Dynamic loading is a technique for programmatically
invoking the functions of a class loader at run time.
Let us look at how to load classes dynamically.
Class.forName (String className); //static method which
returns a Class
The above static method returns the class object associated
with the class name.
The string className can be supplied dynamically at run
time.
Once the class is dynamically loaded the following method
returns an instance of the loaded class. It’s just like
creating a class object with no
arguments.
class.newInstance (); //A non-static method, which creates
an instance of a
//class (i.e. creates an object).
Example as shown below ....
Test test = null ;
String myClassName = "com.test.DynamicLoadingClass" ;
Class testClass = Class.forName(myClassName) ;
test = (Test) testClass.newInstance();

String varible is taken as an object in java, which is
created with out new operater.
