Question: I have never understood what is the ideal way to name a project, package, class. I do it in a random way which doesn't look professional at all. I know the class name should start with a capital alphabet. But what I don't really have trouble with is finding the names that are suitable and look professional. lets consider this example. If I am writing a program for fibonacci series i give names like this:

```
project name = fibonacci_project
package name = org.fib.code1
class name = Code1

```

Doesn't look neat right? How would you do it ?

Answer: 
For starters, it's [Fibonacci](http://en.wikipedia.org/wiki/Fibonacci_number).

See [Sun's java naming conventions](http://java.sun.com/docs/codeconv/html/CodeConventions.doc8.html) for some details on package / class names.

Aside from that, the general rule of thumb is - all your names should be descriptive:

* for class - what does it do (or what does it represent)
* for package - what common functionality (goal) do all classes within that package provide (aim to achieve)
Your class name should always start with Uppercase.
your package name should always start with lowercase.
and your method name inside the class should also start with the lowercase.
