    Wasn't sure if this was to go here or in other. (Mod please move it if it should be somewhere else)

    I have noticed a large amount of posts that are doing something along the lines of
    public static void main(String[] args) throws Exception
    {
     
    }
    The reason that methods throw exceptions, is that the creators of that method believe that the program can still be saved. EG
    /**
     * If the program is in debug mode
     */
    public final boolean DEBUG = true;
    /**
     * Some Instance String
     */
    private String someString;
    /**
     * Get the first line from a file and save it to a variable
     */
    public void getFirstLine(File f)
    {
      try
      {
        BufferedReader in = new BufferedReader(new FileReader(f));
        someString = in.readLine();
        in.close();
      }catch(IOException e)
      {
        if(DEBUG)
        {
          e.printStackTrace():
        }
        System.err.println("An error occured reading the file, setting default properties");
     
        someString = "Yellow Unicorn";
      }
    }
    ...
