The difference is the one between static and non-static. Any tutorial or the JLs will clarify the difference, no need to repeat it here.

It's usually not like you have much of a choice. If you need access to an instance's attributes, you can't make it static. Otherwise, make it static.

If the utility method will not depend on the value of a particular instance, and will not need to access the value of a particular instance (i.e. non-static data member), it would make sense to make that method static.

Then the functionality you will be offering will conceptually belong to the class, not instances of that class. Think java.lang.Math, for example.
