Where are they used?

Prashant Chinchkar · Answer

core java is the fundamental for java that will be used in any java
technology without this no one can jump on any advance java technology.
Where as
advance java is specialisation in some domain , as someone in networking,web,DCOM,or data base handling.
And more over core java packages are always started with java.lang. where as advance java are always with
javax.servlet.
or in other words
"core java means "stand -alone" java application whereas advanced java means java application that run on
servers means these are the web application"
