Much of revolution started from 1.2 onwards with JFC event delegation model as earlier version of Java i.e 1.x was much popular for Servlets and Applets than anything else.
Java Printing API was one of the area that got improved from 1.2 onwards...
Do you know that Java Uses different Floating Point Standard than compared to Microsoft. Read the article here... You must know this...

J2SE 1.2 (December 8, 1998)
This and subsequent releases
through J2SE 5.0 were rebranded retrospectively Java 2 & version name
"J2SE" (Java 2 platform, Standard edition) replaced JDK to
distinguish the base platform from J2EE (java 2 platform, enterprise edition)
and J2ME (java 2 platform, micro edition).

Strictfp keyword
·
Reflection
·
Swing api integration into
the core classes
·
JVM equipped with a jit
compiler

An IDL implementation for
corba interoperability

an exception to encapsulate original lower-level exception)

Java web start
J2SE 5.0 (september 30, 2004)
tiger [originally numbered 1.5]
·
Generics: provides
compile-time (static) type safety for collections and eliminates the need for
most typecasts (type conversion). ( example: typed Collections, Set(<String>))
·
Metadata: also called
annotations; allows language constructs such as classes and methods to be
tagged with additional data, which can then be processed by metadata-aware
utilities.
·
Autoboxing/unboxing:
automatic conversions between primitive types (such as int) and primitive
wrapper classes (such as integer).
·
Enumerations: the enum
keyword creates a typesafe, ordered list of values (such as day.monday,
day.tuesday, etc.). Previously this could only be achieved by non-typesafe
constant integers or manually constructed classes (typesafe enum pattern).
·
Swing: new skinnable look
and feel, called synth.
·
Var args: the last
parameter of a method can now be declared using a type name followed by three
dots (e.g. Void drawtext(string... Lines)). In the calling code any number of
parameters of that type can be used and they are then placed in an array to
be passed to the method, or alternatively the calling code can pass an array
of that type. Another example: printf() function, allows variable number of different arguments.
·
Enhanced for each loop:
the for loop syntax is extended with special syntax for iterating over each
member of either an array or any iterable, such as the standard collection
classesfix the previously broken semantics of the java memory model, which
defines how threads interact through memory.
·
Automatic stub generation
for rmi objects.
·
Static imports concurrency
utilities in package java.util.concurrent.
·
Scanner class for parsing
data from various input streams and buffers.
·
Assertions
·
StringBuilder class (in
java.lang package)
·

february and june 2006, leading up to a final release that occurred on
december 11, 2006. The current revision is update 20.

usability.

set of javascript functions to ease the deployment of applets and java web
start applications.

Features and Enhancements JDK
Documentation
Java Platform, Standard Edition 6 is a major feature release. The following list highlights many of the significant features and enhancements in Java SE 6 since the prior major release, J2SE 5.0. It is followed by a detailed table with links to related bugs, enhancements, and JSRs. Note, this web page relates to the Release Candidate milestone for Java SE 6. Its related Umbrella JSR 270 does not itself define specific features. Instead it enumerates features defined in other JSRs or through the concurrent maintenance review of the Java SE platform specification. The final release is expected to include all JSR 270 features, although it is possible for an approved feature to be dropped.
