Question

Here’s the code:

        Scanner scan = new Scanner(new FileReader ("C:\\mytext.txt"));
        HashMap<String, Integer> listOfWords = new HashMap<String, Integer>();

        while(scan.hasNextLine())
        {
            Scanner innerScan = new Scanner(scan.nextLine());
            boolean wordExistence ;
            while(wordExistence = innerScan.hasNext())
            {
                String word = innerScan.next(); 
                int countWord = 0;
                if(!listOfWords.containsKey(word)){ already
                    listOfWords.put(word, 1); 
                }else{
                    countWord = listOfWords.get(word) + 1; 
                    listOfWords.remove(word);
                    listOfWords.put(word, countWord); 
                }
            }
        }

        System.out.println(listOfWords.toString());

The problem is, my output contains words like :

document.Because=1
document.This=1
space.=1

How do I handle this full stop’s that are occuring?(And for further issues, I think any sentence terminator would be an issue, like question mark or exclamation mark).

Take a look at the class notes for the Scanner API, in particular the paragraph on using delimiters other than whitespace.
