Invoke Apex Classes
Once apex class is compiled and saved then you can invoke apex class method by creating object of class or direct invocation of static members.
Note: Class is blue print for object.
Ways/where to invoke or refer apex classes:
a) Using another apex code ( Apex class / Trigger / Apex Anonymous code block)
b) Visualforce Page using {!actions}
c) JavaScript Remoting Requests ( with in visualforce pages ) ( used for AJAX calls )
d) SFDC API calls ( external Program connecting through REST/SOAP APIs). ( Java / JavaScript / VC++/ VB++/ Perl etc. ) ( define apex methods with webservice ,global and static keywords )
