Java code names

Hi all,

I am back after a long time. Today I am writing about the Java code names which most of us don’t know about.

Java, one of the most popular object oriented programming language, was initially codenamed Oak. The first stable version was the JDK 1.0.2. is called Java 1.

Most versions of the Java 2 Platform Standard Edition have an internal code or project name, as listed below. The dates listed are the final product release dates (following any beta releases). Feature releases are shown in bold.

Starting with Tiger, each version has two version numbers: an internal number, such as 1.5.0, and an external number, such as 5.0.

Since 1.2.2, major releases 1.3, 1.4.0, 5.0 and 6) are named after birds or mammals, while minor releases are named after insects, given that they are bug-fix releases. (Hopper is short for grasshopper and ladybird is another term for ladybug.)

In his blog Mustang and Dolphin… we’ll miss you, Ray Gans has explained how the code names are left behind and developed a new project naming system around the open source model.
