how do you implement static block in framework code example

Example: how do you implement static block in framework

Static Block:
I use static block in DBUtilities class. See below...

 		static {
            try {  
         connection = DriverManager.getConnection(url, username, password); 
         statement = connection.createStatement();
         metadata = connection.getMetaData();
            }catch(Exception e) { }
             e.printStackTrace();
        } 

And I also use static block in ConfigurationReader 
class. By using static block, as soon as 
Configuration class is loaded I will be
able to get the path and connect to the
properties file, ready to retrieve the 
desired value from properties file using get method.
