How to get the Visual Force Page Name Using Apex Class?

Hi,
In this post i am giving an example of how to know the current VF page name using apex class.

We can get the Visual Force Page Name Using Apex Class, below is the Example:

public string getVFPageName()  {
// THIS IS THE CLOSEST YOU CAN GET SO FAR
String pageName = ApexPages.CurrentPage().getUrl();  
// IT ALWAYS STARTS WITH /APEX/ SO REMOVE IT
pageName = pageName.replaceFirst('/apex/','');         
pageName = EncodingUtil.urlEncode(pageName, 'UTF-8');  
// %3F IS THE VALUE OF THE QUESTION MARK IN UTF-8 
string[] pageNameExtra = pageName.split('%3F',0);   
// SO YOU MAY SPLIT THE STRING AT THAT POINT
  // FOR THIS PURPOSE YOU ONLY NEED THE FIRST
// IN THE RESULTING ARRAY
pageName = pageNameExtra[0]; 
// HERE IS YOUR PRODUCT  
system.debug('pageName-->'+pageName);                       
return pageName;                                        
}
