Java returns data of the form 2015 3/20-3/31 for a given date

One of the most recent projects has a foreground for the table header requirements:

Returns the shape of a given date period as

Mar 2015 3/20-3/31
APR 2015 4/1-4/30

This month year data, simply write down the code, temporarily did not think of a better way

For example, the passed in parameter is "2015-03-20"-"2016-04-08" such form

Three-stage processing:

First paragraph: The end of the start date of the start date

Second paragraph: Data for all months between the start and end months

Third paragraph: End date of the beginning of the month to the end date
