Java: Console stops working when using javazoom

When I start playing music by javazoom library, console stops answer. I can write anything, but no response.
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.util.Scanner;
import javazoom.jl.decoder.JavaLayerException;
import javazoom.jl.player.advanced.AdvancedPlayer;
public class Main {
public static void men(int i) {
try {
FileInputStream fis = new FileInputStream("Filename.WAV");
AdvancedPlayer player = new AdvancedPlayer(fis);
player.play();
}catch(FileNotFoundException e){
e.printStackTrace();
}catch(JavaLayerException e) {
e.printStackTrace();
}
}
public static Scanner scn = new Scanner(System.in);
public static void main(String[] args) {
while(true) {
int i = scn.nextInt();
if(i == 1) {
men(i);
}
if(i == 5) {
System.out.println("i am here");
}
}
}
}
Is there solution? Or javazoom can't play audio and do other things?

I'm not clear what you mean by "console stops answer" and "Javazoom can't play audio and do other things."
You can execute the javazoom play command in its own thread. While that thread runs concurrently, your program will be free to execute other tasks.
Do you know how to create and launch a thread? Here is Oracle's tutorial Processes and Threads.

UnsupportedAudioFileException with a .wav file

I'm trying to load a .wav file in my EnviromentAudio object, but I received only an UnsupportedAudioFileException and I don't know why. Because the file is a wav and I've tried to encode it as an unsigned 8 bit, as a signed 16 bit, with a 44100 bit rate, as a GSM, as a A-law... long story short I've tried a lot of encoding, as many people suggested, but no one worked. Probably I'm not getting something, so, I want to ask what I'm doing wrong.
EDIT:
As pointed out I should have specified some things: first of all, to set some context, I am using Java 8 to create a little pc game for a project, which must uses the basics components of java. Said that, I'm using the ClassLoader
, because I have a mess in the project folder. It does not follow the convention and I have to keep like that. It's structured like this:
-src
-app
-audio
EnviromentAudio.java // Class that need to load soundtrack.wav
-res
-audio
Soundtrack.wav // Audio to be loaded
And I know that a getResource.. should start always with a /, but if I add that slash, then every attempt to get a resource results in a NPE. Probably that's caused by the folders disposition and, by the way, the resources folder is set as source folder, so I'm not even quite sure about that, cause, also, I've already used the getResource to get other files without problems.
In this case The getResource works fine, that is it retrieves the file, but the AudioSystem generates an error. I've tried to isolate the parties involved, but the only problem seems to be here. I'm adding the AudioManager class, the Audio class inherited by EnviromentAudio, and the whole EnviromentAudio, with the hope that it will be of help for a better understanding. I also provided a main in the AudioManager class, which should be enough to replicate the error.
Audio class:
package application.core.audio;

This is more to help with troubleshooting than a solution (expanding on Andrew Thompson's suggestion of making an MRE. Are you using a particular framework? Or is it something of your own making? For a second I though it might be Android (due to presence of AudioManager).
Following is a more minimal example for play testing your .wav file. Put the wav file in the same folder as this class. Does your .wav file play when using this?
import java.io.IOException;
import java.net.URL;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.UnsupportedAudioFileException;
public class BasicClipExample {
public static void main(String[] args) {
try {
BasicClipExample.run();
} catch (UnsupportedAudioFileException | IOException
| LineUnavailableException | InterruptedException e) {
e.printStackTrace();
}
}
private static void run() throws UnsupportedAudioFileException,
IOException, LineUnavailableException, InterruptedException
{
String filename = "yourSound.wav";
URL url = BasicClipExample.class.getResource(filename);
AudioInputStream ais = AudioSystem.getAudioInputStream(url);
DataLine.Info info = new DataLine.Info(Clip.class, ais.getFormat());
Clip clip = (Clip) AudioSystem.getLine(info);
clip.open(ais);
clip.start();
Thread.sleep(6000); // plays up to 6 seconds of sound before exiting
clip.close();
}
}
If it works, then something is odd about your framing code. From here you can progressively check if things like the file separator logic are working. You can also add some lines to print out the AudioFormat if the file loads.
Another way I sometimes inspect files is to load them into Audacity, which is free. Info about the file format is pretty easy to inspect with that tool. If I had to wager, and the issue IS the .wav format, I'm guessing that the file is recorded at a higher quality level than Java is set to work with, e.g., 48000 (maybe Java supports?) or 96000 fps or 24- or 32-bit encoding rather than 16-bit.

I want to read the output from the console

After a long period of searching for my problem, I have no other idea, I have to ask here.
I search for a method to read the console output or System.out to a JavaFX TextArea but I don't know how I get those strings.
I want to put that into an external Thread:
package Threads;
import Core.Engine;
import java.io.ByteArrayOutputStream;
import java.io.PrintStream;
import java.util.Scanner;
public class ConsoleListenerThread implements Runnable {
Engine engine;
public ConsoleListenerThread(Engine engine) {
this.engine = engine;
}
#Override
public void run() {
String line;
while (true){
}
}
}
Update:
I really need the console output...what you see when you start a program. And how I get there is unnecessary I think (Startup etx), because I just want a String whenever the console prints a new output.
Example:
System.out.println("Hello");
And then my thread revive this string:
"hello"

If you are printing directly to the console with the System.out.println() method, then you already have the string. If , on the other hand, you are calling a different method that prints to the console from another object, try having that method return a String instead so that you can store that data.

So I solved this problem, so here is the code:
package Threads;
import Core.Engine;
import java.io.*;
public class ConsolListenerThrad implements Runnable {
Engine engine;
public ConsolListenerThrad(Engine engine) {
this.engine = engine;
}
#Override
public void run() {
String line = null;
PipedOutputStream pOut = new PipedOutputStream();
System.setOut(new PrintStream(pOut));
PipedInputStream pIn = null;
try {
pIn = new PipedInputStream(pOut);
} catch (IOException e) {
e.printStackTrace();
}
BufferedReader reader = new BufferedReader(new InputStreamReader(pIn));
while (true){
try {
line = reader.readLine();
} catch (IOException e) {
e.printStackTrace();
}
engine.printConsollogOnGui(line);
}
}
}

Java clipboard as stack in paste override

I have done my research, no useful results found.
Here is the deal, I'm writing a 'new' clipboard that works like a stack instead of a 'area'. And I'm brave or stupid enoght to do that in Java. So far in my tests to see if this is possible I have managed to create this stack behavior. The only problem I'm getting is that sometimes, mainly when I paste the top of the stack (pop operation), it doesn't pop or for some other reason it pastes twice.
Example:
If i copy this three words: Carlos, Lucas, Eastwood
The stack clipboard behaves like this at paste: Eastwood, Eastwood, Lucas, Carlos
I'm using JNativeHooks for reading the system keypresses and determining when the user is pasting.
I think what is happening is that the system is pasting before my code... Well, here is the code anyway (It is a test, that explains why it is badly commented):
import java.awt.Toolkit;
import java.awt.datatransfer.Clipboard;
import java.awt.datatransfer.Transferable;
import java.util.Stack;
import org.jnativehook.GlobalScreen;
import org.jnativehook.NativeHookException;
import org.jnativehook.NativeInputEvent;
import org.jnativehook.keyboard.NativeKeyEvent;
import org.jnativehook.keyboard.NativeKeyListener;
public class Test3 implements NativeKeyListener {
Clipboard sysClip = Toolkit.getDefaultToolkit().getSystemClipboard();
Stack<Transferable> clipStack = new Stack<>();
public static void main(String[] args) {
try {
GlobalScreen.registerNativeHook();
} catch (NativeHookException ex) {
System.err
.println("There was a problem registering the native hook.");
System.err.println(ex.getMessage());
System.exit(1);
}
Test2 t2 = new Test2();
// Construct the example object and initialze native hook.
GlobalScreen.getInstance().addNativeKeyListener(t2);
}
#Override
public void nativeKeyPressed(NativeKeyEvent ev) {
// Copy
if (ev.getKeyCode() == NativeKeyEvent.VK_C
&& NativeInputEvent.getModifiersText(ev.getModifiers()).equals(
"Ctrl")) {
// Clip the pop
try {
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
clipStack.push(sysClip.getContents(null));
System.out.println("Ctrl+C : Stack(" + clipStack.size() + ")");
}
// Paste
if (ev.getKeyCode() == NativeKeyEvent.VK_V
&& NativeInputEvent.getModifiersText(ev.getModifiers()).equals(
"Ctrl")) {
// Clip the pop
try {
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
if (clipStack.size() > 1) {
sysClip.setContents(clipStack.pop(), null);
} else
sysClip.setContents(clipStack.peek(), null);
System.out.println("Ctrl+V : Stack(" + clipStack.size() + ")");
}
}
#Override
public void nativeKeyReleased(NativeKeyEvent e) {
}
#Override
public void nativeKeyTyped(NativeKeyEvent e) {
}
}

I would think the same as you suggested.
Have a copy and paste key combination something different from ctrl+c and ctrl+v and you can even bypass using the system clipboard. Simply push the selected text and pop the text directly to your text pointer in your application provided of course that you are using this stack behavior for only a particular application.
The system retains it's own copy of latest clip and it gets a duplicate from your sysClip.setContents(clipStack.pop(), null) on paste operation.
I don't have much idea on disabling the system behavior. You can do research on that. But you can always make sure that it's the only problem by changing the key combination.

HtmlUnit WebClient Timeout

In my previous questions about HtmlUnit
Skip particular Javascript execution in HTML unit
and
Fetch Page source using HtmlUnit : URL got stuck
I had mentioned that URL is getting stuck. I also found out that it is getting stuck due to one of the methods(parse) in HtmlUnit library is not coming out of execution.
I did further work on this. I wrote code to get out of the method if it takes more than specified time-out seconds to complete.

}

} catch (Exception e) {

//InterruptedException: the executor thread was interrupted
//interrupts the worker thread if necessary

//logger.warn("encountered problem while doing some work", e);
throw new TimeoutException();
}finally{
executor.shutdownNow();
}
}
public static void getPageSource(String productPageUrl)
{
try {
if(productPageUrl == null)
{
productPageUrl = "http://ericaweiner.com/collections/";
}
WebClient wb = new WebClient(BrowserVersion.FIREFOX_3_6);
wb.getOptions().setTimeout(120000);

This code does come out of doWorkWithTimeout(url, 60); method. But this does not terminate.
When I try to call similiar implementation with following code:
import java.util.Date;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.Future;
import java.util.concurrent.TimeUnit;
import org.apache.log4j.Logger;

public void doWork() throws InterruptedException {
logger.info(new Date()+ "Starting worker method ");
Thread.sleep(20000);
logger.info(new Date()+ "Ending worker method ");
//perform some long running task here...
}
public void doWorkWithTimeout(int timeoutSecs) {
//maintains a thread for executing the doWork method
ExecutorService executor = Executors.newFixedThreadPool(1);
logger.info("Starting method with "+timeoutSecs+" seconds as timeout");
//set the executor thread working
final Future<?> future = executor.submit(new Runnable() {
public void run()
{
try
{
doWork();
}
catch (Exception e)
{
throw new RuntimeException(e);
}
}
});
//check the outcome of the executor thread and limit the time allowed for it to complete
try {
future.get(timeoutSecs, TimeUnit.SECONDS);
} catch (Exception e) {
//ExecutionException: deliverer threw exception
//TimeoutException: didn't complete within downloadTimeoutSecs
//InterruptedException: the executor thread was interrupted
//interrupts the worker thread if necessary
future.cancel(true);
logger.warn("encountered problem while doing some work", e);
}
executor.shutdown();
}
public static void main(String a[])
{
HandleScraperTimeOut hcto = new HandleScraperTimeOut ();
hcto.doWorkWithTimeout(30);
}
}
If anybody can have a look and tell me what is the issue, it will be really helpful.
For more details about issue, you can look into Skip particular Javascript execution in HTML unit
and
Fetch Page source using HtmlUnit : URL got stuck
Update 1
Strange thing is : future.cancel(true); is returning TRUE in both cases.
How I expected it to be was :
With HtmlUnit it should return FALSE since process is still hanging.
With normal Thread.sleep(); it should return TRUE since the process
got cancelled successfully.
Update 2
It only hangs with http://ericaweiner.com/collections/ URL. If I give any other URL i.e. http://www.google.com , http://www.yahoo.com , It does not hand. In these cases it throws IntruptedException and come out of the Process.
It seems that http://ericaweiner.com/collections/ page source has certain elements which are causing problems.

Future.cancel(boolean) returns:
false if the task could not be cancelled, typically because it has already completed normally
true otherwise
Cancelled means means the thread did not finish before cancel, the canceled flag was set to true and if requested the thread was interrupted.
Interrupt the thread menans it called Thread.interrupt and nothing more. Future.cancel(boolean) does not check if the thread actually stopped.
So it is right that cancel return true on that cases.
Interrupting a thread means it should stop as soon as possible but it is not enforced. You can try to make it stop/fail closing a resource it needs or something. I usually do that with a thread reading (waiting incoming data) from a socket. I close the socket so it stops waiting.
