How do you read JavaDoc? [closed]

JavaDoc jar can be unzipped directly. In theory any released javadocs can be downloaded and viewed offline.

1. download directly from maven repository. For example: http://central.maven.org/maven2/com/googlecode/objectify/objectify/5.0.3/objectify-5.0.3-javadoc.jar

2. Now you get objectify-5.0.3-javadoc.jar, rename the file to objectify-5.0.3-javadoc.zip

3. use your favourite unzip tool to extract it, now you have a folder objectify-5.0.3-javadoc

4. double click index.html will open the index page on your default browser.
