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 "##-########-#".
It's a holiday in the US today, so we're taking a long weekend. We flip back to a classic story of a company wanting to fill 15 different positions by hiring only one person. It's okay, Martin handles the database. Original - Remy
A curious email arrived in Phil's Inbox. "Windows Support Engineer required. Must have experience of the following:" and then a long list of Microsoft products.
Phil frowned. The location was convenient; the salary was fine, just the list of software seemed somewhat intimidating. Nevertheless, he replied to the agency saying that he was interested in applying for the position.
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()
Combining Java with lower-level bit manipulations is asking for trouble- not because the language is inadequate to the task, but because so many of the developers who work in Java are so used to working at a high level they might not quite "get" what they need to do.
Victor inherited one such project, which used bitmasks and bitwise operations a great deal, based on the network protocol it implemented. Here's how the developers responsible created their bitmasks:
Kate inherited a system where Java code generates JavaScript (by good old fashioned string concatenation) and embeds it into an output template. The Java code was written by someone who didn't fully understand Java, but JavaScript was also a language they didn't understand, and the resulting unholy mess was buggy and difficult to maintain.
Why trying to debug the JavaScript, Kate had to dig through the generated code, which led to this little representative line:
Andre has inherited a rather antique ASP .Net WebForms application. It's a large one, with many pages in it, but they all follow a certain pattern. Let's see if you can spot it.
protected void btnSearch_Click(object sender, EventArgs e)
{
ArrayList paramsRel = new ArrayList();
paramsRel["Name"] = txtNome.Text;
paramsRel["Date"] = txtDate.Text;
Session["paramsRel"] = paramsRel;
List<Client> clients = Controller.FindClients();
//Some other code
}
