Declaration Guidelines for Source Files
As  the  last  piece  of  this  area  how  about  we  now  investigate  the  source  file  declaration
standards.  These  tenets  are  key  when  declaring  classes,  importing  declarations  and
packages in a source file.
There can be stand out public class for every source record.
A source document can have numerous non public classes.
The public class name ought to be the name of the source document. The name of
the source file must be affixed by the string .java. For instance, the class name is
public  class  Employeerecord{},  then  the  source  document  ought  to  be  saved  as
Employeerecord.java.
If the class is declared inside a package, then the package articulation ought to be
the first proclamation in the source record.
If  import  articulations  are  available,  then  they  must  be  composed  between  the
package proclamation and the class revelation. On the off chance that there are no
package proclamations, then the import articulation ought to be the first line in the
source file.
Import and package articulations will intimate to all the classes show in the source
record. It is impractical to announce diverse import and/or package explanations to
distinctive classes in the source file.
Classes  have  a  few  access  levels.  Moreover,  there  are  diverse  sorts  of  classes,  which
include  final  classes,  in  addition  to  several  others.  Separated  from  the  aforementioned

sorts  of  classes,  Java  likewise  has  some  uncommon  classes  called  Inner  classes  and
Anonymous classes.
