Program :

Step 1 - Coding

Create a text file c:/sunilos/TestWriteEmployee.java and copy below contents.

import java.io.FileOutputStream;
import java.io.ObjectOutputStream;

/**
 * A program to write in persist data file implemented Serializable interface.
 */
public class TestWriteEmployee {

    public static void main(String[] args) throws Exception{
       
        FileOutputStream fileOutputStream = new FileOutputStream("c:/sunilos/sunilos.ser");
       
        ObjectOutputStream out = new ObjectOutputStream(fileOutputStream);
       
        Employee emp = new Employee(1,"Sunil","OS");
       
        out.writeObject(emp);
       
        out.close();
       
        System.out.println("Obiect is successfully presisted");
       

    }

}

Step 2 - Deployment

1. Create a folder 'c:\sunilos'. 
2. Create or copy TestWriteEmployee.java into 'c:\sunilos' folder.
3. Open your command prompt and go to  'c:\sunilos'
   
4. Compile TestWriteEmployee.java with help of 
• javac TestWriteEmployee.java command. Command will create TestWriteEmployee.class file in the same folder.
  
5. Congratulations!! your Java program is ready to serve.

Step 3 - Testing

1. Make sure you are on Command Prompt under c:\sunilos directory
   
2. Now start your java program from command prompt with help of 
• java TestWriteEmployee command.
3. It will create file and object will be stored in
   
• c:/sunilos/sunilos.ser
  

Output

Obiect is successfully presisted

NOTE : transient variables do not persist during object serialization or transient variables are discarded during serialization.

Go to next program to read(deserialize) an object..
