Official Java document index and official java Index

Official Java document index and official java Index

I have always felt that the official Java documentation is a little messy. Recently I have made some special preparations for reference only.

Portal

Oracle official documentation Portal: http://docs.oracle.com /. Only documents of JavaEE and JavaSE are organized on the lower-level pages.

JavaEE

JavaEE document Portal: http://docs.oracle.com/javaee /. The lower-level pages contain JavaEE-related APIs and Tutorial documents:

• Http://docs.oracle.com/javaee/7/api/
• Http://docs.oracle.com/javaee/7/tutorial/

JavaSE

JavaSE document Portal: External /. Subordinate pages:

• Http://docs.oracle.com/javase/specs/
• Http://docs.oracle.com/javase/tutorial/

There are also documents of specific versions. We will only look at the documents of JavaSE 8 later,

• Http://docs.oracle.com/javase/6/docs/
• Http://docs.oracle.com/javase/7/docs/
• Http://docs.oracle.com/javase/8/docs/

Javase/8/docs/

There are three subordinate pages,

• Http://docs.oracle.com/javase/8/docs/api/
• Http://docs.oracle.com/javase/8/docs/technotes/tools/
• Http://docs.oracle.com/javase/8/docs/technotes/guides/

Tools introduces JDK-related tools, which are divided into two subordinate pages by platform,

• Http://docs.oracle.com/javase/8/docs/technotes/tools/unix/
• Http://docs.oracle.com/javase/8/docs/technotes/tools/windows/

Guides introduces some technical points of JavaSE, such as rmi, jpda, jvmti, attach, and jvm.

• Http://docs.oracle.com/javase/8/docs/technotes/guides/rmi
• Http://docs.oracle.com/javase/8/docs/technotes/guides/jpda/
• Http://docs.oracle.com/javase/8/docs/technotes/guides/jvmti/
• Http://docs.oracle.com/javase/8/docs/technotes/guides/attach/
• Http://docs.oracle.com/javase/8/docs/technotes/guides/vm/

There is another portal,

• Description of Java Conceptual digoal

Technotes/guides/vm/

There are still too few materials in this JVM-related document. Then I searched two pages from OTN,

• Java SE at a Glance
• Java SE HotSpot at a Glance

Find the entry to the HotSpotVM documentation.

Of course, if you want to find the HotSpotVM documentation, you must get the OpenJDK homepage. There are two main portals,

• Http://openjdk.java.net/groups/hotspot/
• Https://wiki.openjdk.java.net/display/HotSpot/Main

VM Options

Two other documents related to virtual machine options are provided to facilitate query during use.

• Http://www.oracle.com/technetwork/java/javase/tech/vmoptions-jsp-140102.html
• Http://docs.oracle.com/javase/8/docs/technotes/tools/unix/java.html#CBBIJCHG

There are so many official documents that you don't have to buy any more books to chew on. ^_^
