Join David Gassner for an in-depth discussion in this video Using the Java API documentation, part of Java 7 Essential Training.
- When you're learning Java…you'll need access to the documentation.…You need to learn the core of the language,…its basic syntax,…but a lot of working with Java…is about working with the runtime library,…the set of packages and classes…that are provided with the JRE and the JDK.…You can get to a certain amount of documentation…from within IntelliJ IDEA very simply.…For example, if you want to learn about a particular class,…you can click into the class name…and then press a keyboard shortcut…to bring up the quick documentation.…
It's CTRL+Q on Windows,…and CTRL+J on Mac.…That opens up a version of the documentation…that will tell you the most important…things about the class.…But it won't tell you all of the details.…I will point out that if you want to increase…the size of the font in this window,…click on the gear icon, and you can drag…to increase or decrease it.…In order to get to the full documentation,…you'll either need to get to it on the Web…or by downloading it from Oracle…and installing it locally.…
I prefer getting it from the Web.…
