Please don't shout. Excessive use of capital letters is considered poor etiquette.

You use it when you don't want a class to be extended.

java.lang.String and the Number classes are final to prevent someone tinkering with them and making them behave in ways that are not expected. Other immutable classes are final to prevent people adding mutable behaviour.
