  Bug ID: 4926251 instance variable initializers in named classes can throw checked exceptions
�An instance initializer of a named class may not throw a checked exception unless that exception or one of its superclasses is explicitly declared in the throws clause of each constructor of its class and the class has at least one explicitly declared constructor.
In this case that would have been specifying that instance variable initializers for named classes can throw any checked exception as long as it is named in the throws clause of every constructor in the class (the same rule as is applied to instance initialization blocks).
Thus adding checked exceptions thrown in instance variable initializers and instance initialization blocks to the throws clause of every constructor in the class is an obvious means of documenting that instantiating the class (i.e., evaluating a class instance creation expression) throws checked exceptions above and beyond what the constructor throws.

 The Essence of OOP using Java, Instance Initializers
The code in an instance initializer block is executed after the constructor for the superclass is executed, and before the constructor for the class to which the initializer belongs is executed.
Two separate instances (objects) of the class named B are created, showing not only the order in which the instance initializers and the constructors are executed, but also showing that the static initializers are executed one time only when the classes are first loaded.
Each time an object of the class named B is instantiated, an instance method of the class is invoked to display the values of the instance variables initialized during the process of instantiating the object.

Preventing a second instance, then, requires you to use some global mechanism to detect that an instance of the application is already running.
If an instance of the application is already running when that happens, you should bring the application to the top and load the file the user double-clicked.
In order to pass data from the second instance of the application to the first instance, you must implement some type of shared memory scheme.

 Tutorial # 2: Examples of Instance Hierarchy
These 'empty instances' can be thought of as normal instances but without any corresponding geometry; they are used as building blocks to connect parts of a hierarchy tree together.
This tree is created by adding two empty instances to the scene using the command, creating instances of the box and sphere objects with the command, then attaching the new instances together in a tree structure using the command.
Note that objects and their derived instances do not share the same transformation matrix, but rather they have their own copy (however, when an instance is first derived from an object its transformation matrix is copied from the master object).

An instance is a special copy of the dungeon for you and your party.
When a player logs out in an instance dungeon and that instance resets, the player will be moved to the zone-in area they used to enter the dungeon.
The person can then "zone in" (enter) the instance and be in copy B. After a player joins a group, the new group can summon the player (Warlock and 2 players required) into the instance.

 Copying an Instance   (Site not responding. Last check: 2007-10-07)
You can make a copy of an instance from a list control or a graph control and paste it into the same control or any other control which will accept an instance of that class.
Copying an instance causes a new instance to be created which is thereafter unrelated to the original instance.
For example if instance A refers to instance B then a copy of A will refer to a copy of B. Thus a single instance copy operation may cause the system to generate many new instances because all referenced instances must be copied.

 Adding a second Postfix instance | Advosys Consulting
That instance accepts mail on a separate IP address, and has separate versions of main.cf, master.cf, maps and a separate spool directory.
Working with the inbound and outbound instances is easier if you create similar "second instance" shell scripts for commonly used commands such as "postconf", "postfix flush" and "postfix reload".
Each instance has it's own main.cf and other files, so you are free to customize one instance without affecting the other.

 Instance Variables
Each instance-variable-clause declares a number of instance variables for instances of the class, or expressions to be evaluated when an instance of the class is created.
Generation -- Each instance variable declaration is either a new variable definition (potentially overriding a definition in a superclass) or a reference to an existing variable in a superclass.
instance variables, the inherited-variable or external-inherited-variable specifies a (public) instance variable from the superclass.

In partial support of this it might be noted that the use of the word "original" in a positive sense to refer to 'authored' texts, paintings, etc., did not occur until the late eighteenth century, not long after, for instance, the emergence of the idea that individual actors might give their own interpretations of roles.

 PRODUCT REVIEW: -- XML Instance 1.1 --
I have found the speed of XML Instance to be adequate on a 366Mhz, Win95 machine, but nonetheless notably slower than a native compiled application (especially during startup).
What this gets you is a way to look at long documents and have a good sense of their overall contents, but still zoom into the details where needed; it works in much the manner of folding in a text editor, which is something I find greatly useful.
Unfortunately, there is not much more to XML Instance than I have described, at least in terms of creating and editing a document.

 Specifying the Instance Name   (Site not responding. Last check: 2007-10-07)
Since the instance name is used for several objects, and the database names are a concatenation of the instance name and "NSMain" or the application name, it is best to keep the instance name short, and to name the instance based on unchanging entities.
For example, you might want to name the instance according to a target audience, a functional unit of your company, or a product.
It is best to avoid using the names of organization units (which can change frequently), an application, or the server on which the instance is running.

At this point, the first instance of the application will come up whenever a user tries to create a new instance.
Many times new instance launching happens from the Windows Explorer when the user opens a file with an extension that is registered for your app.

 Annoyances.org - re: XP calculator multiple instance annoying (Windows XP Discussion Forum)   (Site not responding. Last check: 2007-10-07)
I use the calculator a lot to do Hex to Decimal conversions, to help me do calculations faster, I have a hot key(one of those "enhance" key) on a windows egonomic keyboard to execute calc.exe, so that everytime I need the calculator, I just hit the key and it will come up.
But now that Windows XP make it multi-instance, everytime I hit the hot key, it will bring up a new program, which is annoying to me and it is also a waste of time.
Why would someone need multiple instance of a calculator running, for me it makes more sense that there should at least be an easy way to control whether a program is single instance or multi-instance.
