Count each word on a string Java -

i need make program reads multiple lines stdin count words , print words number of ocurrence if 2 or more words have same number have sort them alphabetically. e.g:

hello world morning hello 

the output should be:

hello: 2 good: 1 morning: 1 world: 1 

i want know best way this, hashmap best way?

this more interesting question looks on surface.

basically hashmap<string, integer> choice, build map words count.

you want entryset() out of map , drop entryset() map new arraylist<entry<string, integer>>. can use collections.sort sort arraylist custom comparator first sorts value , key.

i'm not going provide code if you've specific questions of steps feel free ask.
