A recursive method or otherwise

[jite eghagha]

hello,
Every memo, or document, has words that are a waste of space, i need to store usefull words and their projectNumbers. (the code will explain)


I'll include chunks of code to help, but the general idea is to compare each token to every line read from a file;

in = new BufferedReader(new FileReader(inputFile))
X = in.readLine()// X is a word like: was, at, the, is, (useless words)
 
String S = BPO[i];// S is a long memo
StringTokenizer tokens = new StringTokenizer(S)
compare  token.nextToken to X
 
if they are unequal // code shows what to do;
 
i need to do this for BPO[0] to BPO[10]
 
ok that the general idea and here's my very bad attempt: (its not recursive, and it's not logically sound):
 
    public void compareToTextFile() {
        try {            
                String wordToExclud = "";            
                String stringToTokenize = "";
                stringToTokenize += bpo[i].getProjectTitle();
                stringToTokenize += bpo[i].getGeoArea();
                StringTokenizer tokens = new StringTokenizer(stringToTokenize); 
                while(tokens.hasMoreTokens()) {
                    String s = tokens.nextToken();
                    while ((wordToExclud = in.readLine()) != null) {
                        if(s.equalsIgnoreCase(wordToExclud) ) {
                            //do nothing
                        }
                        else {
                             KW = new KeyWords();
                             KW.setProjectNumber(bpo[i].getProjectNumber());
                             KW.setKeyWords(s);
                             KeyWords.add(KW);
                         }
                    }
                }
                i++;
                          
            in.close();
        } 
        catch (IOException ex) {
            ex.printStackTrace();        
        }
    }
thanks

Do you have a question?

[jite eghagha]

Thank you very much, here's the question. Will this code recursively weed out the unwanted text? If no, can any one please correct it so that it does.

 
    public void compareToTextFile() {
        try {            
                String wordToExclud = "";            
                String stringToTokenize = "";
                stringToTokenize += bpo[i].getProjectTitle();
                stringToTokenize += bpo[i].getGeoArea();
                StringTokenizer tokens = new StringTokenizer(stringToTokenize); 
                while(tokens.hasMoreTokens()) {
                    String s = tokens.nextToken();
                    while ((wordToExclud = in.readLine()) != null) {
                        if(s.equalsIgnoreCase(wordToExclud) ) {
                            //do nothing
                        }
                        else {
                             KW = new KeyWords();
                             KW.setProjectNumber(bpo[i].getProjectNumber());
                             KW.setKeyWords(s);
                             KeyWords.add(KW);
                         }
                    }
                }
                i++;
                while (i < bpo.length)
                    compareToTextFile();

Will this code recursively weed out the unwanted text?

What happened when you ran it?

[jite eghagha]

hhmmmm.

to run and test i iterated through List "KeyWords" and promted each object on the list for its projectNumber;

System.out.println(KW.getprojectNumber())

i got 418 project numbers; but they were all the same.

Plus, my recursion must be way of because changing this line:

while (i < bpo.length)
compareToTextFile();

to this line:

while (i < 1)
compareToTextFile();

still gives me 418 projectNumbers
