Count uncommented, blank and source lines in perl

Hi friends, I am working on a perl script to count the commented lines, blank lines and source lines separately. Let me know if you have one. For example i have a file containing the lines:
Code:
 /**
 * SOURCE CODE
 */
 
public class SessionConstants {
  /**
   * Code for Session created
   */
public final static int CREATED_CODE = 0;
 
  /**
   * Constants defining the Session type
   */
  public enum SessionType {
    DC_SES, LC_SES, SM_SES
  }
}

The script should read the file and count the Commented lines(/* */), blank lines and actual source lines. The expected output should be, Commented lines=9, Blank lines=2, Source Lines=6. Thanks in advance.

GIT-STRIPSPACE(1)						    Git Manual							 GIT-STRIPSPACE(1)

NAME
git-stripspace - Remove unnecessary whitespace SYNOPSIS
git stripspace [-s | --strip-comments] git stripspace [-c | --comment-lines] DESCRIPTION
Read text, such as commit messages, notes, tags and branch descriptions, from the standard input and clean it in the manner used by Git. With no arguments, this will: o remove trailing whitespace from all lines o collapse multiple consecutive empty lines into one empty line o remove empty lines from the beginning and end of the input o add a missing to the last line if necessary. In the case where the input consists entirely of whitespace characters, no output will be produced. NOTE: This is intended for cleaning metadata, prefer the --whitespace=fix mode of git-apply(1) for correcting whitespace of patches or files in the repository. OPTIONS
-s, --strip-comments Skip and remove all lines starting with comment character (default #). -c, --comment-lines Prepend comment character and blank to each line. Lines will automatically be terminated with a newline. On empty lines, only the comment character will be prepended. EXAMPLES
Given the following noisy input with $ indicating the end of a line: |A brief introduction $ | $ |$ |A new paragraph$ |# with a commented-out line $ |explaining lots of stuff.$ |$ |# An old paragraph, also commented-out. $ | $ |The end.$ | $ Use git stripspace with no arguments to obtain: |A brief introduction$ |$ |A new paragraph$ |# with a commented-out line$ |explaining lots of stuff.$ |$ |# An old paragraph, also commented-out.$ |$ |The end.$ Use git stripspace --strip-comments to obtain: |A brief introduction$ |$ |A new paragraph$ |explaining lots of stuff.$ |$ |The end.$ GIT
