In-Depth Information
The output from the program is shown here:
In this example, the inner class
Inner
computes various values from the array
nums
,
which is a member of
Outer
. As explained, an inner class has access to the members of
its enclosing class, so it is perfectly acceptable for
Inner
to access the
nums
array directly.
Of course, the opposite is not true. For example, it would not be possible for
analyze( )
to
invoke the
min( )
method directly, without creating an
Inner
object.
As mentioned, it is possible to nest a class within a block scope. Doing so simply creates
a localized class that is not known outside its block. The following example adapts the
ShowBits
class developed in
Try This 5-3
for use as a local class.
