Getting static value after deserialization

Question

Please clear my understanding why I am getting of value of company after deserialization. I know "Statics are implicitly transient, so we don't need to declare them as such."

    class Employee implements Serializable {
        String name;
        static String company = "My Company";

        public Employee(String name) {
            this.name = name;
        }
    }

    public class Test8 {
        public static void main(String[] args) throws Exception {
            Employee e = new Employee("John");
            serializeObject(e);// assume serialize works fine
            Employee e1 = deserializeObject(); // assume deserialize works fine
            System.out.println(e1.name + " " + e1.company);
        }

   public static void serializeObject(Employee e) throws IOException {
        FileOutputStream fos = new FileOutputStream("Test8.cert");
        ObjectOutputStream oos = new ObjectOutputStream(fos);
        oos.writeObject(e);
        oos.flush();
        oos.close();
    }

    public static Employee deserializeObject() throws IOException, ClassNotFoundException {
        FileInputStream fis = new FileInputStream("Test8.cert");
        ObjectInputStream oos = new ObjectInputStream(fis);
        return (Employee) oos.readObject();
    }


    }

Answer 1

Value of static field company was set first time you used Employee class. In your case it would be in line:

Employee e = new Employee("John");

This value didn't change since it wasn't serialized and deserialized so it stayed the same, which means

System.out.println(e1.name + " " + e1.company);

prints John My Company .

---

But even if you remove lines

Employee e = new Employee("John");
serializeObject(e);

from your code, and invoke only

public static void main(String[] args) throws Exception {
    Employee e1 = deserializeObject(); // assume deserialize works fine
    System.out.println(e1.name + " " + e1.company);
}

Employee class will still be loaded inside deserializeObject (by oos.readObject() method) so its static fields will also be properly initialized to its default values.
