This is the general method, you'll need to use a fully qualified class name.

myInstance.myMethod (Class.forName("fully.qualified.ClassName"));

Use static method of Class class 

 yourMethod(other arguments,..., Class.forName("name of your class in string Formate.."));

this method return a Class class object for your class...

You can use reflection:

String className = "goo";
Class c = Class.forName(className);
foo(c);

try this:

 Class.forName("Foo")

but the corresponding class must be in the classpath.
