Why the file.txt is not updated inside the IDE (using BufferedWriter)?

[redcodeheaven]

Hi all ,I came across the internet for such a method to write to a file,although I am taking java but never really learned about buffered writer instead I took Printstream class;my question is why the records of the file created using this method are not updated (if Ineed to add records) inside IntellijIdea,instead you have always to check the file using Notepad,thanks for any reply here is the code:

public void writeToFile(String filename){
 
 
            BufferedWriter bufferedWriter = null;
 
            try {
 
                // Construct the BufferedWriter object
                bufferedWriter = new BufferedWriter(new FileWriter(filename));
 
                // Start writing to the output stream
                bufferedWriter.write("Writing line one to file");
                bufferedWriter.newLine();
                bufferedWriter.write("Writing line two to file");
                bufferedWriter.newLine();                        
                bufferedWriter.write("Writing line three to file");
            } catch (FileNotFoundException ex) {
                ex.printStackTrace();
            } catch (IOException ex) {
                ex.printStackTrace();
            } finally {
 
                // Close the BufferedWriter
                try {
                    if (bufferedWriter != null){
                        bufferedWriter.flush();
                        bufferedWriter.close();
                    }
                } catch (IOException ex) {
                    ex.printStackTrace();
                }
            }
        }

Please use "code tag". By the way i tested this code, it's running successfully. But what do you mean by "inside the IDE"?

Each time you run that code it'll create a new file (the old contents are lost). If that's not what you want read the API documentation for the FileWriter class; it also has a constructor that appends your data to the already existing contents.

kind regards,
