How to convert a collection to an Array

Question

I need a function that returns dates as an Array.

The getItem() below must return dates as an Array.

public class Calendar implements Ownable {
    User owner;
    ArrayList<CalendarItem> Termin = new ArrayList<CalendarItem>();

    public Calendar (User owner){
        this.owner = owner; 
    }

    @Override
    public Person getOwner() {
        return owner;
    }
    public CalendarItem [] getItems(){
        return ; //  what should I return here?
    }
}

Actually your question is how to convert ArrayList to plain Array, isn't it? — kirilloid, Apr 24 '13 at 11:19
It's absolutely wrong to name variables in Java with capital letter. Stick to conventions! — eugen-fried, Apr 24 '13 at 11:20

Note - Termin is badly named, variables should all be in camel case.

public CalendarItem [] getItems(){
    return Termin.toArray(new CalendarItem[Termin.size()]);
}

See Convert ArrayList to String [] and toArray.

Try this:

public CalendarItem [] getItems(){
    return Termin.toArray(new CalendarItem[Termin.size()]);
}
