public class MainClass {
  public static void main(String[] a) {
    FileWriter writer;
    try {
      writer = new FileWriter("myFile.txt");
      char c = 'A';
      writer.write(c);
      writer.close();
    } catch (IOException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    }
