After downloading the external jar package, link the source code and Javadoc.jar

Today, we have downloaded a jar package from Apache Common and have a new understanding of the introduction of the source code and the Javadoc, which is recorded here.

Binaries refers to a binary file that contains the jar package used. Source refers to the source code.

Xxx.tag.gz is a compressed package used under a Linux system, and Xxx.zip is used by Windows systems.

After downloading two zip packages,

Commons-collections4-4.1-bin.zip the folder under decompression

Where Commons-collections4-4.1.jar is a jar package that can be used. Commons-collections4-4.1-javadoc.jar is a javadoc that you can link to in eclipse.

Source attachment can be linked on Xxx-src.zip, which is the source code. After the link, click the call method, you can directly see the source code of the method, put the mouse on the method, you can see the detailed description of the method.

Javadoc location can be connected to the-javadoc.jar. After the link, put the mouse on the method, you can see the detailed description of the method, but can not see the source after the click.

A bit strange is that since the link source can see the detailed description, then also need-javadoc.jar what is the use?
