Write an algorithm in pseudocode to describe the serialization. The algorithm should show when handles are defined or substituted for classes and instances. Describe the serialized form that your algorithm would produce when serializing an instance of the following class Couple.

Question

```
class Couple implements Serializable{
private Person one;
private Person two;
public Couple(Person a, Person b) {
one = a;
two = b;
}

}
```

Answer 1

The algorithm must describe serialization of an object as writing its class information followed by the names and types of the instance variables.Then serialize each instance variable recursively.

```

serialize(Object o) {

c = class(o);

class_handle = get_handle(c);

if (class_handle==null) // write class information and define class_handle;

write class_handle

write number (n), name and class of each instance variable



object_handle = get_handle(o);

if (object_handle==null) { define object_handle; for (iv = 0 to n-1)

if (primitive(iv) ) write iv else serialize( iv)

}

write object_handle

}

```

To describe the serialized form that your algorithm would produce when serializing an instance of the class Couple.



For example declare an instance of Couple as

```

Couple t1 = new Couple(new Person("Smith", "London", 1934), new Person("Jones", "Paris", 1945));

```

The output will be:
