Answer / puneet
package is just a namespace under which the
classes,interfaces are kept and they on the filesystem where
the application is running are just a folder and maintains
the files anf folders and help us to implement the
inheritance stuff and you can have 2 files with the same
name in two different packages which should clash, you can
call the class with full name packagage1.classname
Note Web-inf folders,Lib folders are not packages.
java.lang, java.util,java.io;
