Loop schema for writing to a file

When we write data on a file, we usually make use of a loop structured as follows:

PrintWriter out = ...
while (condition) {
   out.println(data);
   ...
}
out.close();

Note: The condition for terminating the loop does not depend on the file, but on the data which we are writing to the file.

Example: Method that writes an array of strings on a file. Both the array of strings and the filename are passed as parameters to the method.

import java.io.*;

public static void saveArray(String[] v, String filename) throws IOException {
  FileWriter f = new FileWriter(filename);
  PrintWriter out = new PrintWriter(f);
  for (int i = 0; i < v.length; i++)
    out.println(v[i]);
  out.close();
  f.close();
}
