Which is the best way to create file and write to it in Java [closed]

Answer 1

I prefer:

boolean append = true;
boolean autoFlush = true;
String charset = "UTF-8";
String filePath = "C:/foo.txt";

File file = new File(filePath);
if(!file.getParentFile().exists()) file.getParentFile().mkdirs();
FileOutputStream fos = new FileOutputStream(file, append);
OutputStreamWriter osw = new OutputStreamWriter(fos, charset);
BufferedWriter bw = new BufferedWriter(osw);
PrintWriter pw = new PrintWriter(bw, autoFlush);
pw.write("Some File Contents");

which gives you:

1. Decide whether to append to the text file or overwrite it.
2. Decide whether to make it auto-flush or not.
3. Specify the charset.
4. Make it buffered, which improves the streaming performance.
5. Convenient methods (such as println() and its overloaded ones).
