Sams Teach Yourself Java 2 in 21 Days, Second Edition

Exercises

To extend your knowledge of the subjects covered today, try the following exercises:

• Use reflection to write a Java program that takes a class name as a command-line argument and checks whether it is an application—all applications have a main() method with public static as modifiers, void as a return type, and String[] as the only argument.

• Write a program that creates a new object using Class objects and the newInstance() method that serializes the object to disk.

Where applicable, exercise solutions are offered on the book's Web site at http://www.java21days.com.
