Syntex:  Here is the syntax that must be followed by a developer whenever defining a package.

Note: Here are some points that must be considered while declaring and defining a package.

• In java programming language while defining a package then the package statement, must be the first non-comment statement in Java source file. For example the above syntax have a fully-qualified class name of the MyClass i.e com.roseindia.MyClass.
