How to create a class that creates a instance of the UserInfo class and writes the object to an output stream?

Create a class that creates a instance of the UserInfo class and writes the object to an output stream as shown in Code Sample. The output stream in this example is a file called "name.out". The important thing to note from Code Sample is that the writeObject method can be called any number of times to write any number of objects to the output stream.

Code Sample: SaveInfo.java
import java.io.*;
import java.util.Date;

public class SaveInfo {

public static void main
(String argv[]) throws Exception {
FileOutputStream fos = 
new FileOutputStream("name.out");
ObjectOutputStream oos = 
new ObjectOutputStream(fos);
// create two objects
UserInfo user1 = new UserInfo("Java Duke");
UserInfo user2 = new UserInfo("Java Blue");
// write the objects to the output stream
oos.writeObject(user1);
oos.writeObject(user2);
oos.flush();
oos.close();
fos.close();
}
}
