 This is the java version of the Args program described in: http://butunclebob.com/ArticleS.UncleBob.CleanCodeArgs

 Schema:
  - char    - Boolean arg.
  - char*   - String arg.
  - char#   - Integer arg.
  - char##  - double arg.
  - char[*] - one element of a string array.
 
-Example schema: (f,s*,n#,a##,p[*])
-Coresponding command line: "-f -s Bob -n 1 -a 3.2 -p e1 -p e2 -p e3
+Example schema: (f,p#,s*,n#,a##,d[*])
+Corresponding command line: "-f -s Bob -n 1 -a 3.2 -p 22 -d /home/users/
+
+Code documentation updated
+
+Edited the main to add the schema for what all arguments types.
+Added help function and can be used by -h option when running the program.
+
+For Boolean type
+-Doesnt need a value(you just have to specify the argument name)
+-Only flag is enough to change to true
+
+Added double and string array code for parsing
 
+String array and map updated to take the value as argument
