The difference between Core Java and Advance Java is that in
Core Java we only use the basics of Java Language such as
java console programming, control statements, array,classes,
objects ect. It is all about to understand the fundamental
of Java Programming. In Advance Java we use more inbuilt
tools and classes. These are used by the programmer without
go in to detail how its work and execute. But a programmer
who has the knowledge of core java can actually understand
the background working of advance java tools and inbuilt
programs

How a programmer confirm if there is any problem with the program he wrote for insertion... ANS:--- >executeupdate method is having boolean return type, if anything goes wrong in data insertion or data updation, it would return false. otherwise, if it successfully inserts data into the database, it would return true NOW HOW TO I CHECK IN MY DURING EXECUTION WHETHER IT RETURNS TRUE OR FALSE... WELL IT WILL DISPLAY ANY MESSAGE OR NOT
