Thread: ArrayList problem, getList and returning. help wanted

Hello

I got this problem
The last method to be added is a method that takes an employee name as argument and returns a list containing all journals that the employee is to see. You may use the following method header:

public ArrayList<Journal>getJournalList(String empName)

Normally I would just use the following:

 public List<ArrayList<String>> getJournalList()
    {
        return journalList;
    }

But when i need to return a list containing all journals that employee is to see, how do you do that? Any help or tips would be much appreciated.

Not enough info provided. What's the criteria that determines what journals an employee "is to see?" What does that mean?

Sorry,

I this class called journal

public class Journal { private String titel; private String publisher - Pastebin.com

And what im trying to make is a journal Collection

public class JournalCollection { // instance variables - replace the examp - Pastebin.com

And hence the problem with my question

Thank you, i've gotten this so far, but it won't seem to work

public JournalCollention getJournalList(string emp)
{
JournalCollection result = new Journalcollection();
for (Journal journal : journals)
{
if (journal.match(emq)) resutl.addJournal(journal);
}
return result;
}
 
journal.match(..)

public ArrayList<Journal>getJournalList(String empName)
    {
    JournalCollection result = new Journalcollection();
    for (Journal journal : journals)
    }
    {
    if (journal.match(empName)boolean match(String empName);
    {
    return circulationList.contains(empName);
    } 
    {
    result.addJournal(journal);
    }
    {
    return result;
    }

Basicly, I understand what you mean by all your points, but I cant seem to write it so it works. And I cant decypher the syntax well enough, since im really struggling with this arrayList.

Yeah, im aware the code looks horrible in its current state. But I only wanted to list what i had sofar, im really struggling how to set up arrayLists since im a newbie and this is my first time messing around with them.

What im looking for is some really good pointers as to how this is written so it works.

I get that, but the problem is, I have been sitting with this problem for the last hours trying to rewrite it 2000 times. And so I can't really clean up the code since im at a total loss atm, as im having real issues with how an arraylist when getList is written. I would clean it up if I knew how.
