Question

Code:

    Iterator<String> termIncomeKeys = termIncome.keySet().iterator();
    while(termIncomeKeys.hasNext()){
        String month = termIncomeKeys.next();
        System.out.println(month);
    }

The month is printed 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

I do not know if there is a ready-made class that could parse these strings for you, but the logic is simple:

convert the three-letter months to numbers (e.g. 0-11), and convert the years to numbers as well.
The difference is <year-diff>*12 + <month-diff>, where <month-diff> might be negative.
