Think of a class at a template or prototype from which object instances are created. Java files are compiled into class files, and class files are loaded from disk (usually) by the JVM's classloader and cached, and those classes are used to create instances of objects. Also, you can typically think of object instances as having a relatively short life span. Objects are usually instantiated, used for some purpose, and typically left to be garbage collected when they have gone out of scope.
