Java

Write a method called max that accepts a map whose keys are strings and whose values are integers as a parameter and returns the integer 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 movie names (strings) to the number of cinemas screening it (integers). Your method would return the integer representing the largest number of cinemas. Consider a map variable movies containing the following key/value pairs: {A=22, C=25, D=25, J=20, K=20, L=20, M=25, R=18, S=22} Three movies are screened in 20 cinemas (J, K and L), two movies in 22 (A and S ), and three movies in 25 (C, D, M). So a call of max(movies) returns 25. Ignore ties. {A=22, C=21, D=18, J=20, K=20, L=20, M=25, R=18, S=22} a call to max(movies) returns 21 since 21 is the highest integer. Hint: Use any appropriate auxillary data structure(s) as needed.
