date inn = integer.valueof(trans.stdate.trim()) + integer.valueof(payment.Net__c);

Getting the following error System.TypeException: Invalid integer: 12/06/2012

Here trans.stdate is of string Type.& My Requirement is 12/06/2012 + 4 = 12/10/2012.

How can I acheive it

Possible Suggestion/Solution #1

Well for starters Integer + Integer == Integer so you'll never get a date with your current operation.

But if trans.stdate is a String representation of a date your code should look something like:

Date inn = Date.parse(trans.stdate) + Integer.valueof(payment.Net__c);

There is also the Date.valueOf(string) static method but that only accepts dates in the format yyyy-MM-dd so wouldn't match the format in your error message
