latest version of jdk

[Kalyani Nayak]

Can anyboy tell me features of jdk1.7(dolphin) over jdk1.4(tiger)

[Jeroen T Wenting]

no.
Dolphin doesn't yet exist, Tiger isn't 1.4, and 1.4 isn't the latest version.

[Jesper de Jong]

Tiger is the current production version of Java - Java 1.5 (or 5.0, that's the same).

The next version, which is due to get ready in a few months, is Java 1.6 (or 6.0...), codenamed Mustang.

After that we'll have Dolphin (1.7, 7.0, ...) but it will probably be two years or so before it's ready for release.

See http://java.net/ for info on future Java releases.

[Jeroen T Wenting]

technically 1.5 doesn't exist.
It's the internal version number for the files, not the version for the entire product.

So javac 1.5.0 is part of JDK 5.0.

Thank you, Jesper: your helpfulness is very much appreciated by the staff.

[Jesper de Jong]

If you want to know why Sun likes to confuse us with different version numbers for the same thing, see this: Version 1.5.0 or 5.0?

[Jeroen T Wenting]

at least we're no longer bothered with the Java 2 standard edition 1.4 version 1.4.2_08

[dema rogatkin]

So what features we should expect in 1.7? Templates, operator overloading, macro processing?

[Ernest Friedman-Hill]

I'm looking forward to

java.lang.AI.dwim();

There was an announcement at JavaOne last week about that. Nothing substantial yet; all I see in the various on-line reports is this, which appears to be straight from the press release:

"The Dolphin release, also known as Java SE 7, is set to feature direct support for XML and �super packages�, which are new constructs that allow hierarchical modular organization. Super packages are expected to benefit larger scale development."

(After a little more googling:) Here's a link with a tiny bit more detail:

Templates - do you mean like C++ templates? Did you know Java 5.0 already has generics, which is more or less the same?

What about some of the neat features of C# - delegates, getters and setters? (No pointers and no operator overloading, please!)

oh god, they're going to change the language syntax to XML?
Don't hope we're going to have to code something like:

<java-class>
<package>com.somecompany.somepackage</package>
<imports>
  <import>java.util.*</import>
  <import>javax.servlet.*</import>
</imports>
<class-name>SomeClass</class-name>
<inherits>AnotherClass</inherits>
<implements>Interface1</implements>
<implements>Interface2</implements>
<members>
  <member name="int1" type="int"/>
</members>
<constructor>
  <arg type="int" name="anInt">
  <throws>AnException</throws>
  <code><[CDATA[int1 = anInt;]]/></code>
</constructor>
<method name="getInt1" returns="int">
  <params/>
  <code><[CDATA[return int1]]/></code>
</method>
</java-class>

in the future (I've seen things like this proposed, don't think I made it up on the spot)...
