Java Import jar Package

The new Java project, which wants to reference the methods in other jar packages, needs to introduce the. jar file into its own project.

For example:

Org.apache.commons.codec.binary.Base64;

1. Download the jar package.

http://commons.apache.org/proper/commons-codec/download_codec.cgi

Download

3. Create a new Lib directory under the Projec project.

3. Unzip the downloaded compressed package and copy the. jar file from the compressed package to the project's Lib directory.

3. Select Commons-codec-1.10.jar-> in the Lib directory right-click->build path, add to build path

4. If the jar package is added for the first time, the project will automatically add a directory referenced library and contains the jar package:

5. Right-click the project name->build Path, config build path can see the libraries inside can already appear the added jar package, OK!
