changing midi volume in java

first of all changing volume is working but i got some problems while changing the volume so 1) after changing the volume like setting it to 0 (no volume) you still hearing parts of the song in the default value of the volume 2)after song changed the volume getting back to the default value of the volume
public static void setVolume(double value) {
System.out.println();
int CHANGE_VOLUME = 7;
midivol =(value);
try {
if (synthesizer.getDefaultSoundbank() == null) {
System.out.println(444);
ShortMessage volumeMessage = new ShortMessage();
for (int i = 0; i < 16; i++) {
volumeMessage.setMessage(ShortMessage.CONTROL_CHANGE, i, CHANGE_VOLUME,(int)(value * 127.0));
volumeMessage.setMessage(ShortMessage.CONTROL_CHANGE, i, 39, (int)(value * 127.0));
MidiSystem.getReceiver().send(volumeMessage, -1);
}
} else {
MidiChannel[] channels = synthesizer.getChannels();
for( int c = 0; c < channels.length; c++ ) {
if(channels[c] != null) channels[c].controlChange( 7, (int)( value*127.0) );
}
}
music.setSequence(sequence);
} catch (Exception e) {
e.printStackTrace();
}
}
playing midi:

System.err.println("Problem loading MIDI file.");

}
MidiChannel[] channels = synthesizer.getChannels();
for (int i = 0; i < channels.length; i++) {

}

volumeMessage.setMessage(ShortMessage.CONTROL_CHANGE, i, CHANGE_VOLUME,(int)(value * 127.0));
volumeMessage.setMessage(ShortMessage.CONTROL_CHANGE, i, 39, (int)(value * 127.0));
MidiSystem.getReceiver().send(volumeMessage, -1);
This code sends one message. The contents of that message are the values set by the second setMessage call, so the volume MSB is not changed at all.
(And this is the wrong way of computing the LSB.)
Controller 7 is indeed for volume, but there is no exact standard for how the values are to be interpreted. Apparently, your synthesizer does not mute itself when it receives a volume of zero.
Many MIDI files do their own changes to controller 7. If your synthesizer supports Master Volume, you should send that instead.

How to fix input getting cut off by output

So, I'm trying to create a function (If not pretty) IRC client using no libraries, written in Java. I've gotten almost everything working, the only problem is that I'm currently getting user input using System.in. And if someone else in the channel sends a message while I'm in the middle of typing, it cuts off what I currently have, and I need to guess where I am in the string. I want to know if there's a way to separate user input from the output of the program, so that this doesn't happen. This is the code in question:
new Thread(() -> {
while(connected[0]) {
String output = sc.nextLine();
if(!output.startsWith("~") && !output.startsWith("/")) {
try {
writeToSocket("PRIVMSG " + focused[0] + " " + output);
} catch (IOException e) {
e.printStackTrace();
}
}
if(output.substring(1).toLowerCase().startsWith("quit")) {
String[] split = output.substring(5).split(" ");
StringBuilder sb = new StringBuilder();
for (int i = 0; i < split.length; i++) {
if(i == 0) {
sb.append(split[i]);
}
sb.append(" ").append(split[i]);
}
try {
writeToSocket("QUIT " + sb.toString());
connected[0] = false;
} catch (IOException e) {
e.printStackTrace();
}
}else if(output.substring(1).toLowerCase().startsWith("focus")) {
String get = output.substring(7);
if(!channels.contains(get)) {
print("Not connected to channel");
}else {
try {
writeToSocket("PART " + focused[0]);
writeToSocket("JOIN " + get);
} catch (IOException e) {
e.printStackTrace();
}
focused[0] = get;
}
}else if(output.substring(1).toLowerCase().startsWith("join")) {
String get = output.substring(6);
channels.add(get);
}
if(output.startsWith("/") && output.substring(1).toLowerCase().startsWith("msg")) {
String[] split = output.substring(5).split(" ");
String username = split[0];
StringBuilder msg = new StringBuilder();
for(int i = 1; i < split.length; i++) {
if(i == 1) {
msg.append(split[i]);
continue;
}
msg.append(" ").append(split[i]);
}
try {
writeToSocket("PRIVMSG " + username + " " + msg.toString());
} catch (IOException e) {
e.printStackTrace();
}
}
}
}).start();

Tapping android screen solves media skipping, how to fix?

I wrote an Android app that plays multi-track audio files and it works completely in the simulator. On the device, it plays for a few seconds and then starts skipping and popping every few seconds. If I continuously tap the screen in the dead space of the app, the skipping doesn't occur and then recurs about 5 seconds after screen tapping ceases. I presume that this has something to do with thread priority, but I log the thread priority in the play loop and it never changes.
I'm hoping that somebody can tell me either:
a hack where I can simulate a screen tap every second so that I can run a beta test without the app skipping
explain a way to debug activity/thread/etc priority when it seems that my thread priority isn't changing when it seems like it is.

Have you monitored the CPU frequency while your application is running? The CPU governor is probably scaling the CPU up on touch and scaling back down on a timer. Increasing the priority on your background thread to THREAD_PRIORITY_DEFAULT will probably fix the issue, the default priority for AsyncTask is quite low and not appropriate for Audio.
You could also increase the size of the AudioTrack's buffer to some multiple of the value returned by getMinBufferSize, that method only returns the minimum possible buffer for the Class to operate, it does not guarantee smooth playback.

java.io.StreamCorruptedException over sockets [duplicate]

This question already has an answer here:
StreamCorruptedException: invalid type code: AC
(1 answer)
Closed 5 years ago.
I am developing a multiplayer snake game. The game seems to be running fine except it often(not every time) randomly throws the java.io.StreamCorrupted Exception type code :AC
The full StackTrace of the same is given below.

while (true) {
boolean gameup = false;
objin = new ObjectInputStream(socket.getInputStream());
Object insnake = objin.readObject();
if (((Snake) insnake).player.length() >= 9) {

} else if (((Snake)insnake).player.substring(0, 10)

}
if (s.length == 4) {
System.out.println(s[3]);
if (s[3].equals("game_up")) {
gameup=true;
}
}
}
}
Snake temp = new Snake((Snake) insnake);
map.remove(temp.player);
map.put(temp.player, temp);

JOptionPane.showMessageDialog(null, "Server Closed", "ERROR",
JOptionPane.ERROR_MESSAGE);
System.exit(0);
} catch (Exception e) {
e.printStackTrace();
}
}
The corresponding server side code for the same is as follows:
void relay(Snake move) {
boolean foodeaten = false;
Snake snake = move;
try {
if (move != null && move.player.length() > 9) {
if (move.player.equals("food_eaten")) {
move.player = move.player + ","
+ (Snakeserver.randomGenerator.nextInt(100) * 6)
+ ","
+ (Snakeserver.randomGenerator.nextInt(100) * 6);
foodeaten = true;
snake = (Snake) objin.readObject();
int rows = Snakeserver.score.getModel().getRowCount();
int row = 1;
for (int i = 0; i < rows; i++) {
if (((Snake) snake).player
.equals((String) Snakeserver.score.getModel()
.getValueAt(i, 0))) {
row = i;
break;
}
}
if (snake.score >= 300)
move.player += "," + "game_up";
Snakeserver.score.getModel()
.setValueAt(snake.score, row, 1);
}
}
if (move.gameover) {
int rows = Snakeserver.score.getModel().getRowCount();
int row = 1;
for (int i = 0; i < rows; i++) {
if (snake.player.equals((String) Snakeserver.score
.getModel().getValueAt(i, 0))) {
row = i;
break;
}
}
Object temp = Snakeserver.score.getModel().getValueAt(row,
1);
temp += " GAME OVER";
Snakeserver.score.getModel().setValueAt(temp, row, 1);
}
for (Snake name : map.keySet()) {
if (name != null) {
if (name.player.equals(snake.player)) {
name.copyValues(snake);
}
objout = new ObjectOutputStream(map.get(name)
.getOutputStream());
objout.writeObject(move);
objout.flush();
if (foodeaten) {
objout = new ObjectOutputStream(map.get(name)
.getOutputStream());
objout.writeObject(snake);
objout.flush();
}
}
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Actually I don't know where the problem lies so I have perhaps dumped more code than necessary.

I finally found the solution to my problem after digging around for a few hours.
In the server side code see the following piece of code:
for (Snake name : map.keySet()) {
if (name != null) {
if (name.player.equals(snake.player)) {
name.copyValues(snake);
}
objout = new ObjectOutputStream(map.get(name)
.getOutputStream());
objout.writeObject(move);
objout.flush();
//rest of code goes here. Closing brackets as above.
If I write the line
objout = new ObjectOutputStream(map.get(name).getOutputStream());
before the compound statement
if (name.player.equals(snake.player)) {
name.copyValues(snake);
}
I seem to get rid of the StreamCorrupted Exception.
Any suggestions as to why this is happening would be most welcome.

I too faced same exception and issue as explained above, was,
while writing(sending) msg(object), I was creating new OutputObjectStream, as below
//client or server side
while(true)
{
ObjectOutputStream out = new ObjectOutputStream(s.getOutputStream());
out.writeObject(some_msg_object);
}
/* but while reading(receiving), I was not creating new inputObjectReader
ie */
//on other side
while(true)
Message msgReceived = (Message)inputObjectReader.readObject();
and this resulted above exact same education,
therefore, if sending msg, by creating new OutputStream, receive it by creating new InputStream viceversa, is sending using same already created OutputStream receive by already created InputStream.....
