What is the best way to present the week of the year using the Joda-Time library? I look something as elegant as YearMonthto represent the month of the year.

After some searching, I found a solution using the class Partialfor this problem.

Partial yearWeek = new Partial(
                   new DateTimeFieldType[] {DateTimeFieldType.weekyear(), 
                                            DateTimeFieldType.weekOfWeekyear()}, 
                                            new int[] {year, week});
