You can use something called Dash  Offline API Documentation for Mac  For Windows and Linux you have an alternative called Zeal    Both of them are very similar  And you can get offline documentation for most of the APIs out there like Java  android  Angular  HTML5 etc    almost everything   I have also written a post on How to install Zeal on Ubuntu 14 04

For any javadoc  not just the ones available for download  you can use the DownThemAll addon for Firefox with a suitable renaming mask  for example    subdirs   name   ext    https   addons mozilla org en-us firefox addon downthemall   https   www downthemall org main install-it downthemall-3-0-7   Edit  It s possible to use some older versions of the DownThemAll add-on with Pale Moon browser

JAVA Fax Api documentation  You could download the mac 2 2 preview release from here and unzip it   http   www oracle com technetwork java javafx downloads devpreview-1429449 html  The javadoc won t quite match 2 1  but it will be close and if you use the preview instead  it will match exactly   I think this would help you

update 2019-09-29  Java version 11  The technique below does not now work with Java 11  and probably higher versions  there is no way of ignoring multiple  broken links   i e  to other classes  other APIs   Solution  keep your javadoc executable file  or javadoc exe  from Java version 8     There are good reasons for making your own local javadocs  and it s not particularly difficult   First you need the source   At the time of writing the Java 8 JDK comes with a zip file called src zip   Sometimes  for unexplained reasons  Oracle don t always include the source   So for some older versions  and who knows about the future  you have to get hold of the Java source in another way   It s worth also being aware that  in the past  Oracle have sometimes included the source with the Linux version of the JDK  but not with the Windows one   I just unzipped this file    the top directories are  com    java    javax    launcher  and  org    Directory launcher contains no files to document   You can generate the javadocs very very simply from any or all of these by CD ing at the command prompt terminal to the directory     src   Then go  javadoc -d docs -Xmaxwarns 10 -Xmaxerrs 10 -Xdoclint none -sourcepath   -subpackages java javax org com   NB note that there is a     after -sourcepath  Simple as that   Generating your own javadocs also has 2 huge advantages    you know they are precisely the right javadocs for the JDK  or any exernal jar file  you are using on your system  once you get into the habit  reconstituting your Javadocs is not a tiresome challenge  i e  where to go looking for them    For example I just unzipped a couple of source jars whose packages are closely coupled  so their sources were in effect  merged   amp  then made a single Javadoc from them        NB Swing is semi-officially DEAD   We should all be switching to JavaFX  which is helpfully bundled with Java 8 JDK  but in its own source file  javafx-src zip   Unzipped  this reveals 3  root  packages  com  javafx and netscape  wha     These should be manually moved over the to appropriate places under the unzipped src directory  including the JavaFX com sun packages under the Java com sun strcture    Compiling all these Javadoc files took my machine a non-negligible time  I d expect to see all the JavaFX source classes in with all the other source classes some time soon     BTW  the same thinking applies to documenting any and all Java jars  with source  which you use   However  all versions of most jars will be found with their documentation available for download at Maven Central http   search maven org     PS afterthought  using Eclipse and the  Gradle STS  plugin  the  New Gradle STS Project  wizard will create a gradle build file containing the line   include plugin   eclipse    This magically downloads the source jar with the executable jar  under GRADLE HOME  when you go     gradlew build    addendum 2020-01-13  if you have chosen not to include the Eclipse plugin in your build gradle  it would appear that you can go  with the selection on your project in the Project Explorer  Right-click Gradle --  Refresh Gradle Project to get Eclipse to download the source files        giving you an extra degree of certainty that you have got the right src and therefore the right javadoc for the dependency in question
