Java Versions & Code Names
Most versions of the Java 2 Platform Standard Edition have an
internal code or project name.
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.)
