If you'd like to better introduce yourself to the subjects of Java and computer programming, do the following activities:
Visit Sun's official Java site at http://java.sun.com/java2/whatis and read the company's introduction to the Java technology.
Using English sentences instead of a programming language, write a set of instructions to add 10 to a number selected by a user and then multiply the result by 5. Break the instructions into as many short one-sentence lines as you can.
To see solutions to the activities at the end of each hour, visit the book's Web site at http://www.java24hours.com.
