Collections

[Jon Camilleri]

For example, suppose you want to let some part of your code look at, but not touch, the
contents of a collection. Here is what you could do:
List<String> staff = new LinkedList<String>();
. . .
lookAt(new Collections.unmodifiableList(staff));

Core Java Vol.I (8th Ed) P.695

How do I call lookAt?

[Jesper de Jong]

unmodifiableList is a static method of class Collections. Don't use the new keyword:

lookAt(Collections.unmodifiableList(staff));

I can't find any documentation here.

[Seetharaman Venkatasamy]

java.util.Collections is a utility class for other collection classes.you cant instantiate, it has only private constructor

[Rob Spoor]

It's a static method. Surely you know how these work?
