if(con== null){ 
System.out.println("Not Connected to DataBase"); 
return; 
} 
DatabaseMetaData dm = con.getMetaData();
String pn = dm.getDatabaseProductName(); 
String pv = dm.getDatabaseProductVersion(); 
System.out.println("Connected to : "+pn); 
System.out.println("Version of DataBase is : "+pv);
