How to import commons.apache.math libraries correctly for my own project

Question

I want to use the commons.apache.maths classes for my own project, but I do not know how to correctly import them into eclipse. I visited the download page for the above package http://commons.apache.org/math/download_math.cgi , but I don’t know if the jar file that I want to import is included, zip binaries or source zip files. First I tried the binaries, and when I do the import, I just get a list of empty packages. Can someone who knows how to make the right import please show me how to do this?

What I'm doing at the moment, I download the zip file from the link above, extracting it, and then right-click my project-> properties-> Java Build Path-> Libraries-> Add External Jars. My problem is that I don’t know which banks to add.

Thanks in advance. Arlind

Answer 1

You need to import this path.

import org.apache.commons.math 

You can add the zip file to your build path or extract the jar files from the zip and add it to the build path. For example, to add 2.1 apache math, you need this commons-math-2.1.zip zip file or extract commons-math-2.1.jar from the zip file and add it to the eclipse build path.

Another trick is if you have jar or zip files added to your build path in eclipse then do ctrl + shift + o and eclipse will automatically import the packages for you.

Answer 2

There is commons-math-2.1.jar - add this to your project

Answer 3

download the jar file, extract it locally. Open eclipse, project-property-java build path-libraries-add library, where you added the extracted folder there. then you can use the org.apache.commons.math3 import.
