All times are GMT +2. The time now is 02:57 AM.

Adding a Phone object into a Student, Employee objects.

I am a bit new to java, so bare with me. And ill try to explain as best as i can .

I have to read in a file that that has Student, Employee, Faculty....such as name, last name, salary...etc

Example of a file input

Java Code:




Student, John, Doe, [email]johnDoe[At]yahoo.com[/email], 123,Wonderland Ave, 21323,TX
PhoneNumber,Cell,111,222,3333
Student, Jesus,Satan,[email]jesus[At]satan.com[/email,666, HeavenHell Dr., 666666,CA
PhoneNumber,Work,111,333,5555

Java Code:




      while(input.hasNext()){

                        String [] tokens = input.next().split(",");

                        String  objectType = tokens[0];



                        if (objectType.equalsIgnoreCase("Person")){
                                String firstName = tokens[1];
                                String lastName = tokens[2];
                                Address address  = new Address (Integer.parseInt(tokens[3]), Integer.parseInt(tokens[4]), tokens[5], tokens[6], tokens[7], Integer.parseInt(tokens[8]));
                            PhoneNumber phoneNumber = new PhoneNumber(tokens[1],Integer.parseInt(tokens[1]), Integer.parseInt(tokens[2]),Integer.parseInt(tokens[3]));
                                String emailAddress = tokens[9];

                                Person p = new Person(firstName, lastName, emailAddress, address,phoneNumber);

                                person.add(p);
                        }

                       else if (objectType.equalsIgnoreCase("Phone Number")){

                                String type = tokens[1];
                                int areaCode = Integer.parseInt(tokens[2]);
                                int prefix = Integer.parseInt(tokens[3]);
                                int suffix = Integer.parseInt(tokens[4]);

                                PhoneNumber ph = new PhoneNumber(type,areaCode,prefix,suffix);
                                
                                phoneList.add(ph);
                                
                        }

                        else if (objectType.equalsIgnoreCase("Student")){

                                String firstName = tokens[1];
                                String lastName = tokens[2];

                                Address address  = new Address (Integer.parseInt(tokens[3]), Integer.parseInt(tokens[4]),tokens[5], tokens[6], tokens[7], Integer.parseInt(tokens[8]));
                                String emailAddress = tokens[9];
                                String classStanding = tokens[10];

                                PhoneNumber phoneNumber = new PhoneNumber(tokens[1],Integer.parseInt(tokens[2]), Integer.parseInt(tokens[3]),Integer.parseInt(tokens[4]));



                                Student s = new Student(firstName, lastName,emailAddress,address,phoneNumber, classStanding);
                                person.add(s);

                        }

There is more code, but it's repetitive. Now, I keep getting an error. Array of bounds. I believe i get the error because the phone number. The phone number is on the next line

I created a different arraylist for phonenumber, but I dont know how to match it with the correct person, student, employee...etc. Any help?

MergeSort with Comparable and Lists

Hello guys!

I have big problem with mergesort in Java. I can't figure out why it do not works.

I need write it on lists using Comparable. Here is piece of code:

Java Code:


class MergeSort{
  Comparator _comparator;
  List lista = new ArrayList<>();
  List list_temp = new ArrayList<>();



MergeSort(Comparator comparator){
    _comparator = comparator;
}
void sort(List lista){
    this.lista = lista;

    mergesort(0, lista.size()-1);

}

void mergesort(int start, int end){
   if(start < end){
       int mid = start + (end-start)/2;

       mergesort(start, mid);
       mergesort(mid+1, end);

       merge (start, mid, end);
   }


}

void merge(int start, int mid, int end){

    int i = start;
    int j = mid + 1;
    int k = start;

    for(int h = start; h <= end; h++)
        list_temp.add(lista.get(h));

   while (i <= mid && j <= end) {
        if (_comparator.compare(list_temp.get(i),list_temp.get(j)) <= 0) {
            lista.set(k, list_temp.get(i)); 
            i++;
        } 
        else{
            lista.set(k, list_temp.get(j));  
            j++;
        }
       k++;

    while (i <= mid) {
        lista.set(k, list_temp.get(i));  
        k++;
        i++;
    }
    }



  }

 final class NaturalComparator implements Comparator{
          public static final NaturalComparator INSTANCE = new NaturalComparator();

          NaturalComparator(){}

         @Override
          public int compare(Object left, Object right) throws ClassCastException{
                  return ((Comparable) left).compareTo(right);
          }
}

I have tried everything, still no results. It's return list with random placed numbers.

Thnak you for any advice!

Sending Game Data to Server

Hi! I've been doing some work with Java Networking, specifically a Chat that sends a string to a server which then broadcasts to the other clients. I would like to create a game, but I am wondering how I would send data to the server in such a way that when it goes to the other clients, it doesn't confuse information.

For instance, how would I send the x and y coordinates of an object to a server. Please note that I would have other variables that might not be integers/doubles/floats, but maybe booleans, chars, or strings.

However, one thing that I was thinking is, would it be better (and possible) to send a whole class, such as a "spaceship" class or something like that. That way, the class would already contain all the variables.

In any case, thanks in advance!

Netbeans won't parse Expression Language in a JSP page

Hi, i've this code

PHP Code:
















<%@ taglib prefix="c" uri="http://ift.tt/QfKAz6" %>
<%@page import="Javabean.Articolo"%>
<%@page import="java.util.ArrayList"%>
<%@page contentType="text/html" pageEncoding="UTF-8"%>

<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
   
         <%
       
          String nome="porcodio";
          %>
         
          <div> ${nome}</div>
         
    </body>
</html>

I'm using Netbeans with glassfish server 4. When i try to launche the web page, i see that "nome" is not printed... Why?

My older projects that uses EL, still works fine, while this wont' parse the syntax... why??
