What will be the output of the following program?
import java.io.*;
public class SaveSecrets {
public static void main(String[] args) {
User user = new User("My User Name", "My Password");
try {
ObjectOutput out = new ObjectOutputStream(new FileOutputStream("secrets.txt"));
user.writeExternal(out);
out.close();
ObjectInput in = new ObjectInputStream(new FileInputStream("secrets.txt"));
user.readExternal(in);
in.close();
} catch (Exception e) { }
System.out.println(user);
}
}
class User implements Externalizable {
private String userName;
private transient String password;
public User(String userName, String password) {
this.userName = userName;
this.password = password;
}
public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException {
String line = in.readUTF();
userName = line.split("~")[0];
password = line.split("~")[0];
}
public void writeExternal(ObjectOutput out) throws IOException {
out.writeUTF(userName + "~" + password);
}
public String toString() {
return userName + " " + password;
}
}
