What is fully-qualified class name

When people use the term fully-qualified class name in the Java world, they mean the class name with its package name prepended.

For example if I had the class HelloWorld:

Class: HelloWorld
Package: com.blogger.nofoe
Fully-qualified name: com.blogger.nofoe.HelloWorld


Note: The naming convention for packages in java goes {domain extension}.{domain name}.{project name}
