Write a method called max that accepts a map whose keys are strings and whose values are double as a parameter and returns the double value that has the highest value in the map. If the map is empty, throw an exception. For example, suppose the map contains mappings from month names (strings) to the average temperature in that month (double). Your method would return the double representing the highest value. Consider a map variable monthlyTemp containing the following key/value pairs: {Jan-22.2, Feb-24.3, Mar-57.7, April-69.2, May-80.3, June-85.36, July-94.9, Aug-91.2, Sep-89.3,Oct=77. 2, Nov-48.21, Dec=18.3} a call to max(monthlyTemp) returns 94.9 since July has that temperature and that is the maximum of all the temperatures. You can assume that there are no duplicate temperatures. Hint: Use any appropriate auxillary data structure(s) as needed.
