Here are my class:
public class MyClassToBePersisted implements Serializable {
String profile, school;
transient private int yearStarted;
public void Profile(String name, int age, String hobby) {
profile = name + " " + age + " " + hobby;
}
public void School(String nameOfSchool, int yearStarted) {
this.yearStarted = yearStarted;
school = nameOfSchool + " " + yearStarted;
}
public String getProfile() {
return profile + school;
}
}
public class SerializeMyClassToBePersisted {
public static void main(String[] args) {
String filename = "sample.txt";
if (args.length > 0) {
filename = args[0];
}
MyClassToBePersisted mc = new MyClassToBePersisted();
mc.Profile("Mike", 14, "Swimming");
mc.School("Poly", 1998);
FileOutputStream fos = null;
ObjectOutputStream out = null;
try {
fos = new FileOutputStream(filename);
out = new ObjectOutputStream(fos);
out.writeObject(mc);
out.close();
} catch (IOException e) {
e.printStackTrace();
}
System.out.println(mc.getProfile());
}
}
public class DeserializeMyClassToBePersisted {
public static void main(String[] args) {
String filename = "sample.txt";
if (args.length > 0) {
filename = args[0];
}
// Deserialize the previously saved
// PersistentTime object instance.
MyClassToBePersisted mc = null;
FileInputStream fis = null;
ObjectInputStream in = null;
try {
fis = new FileInputStream(filename);
in = new ObjectInputStream(fis);
mc = (MyClassToBePersisted) in.readObject();
in.close();
} catch (IOException ex) {
ex.printStackTrace();
} catch (ClassNotFoundException ex) {
ex.printStackTrace();
}
System.out.println(mc.getProfile());
}
}
When I run the SerializeMyClassToBePersisted.java I get file with
unreadable and readable text.
When I run the DeserializeMyClassToBePersisted.java It reads it
correctly. My problem is the yearStarted is transient and should be
null after it gets deserialized right? I'm not getting that.
