data to a MIDI device, but I have not been able to find a single example of how to receive MIDI data and just display a simple message.
I just need something simple that works to start playing with it, and understanding how it works. Having a working example would also support understanding the Sound API descriptions. They read like differential equations texts books to me, i.e. not clear at all.
I have a working example of how to poll all devices and getDevice.info, which is supposed to then be used to address a specific MIDI device.
I've also looked at a number of books, in the store and on line.I haven't seen a single example anywhere.the closest I found to working examples was on StackOverflow, but I didn't understand some of the other code in the examples, which may or may not have been working correctly anyway.

Trying to find a way to use primitive data types to overload sound()method. I can't seem to warp my head around using an int or a double to overload the method. And if I did, how do you call them in the main afterwards?

I am quite new to developing Applets in java. I recently made an applet that will play a particular sound whenever a button is pressed. The sound files are placed in the same directory as the applet class file and i access them by using
AudioClip clip=getAudioClip(getCodeBase(),"A.wav").
The Applet runs fine in the appletviewer but whenever I try to open it using any browser like Chrome,IE,Firefox the applet loads but sound isn't played. I checked the java console and it showed
"java.security.AccessControlException: access denied ".
My questions are:
1. How do I allow the applet to get access to those files?
2. When the Applet is running from the local file system why CAN NOT I access those resources via getCodeBase() ???
3. I googled and found that I can sign a JAR and that can have full access to the computer. But how do I create a JAR from an applet (which has no Main method) while it asks me to point to the main class in the manifest?

accdg to this: [URL]....
we can use EL expression as follows:
${pageContext.request.contextPath}
but there's no instructions as to how I will set its value.
And also, what would happen in case I refer 2 css files in my jsp and both defines the following:
CSS 1 :
body { background-color: #fdf5e6;
font-size: 810px;
}
CSS 2:

i am migrating my web application from Server1 (Tomcat 5 and Java 1.5) to Server2 (Tomcat 7 wand Java 1.6).
In my web application, I have multiple adapters (web clients) that are connecting to external web services, https interfaces, sftp servers etc.
In order to connect with all these external interfaces, i have installed multiple certificates in my JRE keystore on Server1.
Now since the application is going to be migrated to Server2, i need to know if there is any way I can import all the existing certificates from Server1 JRE to Server2 JRE?
Since the application has been running on Server1 for a long time, I am not sure, what exactly is a complete list of certificates that I need to install on my Server2 JRE.
So i am kind of looking how can i generate the keystore file with certificates from the existing server1 JRE and then import it into Server2 JRE.
Does this command provide a list of all the installed certificates on my Server1 JRE?
server1:/webdienste/java/jdk/xxx/current/jre/lib/security> sudo /webdienste/java/jdk/xxx/current/bin/keytool -list -v -keystore cacerts | grep Eigner
The other solution i can think of is to manually download/save all the certificates by opening all the URLs in the browser and then import the .pfx files through keytool into my Server2 JRE.

Opoly works this way: The board is a circular track of variable length (the user determines the length when the game app runs). There is only one player, who begins the game at position 0.
Thus, if the board length is 20, then the board locations start at position 0 and end at position 19. The player starts with a reward of 100, and the goal of the game is to reach or exceed reward value 1000. When this reward value is reached or exceeded, the game is over. When the game ends, your program should report the number of turns the player has taken, and the final reward amount attained.
In Opoly the game piece advances via a spinner - a device that takes on one of the values 1, 2, 3, 4, 5 at random, with each of the five spin values equally likely.
Although the board is circular, you should draw the state of the board as a single "line", using an 'o' to represent the current player position, and * represent all other positions. Thus if the board size is 10, then this board drawing:
**o******
means that the player is at location 2 on the board.
Here are the other Opoly game rules:
If your board piece lands on a board cell that is evenly divisible by 7, your reward doubles.
If you land on the final board cell, you must go back 3 spaces. Thus if the board size is 20, the last position is position 19, and if you land there, you should go back to position 16. (If the position of the last cell is evenly divisible by 7, no extra points are added, but if the new piece location, 3 places back, IS evenly divisible by 7, then extra points ARE added).
If you make it all the way around the board, you get 100 points. Note that if you land exactly on location 0, you first receive 100 extra points (for making it all the around), and then your score is doubled, since 0 is evenly divisible by 7,
Every tenth move (that is, every tenth spin of the spinner, move numbers 10,20,30,... etc.), reduces the reward by 50 points. This penalty is applied up front, as soon as the 10th or 20th or 30th move is made, even if other actions at that instant also apply. Notice that with this rule it's possible for the reward amount to become negative.
Here is the driver class for the game:
import java.util.*;
public class OpolyDriver{
public static void main(String[] args){
System.out.println("Enter an int > 3 - the size of the board");
Scanner s = new Scanner(System.in);
int boardSize = s.nextInt();
[Code] ....
heres the methods:
REQUIRED CODE STRUCTURE: Your Opoly class must include the following methods (in addition to the Opoly constructor) and must implement the method calls as specified:
playGame - The top-level method that controls the game. No return value, no parameters. Must call drawBoard, displayReport, spinAndMove, isGameOver.
spinAndMove - spins the spinner and then advances the piece according to the rules of the game. No return value, no parameters. Must call spin and move.
spin - generates an integer value from 1 to 5 at random- all equally likely. Returns an integer, no parameters.
move - advances the piece according to the rules of the game. No return value, takes an integer parameter that is a value from 1 to 5.
isGameOver - checks if game termination condition has been met. Returns true if game is over, false otherwise. No parameters.
drawBoard - draws the board using *'s and an o to mark the current board position. Following each board display you should also report the current reward. No return value, no parameters.
displayReport - reports the end of the game, and gives the number of rounds of play, and the final reward. No return value, no parameters.

Im trying to make a tic tac toe game that you play against the computer using a random number generator and two dimensional arrays for the game board. Im not trying to make a GUI, the assignment is to have the board in the console, which I have done. I have run into a few problems with trying to get the computer player to correctly generate 2 integers and have those two integers be a place on the game board. Here is my code so far.
import java.util.Random;
import java.util.Scanner;
public class TicTacToe {
private static Scanner keyboard = new Scanner(System.in);
private static char[][] board = new char[3][3];
public static int row, col;

I see you can import in 2 ways:
import java.util.*;
or
import java.util.Scanner/Random/etc;
if I used the first one it imports all the librarys within that (directory?). If so would that add to a bigger file size?

I'm making an import/export of xml - I have the import of xml sorted I'm just trying to finish off the export. My export class is called XmlWriter.java. Inside the class I have an updateFile method to update an xml file as such:
public void updateFile(Environment environment,Document doc)
{
// code
}
I then in my main method have
public static void main(String argv[]){
//declare new object of class
XmlWriter xmlWriter = new XmlWriter();
//test testUpdate method
// xmlWriter.testUpdate();
Environment environment = ;
[code]....
I don't know what to make my variables equal to - eclipse keeps trying to use null but obviously that won't work. The Environment is another class that just contains getters and setters for the 3 different databases (that are in the xml file) and the getter/setter for the environment ID (also in xml file).

How to use a .class file I unpacked from a .jar file I downloaded from the Internet.
I downloaded the commons-io-2.4.jar file from commons . apache . org /proper/commons-io/
In it you can see that there is a class called FileUtil.class:
jar tf commons-io-2.4.jar | grep FileUtil
org/apache/commons/io/FileUtils.class
I extracted this with the following command:
jar xf commons-io-2.4.jar FileUtils.class
It is now in ..uk/ac/ebi/bioinvindex/services/datasearch/commons/FileUtils.class
Now, I have a java file where I would like to use FileUtils.
How do I do that? How do I import it?

I am still playing around with decks of cards, and am now trying to implement some visualizations using Applets.
Here is how I enter my deck of cards into an array list: this works just fine:
String[] Suits = new String[]{"S","H","D","C"};
String[] Values = new String[]{"A","2","3","4","5","6","7","8","9","10","J","Q","K"};
ArrayList<String> deck = new ArrayList<String>();
for(String suit : Suits) {
for(String value : Values) {
deck.add(suit+"_"+value);
}
}
The end result of this is an array 'deck' which contains a string representing each of the 52 playing cards. Great.
Now I would also like to use some pictures for future implementations I am working on. I have 52 images (.png, though I doubt it matters) stored in the right place. They are named as "H_5.png", and "S_A.png", for example, just as I named the cards in the previous array. I would like to do something as follows
ArrayList<Image> deckpic = new ArrayList<Image>();
for(String suit : Suits) {
for(String value : Values) {
deckpic.add(getImage(suit+"_"+value+".png"));
}
}
Now of course this doesn't work. The line
suit+"_"+value+".png"
is a string, not the name of a file. How I have previously loaded images is to use something like this:
the_pic = getImage("picture_of_pony.jpg");
but of course I can't use the quotations in my card loop, since I want "suit" and "value" to range and not just be the strings suit and value.

I have the following data in a file called books.xml in my WEB-INF folder:
<?xml version="1.0"?>
<books>
<book>
<name>Padam History</name>
[Code] ....
I'm using the following code in a jsp:
<c:import var="bookInfo" url="/WEB-INF/books.xml" />
I know that it's finding the file because if I delete books.xml from the WEB-INF folder I get a FileNotFound exception.
However, for some reason it doesn't appear to be importing the data into the bookInfo variable.
I noticed this problem because when I try to parse it via:
<x:parse xml="${bookInfo}" var="output"/>
I get org.xml.sax.SAXParseException: Premature end of file.
When I try to display the data in the variable either by:
<c:out value="${bookInfo}" />
...or by means of a scriptlet (which I realize is not a best practice):
<%
String myVariable = (String)pageContext.getAttribute("bookInfo");
System.out.print("bookInfo=" + myVariable);
%>
...I get nothing.
BTW when I do:
<c:import var="data" url="http://www.tutorialspoint.com"/>
<c:out value="${data}"/>
that works fine!
