NAMING.PKG

Use lower case letters for "package" names

Description

This rule flags any "package" name that does not use lower case letters.

Package names should begin with a lower case letter. This prevents the possibility of mistaking a package name for a class name. In fact, package names should usually consist of only lower case letters.

Example

 package NAMING;    // violation
 
 public class PKG {
 }

Repair

Change upper case letters to lower case letters.

 package naming;
 
 public class PKG {
 }
