The following is a very good site for learning
the Java Language
and many of its concepts .
http://java.sun.com/docs/books/tutorial/java/index.html
When viewing this site make note of the following:
1...We are running in a Jbuilder environment and utilizing
many of the JOptionPane methods ti facilitate
input and output
--- example we will not use "System.out.println("hrllo
world");
2...We are placing our code in the constructor method of our class
while some of their examples place the code in
the "main
method". Applications will run either
way.
