Fetch the slot value used for a previous intent(method) and use it in current method?

Question

I am working on building an alexa skill where the requirement is to fetch the value for previous slot..

User:  Alexa,create an appointment
Alexa: please state the subject for appointment
User : subject is {subject}
Alexa: on which day?
User : {Day}
Alexa : Appointment has been created with {subject} on {day}

Final method should fetch values from previous slots(subject and date) and create an appointment. So far i'm able to fetch slot value for current intent...but i would like to fetch the slot value for previous intent and use it in the current method.

*Example

protected SpeechletResponse method1(Intent intent,Session session)throws 
Exception{
    SpeechletResponse response=null;

Map<String, Slot> slots =  intent.getSlots();
Slot example = slots.get(SampleSlot);
String value=example.getValue().toString();
String output="something";

response = SpeechletResponseHelper.getSpeechletResponse(output, reprompt, 
true);
    return response;
}

protected SpeechletResponse method2(Intent intent,Session session)throws 
Exception{
SpeechletResponse response=null;

****How to fetch the slot value used for method1 and use it in method2? ****

response = SpeechletResponseHelper.getSpeechletResponse(xxxx, reprompt, 
true);
return response;
}

Is this possible?If so how can i do it?

Thanks and Regards

Answer 1

I used sessions to achieve my query like this....

Map<String, Slot> slots =  intent.getSlots();
Slot example = slots.get(SampleSlot);
session.setAttributes(Sample_String);
session.getAttributes(SampleSessionString);
