Please don't use bold red letters like that. It makes your post hard to read.

Also, it pays to ShowSomeEffort(←click). If you google for java collections tutorial you'll find explanations and examples, and the javadocs for those classes to a good job of explaning their respective purposes.
It is sorta covered in the JavaRanch Style Guide.
