Ich versuche Objekt von benutzerdefinierten Klasse über Sockets zu senden, aber es führt den „java.io.NotSerializableException“

Das Folgende ist die benutzerdefinierte Klasse, deren Gegenstand ich passieren versuche:Ich versuche Objekt von benutzerdefinierten Klasse über Sockets zu senden, aber es führt den „java.io.NotSerializableException“

package dataEx; 

    import java.io.Serializable; 
    import java.util.*; 

    public class dataToExchange implements Serializable 
    { 


     public Integer frameIndex; 
     public Integer xOffsetTank; 

    }

den einschlägigen Client-Code, wo die Daten ist ein Ziel I, durch write Methode übergeben versuchen:

dataToExchange data=new dataToExchange() ; 
    data.frameIndex=2; 
    data.xOffsetTank=23; 
    output.writeObject(data);

der Server das Objekt zu empfangen und den Druck

data_recv=(dataToExchange)input.readObject(); 
    System.out.println(data_recv.xOffsetTank);

Der Stacktrace:

Falsche Klasse. Überprüfen Sie die Ausnahme erneut. Sie versuchen, eine Klasse mit dem Namen 'dataToExchange' zu serialisieren, deren Definition in der Klasse 'proclient' verschachtelt ist und die nicht serialisierbar ist. Sie haben übersehen, dass Sie zwei Klassen mit dem gleichen Namen haben, was hiermit eine schlechte Idee ist.

Sie hatten Recht !! Vielen Dank. Was Dummheit, ich ursprünglich dataToExchange für Server und Client getrennt, dann habe ich herausgefunden, dass eine gemeinsame Klasse sollte da sein, aber dann in ctrl-zeding den Code n-mal habe ich vergessen, die früheren Kopien von dataToExchange zu entfernen. Serviert mich richtig, ich sollte mehr Aufmerksamkeit auf die Stack-Spur, seine Größe zu sehen, ich überfliege es nur, jetzt weiß ich seine Bedeutung. Nochmals vielen Dank, du hast meine Frustration beendet, und da ich gerade mit Steckdosen anfange, hast du mir sehr geholfen. –

Ich versuche Objekt von benutzerdefinierten Klasse über Sockets zu senden, aber es führt den „java.io.NotSerializableException“
