Nina's team has a new developer on the team. They're not a junior developer, though Nina wishes they could replace this developer with a junior. Inexperience is better than whatever this Java code is.

Object[] test = (Object[]) options;
List<SchedulePlatform> schedulePlatformList = (List<SchedulePlatform>)((Object[])options)[0];
List<TableColumn> visibleTableCols = (List<TableColumn>)((Object[])options)[1];

Many nations have some form of national identification number, especially around taxes. Argentina is no exception.

Their "CUIT" (Clave Única de Identificación Tributaria) and "CUIL" (Código Único de Identificación Laboral) are formatted as "##-########-#".

Mark sends us a very simple Java function which has the job of parsing an integer from a string. Now, you might say, "But Java has a built in for that, Integer.parseInt," and have I got good news for you: they actually used it. It's just everything else they did wrong.

private int makeInteger(String s)
{
  int i=0;
  try
  {
    Integer.parseInt(s);
  }
  catch (NumberFormatException e)
  {
    i=0;
    return i;
  }
  i=Integer.parseInt(s);
  return i;
}

Frank inherited some code that reads URLs from a file, and puts them into a collection. This is a delightfully simple task. What could go wrong?

static String[]  readFile(String filename) {
    String record = null;
    Vector vURLs = new Vector();
    int recCnt = 0;

    try {
        FileReader fr = new FileReader(filename);
        BufferedReader br = new BufferedReader(fr);

        record = new String();

        while ((record = br.readLine()) != null) {
            vURLs.add(new String(record));
            //System.out.println(recCnt + ": " + vURLs.get(recCnt));
            recCnt++;
        }
    } catch (IOException e) {
        // catch possible io errors from readLine()
        System.out.println("IOException error reading " + filename + " in readURLs()!\n");
        e.printStackTrace();
    }

    System.out.println("Reading URLs ...\n");

    int arrCnt = 0;
    String[] sURLs = new String[vURLs.size()];
    Enumeration eURLs = vURLs.elements();

    for (Enumeration e = vURLs.elements() ; e.hasMoreElements() ;) {
        sURLs[arrCnt] = (String)e.nextElement();
        System.out.println(arrCnt + ": " + sURLs[arrCnt]);
        arrCnt++;
    }

    if (recCnt != arrCnt++) {
        System.out.println("WARNING: The number of URLs in the input file does not match the number of URLs in the array!\n\n");
    }

    return sURLs;
} // end of readFile()
