Double division behaving wrongly

Question

I have a HashMap called List wordFreqMap whose size is 234

wordFreqMap = {radiology         


        

Answer 1

You're performing an integer division and then type casting:

tf = (double) ( word.getValue() / noOfTerms );
                ^-----integer division----^

Type cast one of the elements in the division to convert into a floating point division:

tf = ((double)word.getValue()) / noOfTerms;
