private static void getDates(String quoteId, CVData data) {
    zqu__Quote__c quote = getQuote(quoteId);
    data.quote = quote;
    data.changeEffectiveDate = quote.zqu__StartDate__c;
    data.subscriptionTermStartDate = quote.zqu__SubscriptionTermStartDate__c;
    // end of current term
    data.endOfCurrentTerm = getEndOfCurrentTerm(
        quote.zqu__SubscriptionTermStartDate__c,

        (Integer) quote.zqu__InitialTerm__c
    );

    Integer numberOfTerms = initialTerm / 12;

    // make the terms list based on the initialTerm
    for (Integer i = 1; i <= numberOfTerms + 1; i++) {
      terms.add(termStartDate);
      termStartDate = termStartDate.addYears(1);  // here it shows error
    }
    System.debug(LoggingLevel.INFO, 'terms: ' + terms);

Hi sundar,

Your code is fine. Maybe you are getting this error because you would not have been pass the parameter properly in getEndOfCurrentTerm method.
You can take reference from this below code and pass the parameter in method like this:- 
ClassName.getEndOfCurrentTerm(date.parse('06/07/2012'),date.parse('06/07/2018'),50)
In case you find any other issue please mention. 
If you find your Solution then mark this as the best answer.

Hi,
Please find the solution.

I think there is no data inside termStartDate that's why you are not able to add 1 year to it.

Just debug termStartDate. i.e     System.debug(termStartDate);

or

Date datobj;
Integer dy = termStartDate.day();
Integer mon = termStartDate.month();
Integer yr = termStartDate.year();

integer year =yr+1;

String termsDate=dy+'/'+mon+'/'+yr;

Please mark is as the Best Answer if it helps You

Thank You

hi sundar,
try following code and check still you are facing the same error? 
private static void getDates(String quoteId, CVData data) {
    zqu__Quote__c quote = getQuote(quoteId);
    data.quote = quote;
    data.changeEffectiveDate = quote.zqu__StartDate__c;
    data.subscriptionTermStartDate = quote.zqu__SubscriptionTermStartDate__c;
    // end of current term
    data.endOfCurrentTerm = getEndOfCurrentTerm(
        quote.zqu__SubscriptionTermStartDate__c,
        quote.zqu__StartDate__c,
        (Integer) quote.zqu__InitialTerm__c
    );
}
  public static Date getEndOfCurrentTerm(
      Date termStartDate,
      Date effectiveDate,
      Integer initialTerm) {
    List<Date> terms = new List<Date>();

    Integer numberOfTerms = initialTerm / 12;

    // make the terms list based on the initialTerm
    for (Integer i = 1; i <= (numberOfTerms + 1); i++) {
		if(termStartDate != null){
      terms.add(termStartDate);
      termStartDate = termStartDate.addYears(1);  // here it shows error
    }
	}
    System.debug(LoggingLevel.INFO, 'terms: ' + terms);
    System.debug(LoggingLevel.INFO, 'EffectiveDate: ' + effectiveDate);

    // check if the effective date is less than each term start date
    for (Integer i = 0; i < terms.size(); i++) {
      if (effectiveDate <= terms[i]) {
        return terms[i].addDays(-1);
      }
    }
	  }


let me know if it helps you and mark it as best answer.
Thank you

some how i feel the startdate overwrite and become null , what could be the reason , the quote owner only cloning the quote and he can view all the fields
