Manipulating Objects
Software development tools,
such as GUI builders and debuggers,
need to manipulate objects at run time.
For example, a GUI builder may
allow the end-user
to select a Button from a menu of components,
create the Button object,
and then click the Button
while running the application within the GUI builder.
If you're in the business of creating
software development tools,
you'll want to take advantage of the
reflection API features described in this lesson.
How can you create an object if you don't know its
class name until run time?
You'll find the answer in this section.
In this section you'll learn how to get the values of
an object's fields, even if you don't know the name
of the object, or even its class, until run time.
Not only can you get field values at run time, you
can also set them. This section shows you how.
This section shows you how to dynamically invoke methods.
Given an object, you can
find out what methods its class defines,
and then invoke the methods.
