[java programming] LAB 1043 - Serializtion

[Alexander Weißer]

Hi.

I have a little problem while implementing the homework 1043.  
Everything works fine, but the transient field

int yearStarted (this is transient field)

everytime is 0;

Here is my Class School:
public class School implements Serializable{

     private String nameOfSchool;
     transient private int age;

     public School(String nameOfSchool, int age){
         this.nameOfSchool = nameOfSchool;
         this.age = age;
     }

     public static School getSchool(String nameOfSchool, int age){
         return new School(nameOfSchool, age);
     }

     @Override
     public String toString(){
         StringBuffer myBuffer = new StringBuffer();
         myBuffer.append(this.nameOfSchool+" ,"+this.age);
         return myBuffer.toString();
     }

}

here is the serializeMain:
public class SerializeMyClass{

     public static void main(String [] args){

         String filename = "MyClassToBePersisted.ser";
         if(args.length > 0) {
             filename = args[0];
         }

         MyClassToBePersisted myPersisted = new  
MyClassToBePersisted(School.getSchool("Scholname2", 6),  
Profile.generateProfile("ProfileName2", 99, "myHobby2"));


         // Serialize the object instance and save it in
         // a file.
         FileOutputStream fos = null;
         ObjectOutputStream out = null;
         try {
             fos = new FileOutputStream(filename);
             out = new ObjectOutputStream(fos);
             out.writeObject(myPersisted);
             out.close();
         } catch(IOException ex) {
             ex.printStackTrace();
         }

         System.out.println("Current time is saved into " + filename);
     }
}

here is the DeserializeMain:
public class DeserializeMyClass {

     public static void main(String [] args) {

         String filename = "MyClassToBePersisted.ser";
         if(args.length > 0) {
             filename = args[0];
         }

         // Deserialize the previously saved
         // PersistentTime object instance.
         MyClassToBePersisted myPers = null;
         FileInputStream fis = null;
         ObjectInputStream in = null;
         try {
             fis = new FileInputStream(filename);
             in = new ObjectInputStream(fis);
             myPers = (MyClassToBePersisted)in.readObject();
             in.close();
         } catch(IOException ex) {
             ex.printStackTrace();
         } catch(ClassNotFoundException ex) {
             ex.printStackTrace();
         }

         // print out restored time
         School mySchool = myPers.getSchool();
         Profile myProfile = myPers.getProfile();

         System.out.println("School: "+mySchool.toString());
         System.out.println("Profile: "+myProfile.toString());
     }
}

Thanks for your help.
