I want write in file .txt and i try this:

save_arq.print("%s;%d:%f;", entry.getValue(), entry.getKey(), result);

I initialize the file this modo:

Scanner file_tf_idf = new Scanner(System.in);

FileWriter arq = new FileWriter("C:\tf_idf.txt");

PrintWriter save_arq = new PrintWriter(arq);

But i have error in save_arq.print.

My complete code:

public class tfidfWeights {



public Map<String, Integer> tfidf(Map<String, Integer> tf_C) throws IOException{



        Scanner file_tf_idf = new Scanner(System.in);

        FileWriter arq = new FileWriter("C:\tf_idf.txt");

        PrintWriter save_arq = new PrintWriter(arq);          



        Map<String, Integer> idf = new HashMap<String, Integer>();





        //Set<Integer> doc_id = new HashSet<Integer>(tf_C.keySet());

        Set<Entry<String, Integer>> set = tf_C.entrySet();

        Iterator it = set.iterator();



        Integer N_total = tf_C.size();



        while(it.hasNext()){

            //iterar o map

            Entry<String, Integer> entry = (Entry)it.next();



            double result = 0;

            result = Math.log10(N_total/entry.getValue());

            save_arq.print("%s;%d:%f;", entry.getValue(), entry.getKey(), result);

            System.out.print(result);

        }

        save_arq.close();

    }

}

There is no print method in the PrintWriter class that accepts those arguments. I'm assuming you wanted to use the printf() method, which accepts:

printf(String format, Object... args)

So your code would be:

save_arq.printf("%s;%d:%f;", entry.getValue(), entry.getKey(), result);
