Copy the jar into your project lib folder. Then right click on your project select properties. Now a window opens go to libraries->Add Jar/Folder select your jar and press OK.

You can create new maven project and add:
<dependency>
<groupId>net.sf.opencsv</groupId>
<artifactId>opencsv</artifactId>
<version>2.0</version>
</dependency>
To Your pom file.
//edit: I suggested it because IMO NetBeans has great maven support, and it's probably the best solution for using external libs in NetBeans. How ever I'm not sure is it right way for beginners.

I will just add a little explanation why adding a jar file into the library works.
A jar file is actually just a zip file, on linux you can find out by this command:
file xml-apis.jar
# xml-apis.jar: Zip archive data, at least v1.0 to extract
There is a folder structure inside the jar file, you can list it with 7z:
7z l xml-apis.jar
The output in this case:
7-Zip [64] 9.20 Copyright (c) 1999-2010 Igor Pavlov 2010-11-18
p7zip Version 9.20 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,8 CPUs)
Listing archive: xml-apis.jar

2006-11-19 23:41:32 ..... 515 220 org/w3c/dom/DOMImplementation.class
Thus having added the jar file in the classpath, when you do this in your java source code:
import org.w3c.dom.DOMImplementation;
the DOMImplementation class can be found in the jar file in the directory org/w3c/dom.
