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);
