    public class List
    extends Object
    implements TextElementArray
    A List contains several ListItems.

    Example 1:

     List list = new List(true, 20);
     list.add(new ListItem("First line"));
     list.add(new ListItem("The second line is longer to see what happens once the end of the line is reached. Will it start on a new line?"));
     list.add(new ListItem("Third line"));
     
    The result of this code looks like this:
    1. First line
    2. The second line is longer to see what happens once the end of the line is reached. Will it start on a new line?
    3. Third line
    Example 2:
     List overview = new List(false, 10);
     overview.add(new ListItem("This is an item"));
     overview.add("This is another item");
     
    The result of this code looks like this:
    • This is an item
    • This is another item
