A new Java Student in need of help

Question

I am new to this Java language and while so far I have found it to be quite easy I have now come up against a program that is giving me some problems. Our teacher has given us this program that had a bunch of errors and we had to find them and also correct them. There were 20 errors to start and I have gotten it down to only 2 errors but I cannot figure out how to correct them. The teacher said to use whatever we could get our hands on to help us correct this code (internet, books, etc) so I figured that I would try this message board. This is my first post so could someone please give me a hand? Here is the code:
import java.util.*;
public class Names
public static void main(String args)
try
List list = createList(args);
Collections.sort(list);
Iterator i = list.iterator();
while (i.hasNext())
String s = (String) i.next();
system.out.println(s);
catch (Exception e)
System.out.printlnn("Exception"+ e.getMessage() "\n");
private static List createList(String args[]) throws Exception
List List;
if (args.length == 0 || argx(0).equals("ArrayList"))
list = ArrayList();
System.out.println("Using ArrayList");
else if (args[0].equals("LinkedList"))
list = new LinkedList();
system.out.println("Using LinkedList");
else if
throw new Exception
("invalid argument " + args[0] + ". Valid choices are ArrayList or LinkedList");
fillList(list);
return list;
private static void fillList (List list)
list.add("Jim");
list.add("Helen");
list.add("Jennifer");
list.add("Daniel");
list.add("Michelle");
and here are the 2 errors that I can't seem to figure out:
C:\$jg105\Names.java:24: ')' expected.
System.out.printlnn("Exception"+ e.getMessage() "\n");
^
C:\$jg105\Names.java:41: '(' expected.
else if
^
2 errors
Finished
any help will be appreciated thanks Bob
