Introduction
“Emerging Technology always needs emerging based on customer
satisfaction, better quality product with other non-functional
features.
The purpose of this white paper is for FYI to show what are the new features introduced in latest version of
java & .net, and what were the problem/challenges, how to resolved those problem.
How much they impact on projects and business?
Herewith I’ll go through the java features.

Challenges / Opportunities
• Some challenges in growing IT industry
– Access control over the public class
– Untouched APIs
4

5. 2009© Symphony Services Corp. | Proprietary & Confidential
Proposed Solution
– Access control over the public class - superpackage (only in Java)
– Untouched APIs - java Kernel (only in Java)

superpackage
• Extend the access control model defined by the JLS and
JVMS to accommodate projects larger than a single
JAVA package
• The extensions to the access control mechanisms
should be simple and consistent with the new proposed
model.
• The loses the benefits of information hiding will rectify
by superpackages.
• Unlike packages, superpackages are explicitly declared
in a JAVA source file.

Realized Benefits of superpackage
• For practical purposes, attempting to access a non-
exported class from outside its defining superpackage
will result in the same behavior that is observed today
when attempting to access a private class from outside
its defining package
• Public types can be declared as exported to make them
accessible outside the superpackage
• Public types in a superpackage that are not exported
are accessible only to other types in the superpackage
• A type can be a member of at most one superpackage

Example-1 for superpackage
• // Declare the superpackage
superpackage example.foo.myapp
{
// all types in the listed packages are members of this superpackage
member package example.foo.myapp.ui;
member package example.foo.myapp.processing;
// list of exported types
export example.foo.myapp.Main;
export example.foo.myapp.Helper;
}
File example/foo/myapp/ui/Main.java
package example.foo.myapp.ui;
public class Main
{
public Main() { ... }
}
File example/foo/myapp/ui/Parser.java
package example.foo.myapp.ui;
public class Parser
{
public Parser() { ... }
}

Example-2 for superpackage
super-package.java
superpackage com.myorg.myApp.ui
{
member package com.myorg.myApp.ui.swing;
member package com.myorg.myApp.ui.html;
}
super-package.java
superpackage com.myorg.myApp.model
{
member package com.myorg.myApp.model.swing;
member package com.myorg.myApp.model.html;
}
super-package.java
super package superpackage com.myorg.myApp
{
member superpackage com.myorg.myApp.ui;
member superpackage com.myorg.myApp.model;
}

Java Kernel
The idea is to create a 'minimal' JRE which has enough
code to run System.out.println("Hello world!").
Implement JAVA as a small kernel, then load the rest of
the platform and libraries as needed.
The kernel JRE is currently divided into a hundred or so
different bundles(package boundaries).
If you touch any class in java.rmi, the entire java.rmi
package will be downloaded.
Some bundles involve more than one package i.e.
javax.swing with java.swing.event and other package.

Realized Benefits of Java Kernel
Goal of Java Kernel -
• reducing startup time
• memory footprint
• installation
• solve the JRE deployment and performance issues
• user doesn't have to wait for a large JRE download
• needed program are downloaded in the background

Some other features

Critical Trends
13
• The JAVA and .NET technology cover a great deal of
technologies and standards
• 80% of large mainstream IT organizations rely on
both .NET and JAVA technologies
• Costing to company
• Skill and infrastructure available
• Clients requirement

Summary
14
Each and every day companies enhances product, features,
easiness, better look-and-feel, based on client requirement,
market requirement, competition, that means “emerging
technology needs emerging always”.
