Please write the code for this class in JAVA and implementing the required things :

Open a text file containing a variable number of words. Create an instance of your Hashtable class. Read in words from the text file until the end of the file is reached Look up the word in your hash table. If word is found Increment its count in the hash table otherwise Add the word to the hash table and set its count to 1. Print out the words and their counts
