I have a AWT Frame which consists 3 text fields
namely for ex:  emp Name,dept and salary . in addition the frame consists 2 buttons, save and exit.

When i enter the data in the Text Fields and click save
the data should be saved into an object and not inside a database table nor inside a .dat file.

Again I shud retrive back the data from the object and display the contents onto another Screen.

You can create this object.

public class Credentals implements Serializable
{
     String name;
     String dept;
     String salary;
}

You store variables from text fields as data members of this class.

For example:

credentals.name=nameField.getText();
credentals.dept=deptField.getText();
credentals.salary=salaryField.getText();

The persistance is achieved using ObjectInputStream and ObjectOutputStream.

ObjectOutputStream out=new ObjectOutputStream(new FileOutputStream("credentals"));
out.writeObject(credentals);

At the start of the program you can retrieve the credentals with:

ObjectInputStream in=new ObjectInputStream(new FileInputStream("credentals"));
Credentals credentals=(Credentals) in.readObject();
