Question about java Collections

[Steve High]

Hi.
I never worked with java's built-in collections framework, and I'm
having a bit of trouble with it.
I'm trying to pass a simple char data type into a
java.util.LinkedList, and I continue to get an incompatible type
exception (because it's expecting type Object). Is there a way I can
cast the char or set up the list so I can avoid this? I really dont
want to write a LinkedList class if one already exists.

BTW, I'm using the NetBeans IDE from the Sun website, if that means
anything.

Thanks.

Use the Character class in the java.lang package to wrap the char
prinmitive data before adding it the the Collection

You should also note that when you retrieve your data from the linked,
it will come in the form of a generic Object. You need to cast it back
to Character in order to extract your data from it.

Nice thing is that with autoboxing facility to be introduced in JDK1.5
such painfully redundant syntax are eliminated.
