Programming From Scott Orgera, your About Programming Editor June's first newsletter is a diverse one, focusing on Java, JavaScript, Perl, PHP, C#, VB.NET, and more... JavaScript Variables, Functions, Properties and Methods These four terms are all used in referencing various parts of the code when you are writing a program or script. Each of them has a particular meaning and in many programming languages the distinction between them is important. With the way JavaScript works though the distinction between these terms is not as great as it is in many other languages.

So if you know that 0 + 1 = 1 then you know the first three numbers are 0, 1, and 1. To get the fourth number, you add together the second and third. So 1 + 1 = 2. The fourth number is two. The fifth number is the addition of the third and forth, or 1 + 2 = 3. Getting the hang of it? Great, because now we are going to write a simple PHP program to calculate numbers in the Fibonacci sequence.

For example, when you define a method you can pass it parameter values of a certain type. The parameters can be different values that all belong to that type. Generics follows the same sort of thinking except that what is being defined it the type itself.

The JNLP API allows an unsigned application, which will be running in the sandbox due to security restrictions, access to the user's machine as long as the user has given permission. For example, the application won't be able to see what's on the user's local drive but it can pop-up dialogs that allow the user to pick a file which the application can open.
