如何在使用反序列化时修复java.lang.ClassNotFoundException

Question

我在Java方面遇到了问题，如果我使用序列化，它可以很好地工作，但是当我使用反序列化时，它会抛出一个Java.lang.ClassNotFoundException。

Exception in thread "main" java.lang.ClassNotFoundException: javatpointpractice.Information

    at deserializer.Deserializer.main(Deserializer.java:21)

public class Deserializer {

    public static void main(String[] args) throws FileNotFoundException, IOException, ClassNotFoundException {
            
        Information ms = null;
        
        FileInputStream fileInput = new FileInputStream("C:\\Users\\usetr\\Documents\\Java WorksSpace\\NETBEANS\\TutorialsPointPractice\\outputs.ser");
        ObjectInputStream objectInput = new ObjectInputStream(fileInput);
        
        ms = (Information) objectInput.readObject();
        objectInput.close();
        fileInput.close();
        
        
        System.out.println(ms.name);
        System.out.println(ms.age);
    }
}

public class Information implements Serializable{
    
    String name;
    int age;

}

您的类名应该是information，而不是MySerializable。现在您已经解决了这个问题，解决了这个类的编译问题，代码就可以按照您的要求执行了。
