Find the Duration in Months between the contents in an Iterator

Question

    Iterator<String> termIncomeKeys = termIncome.keySet().iterator();
    while(termIncomeKeys.hasNext()){
        String month = termIncomeKeys.next();
        System.out.println(month);
    } The above code is printing month as
Jan(2012) - Jan(2012)
Feb(2012) - Mar(2012)
Apr(2012) - May(2012)
Jun(2012) - Jun(2012)
Jul(2012) - Oct(2012)What I want to achieve is I want to print the duration in terms of months between each of the entries. That is, Duration between first entry is 1 month, duration between second is 2 and so on.

Answer 1

What you print is a string. You can't do calculations on a string. You have first to disassemble the string into parts and interpret what each part contains. There is nothing out of the box in java to do this. On the other side it's not too difficult to do it yourself.
