Basic Question - IDE and Package/Import

[shadders]

Hi,

Apologies for this very basic question.

I am working through the java book for v6, and the book supplies netbeans IDE but only uses the jdk from Sun at the command line.

I have created a class in a file with the java extension.

I wish to use the class in an application.

How do i reference this class or file, to use the class in the application ?

1. I have copied the java file to the src directory in the IDE but this does not work.
2. I added the java class file to the library in the IDE and this did not work.
3. i have checked the help file - could not find the relevant section.
4. i used the library manager - added as a library and source - still did not work.
5. (Note added 18/5/2012) - i have followed the tutorial on this web site - added the JAR to the project in the library - and this does not work - so i am missing something basic or obvious ?.

I suppose i do not know if i use "import" or "package" keyword - since i am new to java.

I know how to accomplish in C/C++/C#, but no java.

If anyone can provide guidance on this basic issue - i would be most grateful.

Thanks and regards,

Richard.
