Za tiste, ki ste se odločili, da boste zadomačo nalogo izbrali zahodne
filozofe, sem napisal en parser, ki poparsa tisto vhodno datoteko iz
neta v java.util.List, kjer so objekti tipa Person. Person je pa inner
class v projektu. Parse metoda je nepregledno napisana vendar dela :).
Vse kar morate spremeniti je vaš file location: (ni mi še uspelo, da
bi jih relativno na projekt bral)
final String FILE_LOCATION = "C:\\phil_tline.txt";
Še koda:
import java.util.List;
import java.util.LinkedList;
public class MyDemo extends PApplet { // Objektno dedovan applet
void setup()
{
final String FILE_LOCATION = "C:\\phil_tline.txt";
size(640, 480);
List personList = parseFile(FILE_LOCATION);
this.printOutPersonList(personList);
}
void draw()
{
background(255);
}
public List parseFile(String fileLocation){
List personList = new LinkedList();
InputStream is = null;
try {
is = new FileInputStream(new File(fileLocation));
BufferedReader br = new BufferedReader(new InputStreamReader(is));
String line;
while((line=br.readLine()) != null)
{
boolean bce = false;
boolean bceCe = false;
//Author regex
Pattern pat = Pattern.compile("^(\\D*)(c\\.)");
Matcher mat = pat.matcher(line);
//Birth regex
Pattern pat1 = Pattern.compile("(\\d*)");
//Death regex
Pattern pat2 = Pattern.compile("\\b(\\d*)");
//Get Living 1
Pattern pat3 = Pattern.compile("BCE");
//Get Living 2
Pattern pat4 = Pattern.compile("CE");
//Get description
Pattern pat5 = Pattern.compile("(\\.)(.*)(\\.)");
if(mat.find())
{
String person = mat.group();
//Get the ".c" out
person = person.substring(0, person.length() - 2);
//Delete person from line
String startAge = mat.replaceFirst("");
//Get wrid of whitespace
if(startAge.charAt(0) == ' ')
startAge = startAge.substring(1, startAge.length());
String ageStr = "";
mat = pat1.matcher(startAge);
String deathStr = "";
if(mat.find()){
ageStr = mat.group();
deathStr = mat.replaceFirst("");
}
int age = Integer.valueOf(ageStr).intValue();
mat = pat3.matcher(deathStr);
if(mat.find()){
bce = true;
deathStr = mat.replaceAll("");
}
mat = pat4.matcher(deathStr);
if(mat.find()){
bceCe = true;
}
mat = pat2.matcher(deathStr);
String deathS = "";
if(mat.find()){
deathS = mat.group();
deathStr = mat.replaceFirst("");
}
int death = Integer.valueOf(deathS).intValue();
mat = pat5.matcher(deathStr);
String desc = "";
if(mat.find()){
desc = mat.group();
desc = desc.substring(1, desc.length()-1);
}
//System.out.println("START" + deathStr + "END");
if(bce){
age = 0 -age;
death = 0 -death;
if(bceCe)
death = Math.abs(death);
}
//System.out.println("DATA: PERSON" +
person + " Birth:" + age + " Death:" + death + " Desc:" + desc);
Person per = new Person(person, age, death, desc);
personList.add(per);
}
//System.out.println(line);
}
}
catch (IOException e) {
e.printStackTrace();
}
return personList;
}
public void printOutPersonList(List list){
for(int i = 0; i < list.size() ; i++){
Person temp = (Person)list.get(i);
System.out.println("Name: " + temp.getName() + " Birth: " +
temp.getBorn() + " Died: " +
temp.getDied() + " Description: " +
temp.getDescription());
