In an attempt to fulfil this code, the "no answer" program. How do you fix that?

if(ChoiceRe.getText()=="Обычный"){
    System.out.println("Обычный режим запущен");
    time.progressProperty().bind(progress);
    normalTime=normalTime*60;
    normalTime=normalTime*1000;
    for(int row=0;row<100;row++){
        try {
            Thread.sleep(2700000);
        } catch (InterruptedException e) {}
        progress.setValue(progress.getValue()+0.01);
    }
}

First for the use of that collection I recommend specifying the type of data it will contain, this is done soVector<Clientes> vector = new Vector<Clientes>(); and if you have java 8 you can infer the second parameterVector<Clientes> vector = new Vector<>(); One way is with for improved can be used from Java 1.7.The improved for is as followsfor(TipoDeDatos cualquierNombreDeVariable:nombreDeColeccion){ System.out.println(cualquierNombreDeVariable.getCampo()); } your collection must implement the iterable interface, and it is the case of Vector.Your code would remain:import javax.swing.*; import java.util.*; public class AgregarClientes { public AgregarClientes() { Vector<Clientes> vector = new Vector<Clientes>(); Clientes clientes = new Clientes(); clientes.setNombre(JOptionPane.showInputDialog("Digite el nombre")); clientes.setApellido(JOptionPane.showInputDialog("Digite el apellido")); clientes.setIdentificacion(Double.parseDouble(JOptionPane.showInputDialog("Digite la identificacion"))); clientes.setTelefono(Double.parseDouble(JOptionPane.showInputDialog("Digite el telefono"))); clientes.setTipocliente(Integer.parseInt(JOptionPane.showInputDialog("Digite el tipo de cliente"))); clientes.setTipocliente(Integer.parseInt(JOptionPane.showInputDialog("Digite el tipo de vehiculo"))); clientes.setHoras(Integer.parseInt(JOptionPane.showInputDialog("Digite el numero de horas"))); clientes.setPlaca(JOptionPane.showInputDialog("Digite la placa del vehiculo")); vector.addElement(clientes); for(Clientes cliente:vector){ System.out.println(cliente.getNombre()); } } }

About the error that occurred while implementing https://gist.github.com/MahaSaka/c8c57e1b67b9a1152e82b8a93629f9c5 :java.lang.NullPointerExceptionIt came because it didn't start mAudioManager to use the method .requestAudioFocus.You must initialize it mAudioManager = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE); reason why in https://gist.github.com/MahaSaka/fd32902a9dc663580de343de0f1454d7 It doesn't explode anymore.About the error in the code:AudioAttributes playbackAttributes = new AudioAttributes.Builder() .setUsage(AudioAttributes.USAGE_GAME) .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC) .build(); http://segun%20la%20[documentaci%C3%B3n%20oficial][3] should only be used in versions with a min sdk marked API >= 21 . So if you try to run that code block in a lower version, it will cause you the exception:java.lang.ClassNotFoundException: Didn't find class "android.media.AudioAttributes$Builder"The solution here is to implement both forms by marking the code in a version or method with the annotation @RequiresApi.For example, so you should call to play the audio for the different versions:if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) { // Aqui debes hacerlo con AudioAttributes PlayAudioWithAttributes(R.raw.color_red); } else { // Aqui tienes que hacerlo de la otra forma, sin audio Attributes PlayAudioWithoutAttributes(R.raw.color_red); } // Para versiones API 21+ @TargetApi(Build.VERSION_CODES.O) public void PlayAudioWithAttributes(int audioResourceID) { //Create and setup the media player for the audio resource. mMediaPlayer = MediaPlayer.create(this, audioResourceID); mAudioManager = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE); AudioAttributes playbackAttributes = new AudioAttributes.Builder() .setUsage(AudioAttributes.USAGE_GAME) .setContentType(AudioAttributes.CONTENT_TYPE_MUSIC) .build(); AudioFocusRequest focusRequest = new AudioFocusRequest.Builder(AudioManager.AUDIOFOCUS_GAIN_TRANSIENT) .setAudioAttributes(playbackAttributes) .setAcceptsDelayedFocusGain(true) .setOnAudioFocusChangeListener(mOnAudioFocusChangeListener) .build(); //Request audio focus in order to play an audio file. The app needs to play a short audio file //so we will request AUDIOFOCUS_GAIN_TRANSIENT int result = mAudioManager.requestAudioFocus(focusRequest); if (result == AudioManager.AUDIOFOCUS_REQUEST_GRANTED) { //Start the audio file mMediaPlayer.start(); } } @TargetApi(Build.VERSION_CODES.O) public void PlayAudioWithoutAttributes(int audioResourceID) { // Aqui debes poner el codigo de como se hacia antes } For the old version (API < 21) I mean the method PlayAudioWithoutAttributesYou can check. https://gist.githubusercontent.com/kuccello/5816882/raw/d552ad2951b201f901d55ca41426cbc10fe59424/MusicPlayer.java which is the right way to implement it. According to the documentation, after making the audio focus request, you must leave it. Note, that that code uses a BroadcastReceiver, so you would only be interested in the part related to the requestAudioFocus And obviously you'll rule out the whole code that's related to the Broadcast. Good luck.

You're confusing. Code Inspection Compilation. Compilation, unlike inspection, is already the final verdict and is done not by IDE but by the compiler. The compiler only checks the syntaxis, but not the quality of the code, say a typical example, if the inspector can fight, for an unused variable, then the compiler doesn't care.

Use it. https://developer.android.com/reference/android/support/v4/app/NotificationCompat.html And remember ActionButtons only with Android 4.1SupplementTry S5 standard stack instead of Samsung's. https://play.google.com/store/apps/details?id=com.google.android.launcher Supplement 2Also recommend that the Samsungs use the non-zero parameter requestCode for PendingIntentPendingIntent resultPendingIntent = stackBuilder.getPendingIntent(1, PendingIntent.FLAG_UPDATE_CURRENT);

Methods https://docs.microsoft.com/en-us/dotnet/api/system.data.linq.itable-1.deleteonsubmit?view=netframework-4.8 ♪ https://docs.microsoft.com/en-us/dotnet/api/system.data.linq.itable-1.insertonsubmit?view=netframework-4.8 in fact, they do not remove or supply data to OBD. They're just... I don't know. As a matter of fact, it's either remote or embedded. A real request for disposal or supply of OBD occurs when the method is challenged https://docs.microsoft.com/en-us/dotnet/api/system.data.linq.datacontext.submitchanges?view=netframework-4.8 ♪How is the updating (update) in Linq to Sql. When the properties change their meanings: someEntity.SomeProp = "someValue"; - this creature. I don't know. It's like a change. And then, like, we need to call a method. SubmitChanges - a real request will be sent to the OBD.So your repository should have a method, usually called it. Savewhich will comply with the OBD request(s):public void Save() { context.SubmitChanges(); } This method is followed by methods. Delete♪ Insert and changes in properties. Method Edit I don't need it.As an option, it is possible to:public void Delete(T entity) { DataTable.DeleteOnSubmit(entity); context.SubmitChanges(); } public void Insert(T entity) { DataTable.InsertOnSubmit(entity); context.SubmitChanges(); } public void Edit() // хотя название Update тут будет лучше { context.SubmitChanges(); } In this option, the method Save No need. But semantics. Edit It looks bad: it's not clear that it needs to be called after changing the properties of the creatures.

The idea is to make a proportion between the two scales, these being:0 a 255-40 a 40Notice that the scales do not have the same base, and so we can adjust adding 40 scale -40 a 40 that gives a scale 0 a 80.With the two scales on the same basis the highest value of the two is divided to give the ratio:255 / 80 = 3,1875 We can say that the scale 0 a 255 It is 3,1875 times greater than scale 0 a 80. Then transform a value of 0 a 80 for this scale is only multiply by 3,1875.But how the values go from -40 a 40 you must first adjust the value to this scale 0 a 80 adding 40.See the following examples:Temperature 40: (40+40) * 3,1875 = 255Temperature 10: (40+10) * 3,1875 = 158,75Temperature -23: (40-23) * 3,1875 = 31,875Temperature -40: (40-40) * 3,1875 = 0If you notice the steps that have been made, you will see that it corresponds to the answer A, which is the correct one.

An ordinary solution to your problem would be to declare class. ContentViewer Total T:public partial class ContentViewer<T> : UserControl { public ObservableCollection<T> ItemsCollection { ... In your case, however, the problem is that it is impossible in the XAML to declare generic control is only supported by the controllers. specific Like.That's why your class will have to be broken. For example:public partial class ContentViewerBase : UserControl { public ContentViewerBase() { InitializeComponent(); MainGrid.DataContext = this; } } (and the same XAML).In the XAML, you can already be tied to collections, because Binding has a late contact. Collect on top:class ContentViewerGeneric<T> : ContentViewerBase { #region DP ItemsCollections public ObservableCollection<T> ItemsCollection { get { return (ObservableCollection<T>)GetValue(ItemsCollectionProperty); } set { SetValue(ItemsCollectionProperty, value); } } public static readonly DependencyProperty ItemsCollectionProperty = DependencyProperty.Register ( "ItemsCollection", typeof(ObservableCollection<T>), typeof(ContentViewerGeneric<T>)); #endregion } class ContentViewerOfDouble : ContentViewerGeneric<double> { } class ContentViewerOfString : ContentViewerGeneric<string> { } etc.Only " specific " classes such as ContentViewerOfDoubleof course.<local:ContentViewerOfDouble ItemsCollection="..."/>

Apparently Console.ReadLine() doesn't put the code on the pause in the docker.Make an expectation instead. Console.ReadLine()like that.var waiter = new ManualResetEventSlim(false); waiter.Wait(); Console.WriteLine("Stopping bot"); Add the methodprivate void Stop() { waiter.Set(); } And in method. HandleUpdateAsync write, for example, when you get a team. /stop I mean, don't let the bot stop any user, just yourself.if (/*получена команда /stop от админа бота*/) Stop();

You're not warning your class heirs. BaseApiObject 1 problem: collection editing. If the request comes from a conditional Internet, there's a big question: why do we need to change if it doesn't affect the server? That's why you better come back. IEnumerable<T>And better yet... IAsyncEnumerable<T> (Operator) yield No harm.It's also better to remove the synchronized version of the method. GetAsync ♪ Get: You choose the user how to return the result in sync. If your method is changed, the code of all the users of your method, i.e., the users of the method depend on its implementation, can go to hell. The result is the same, but the other, and the problems are different, despite the results that are worn out (e.g. dead-lock).That's why you never have to do methods that you can't change. It's the same thing not using the interfaces in the 1 million lines code.

I don't understand why it doesn't work.
