                  Buliding English Dictionary Using Hashmap!

                  Hello,
                  I need your direction in my lab assignment, i dont know how how to start. I am supposed to implement a dictionary that stores English words and their multiple synonyms. Am required to use hashmap to build the dictionary and the data column in the HashMap should be a linkedlist.

                  please tell me how can i implement the hashmap with a linkedlist!!!
