How to print this output in text file in java?

Question

I have calculated the words and now displaying it in console. But I want to write the console output to a text file. how to do this?

String[] wrds   = counter.getWords(WordCounter.SortOrder.BY_FREQUENCY);
int[] frequency = counter.getFrequencies(WordCounter.SortOrder.BY_FREQUENCY);        

int n = counter.getEntryCount();
for (int i=0; i<n; i++) 
{
    This should be written in text file///// System.out.println(frequency[i] + " " + wrds[i]+" "+ counter.getWordCount());

Have you tried searching for tutorials on this at all? There is a plethora of great examples if you just google "java writing out to a file" or similar. — Quetzalcoatl, Feb 13 '13 at 15:25

String[] wrds   = counter.getWords(WordCounter.SortOrder.BY_FREQUENCY);
int[] frequency = counter.getFrequencies(WordCounter.SortOrder.BY_FREQUENCY);        
String texttoWrite = "";
int n = counter.getEntryCount();
for (int i=0; i<n; i++) 
{
    texttoWrite += frequency[i] + " " + wrds[i]+" "+ counter.getWordCount();
}
try{
 FileWriter fstream = new FileWriter("out.txt");
 BufferedWriter out = new BufferedWriter(fstream);
 out.write(texttoWrite);
 out.close();
 }catch (Exception e){
  System.err.println("Error: " + e.getMessage());
 }
}

Updated the code. Try it. – NEO Feb 13 '13 at 15:38
thanks but I want to write as line by line. { texttoWrite += frequency[i] + " " + wrds[i]+" "+ counter.getWordCount()+"\n"; } is it correct? – Ameer Feb 13 '13 at 15:47

Yes. You have to append a new line escape character to print line by line. – NEO Feb 13 '13 at 15:50

How about something like this?

FileWriter fstream = new FileWriter(fileName);
BufferedWriter fbw = new BufferedWriter(fstream);
for (int i=0; i<n; i++) {
    fbw.write(frequency[i] + " " + wrds[i]+" "+ counter.getWordCount()+ "\n");
}

Check out FileWriter

FileWriter fw = new FileWriter("path location");
fw.write(frequency[i]....);
fw.close();

Open a file with the file object. And write to the file in stead of the console (or do both). Close the file. What is the real problem?
