WHAT IS CORE JAVA AND ADVANCED JAVA?
Firstly, there is no such concept like core java and advanced java. It is mainly created by the coaching centers to make their terminology easier. Java mainly consists of three parts j2se, j2ee &j2me.
1) J2SE (Java2 Standard Edition)
3) J2ME (Java2 Micro/Mobile Edition)
Here j2se deals with the fundamental parts of the java like oops concepts and their implementation in the language, which is termed as core java and whereas the rest of the two parts are considered as advanced java.
Core java is standalone java application, whereas advanced java deals with server side applications.
Without proper knowledge of core java, no one can jump on to learn advanced java.
