  Constructor (Java 2 Platform SE v1.4.2)
The hashcode is the same as the hashcode for the underlying constructor's declaring class name.
The string is formatted as the constructor access modifiers, if any, followed by the fully-qualified name of the declaring class, followed by a parenthesized, comma-separated list of the constructor's formal parameter types.
- array of objects to be passed as arguments to the constructor call; values of primitive types are wrapped in a wrapper object of the appropriate type (e.g.

 Constructor Failures (or, The Objects That Never Were)
In the C constructor, say you want to catch an exception thrown from the constructor of a base subobject (such as A) or a member object (such as b_).
For a constructor to have an empty throw-specification, all base and member subobjects must be known to never throw, whether they have throw-specifications that say so or not.
Constructor function try blocks are useful only to translate exceptions emitted from base or member constructors, and all other function try blocks are rarely if ever useful at all.

Even if you don't want a particular constructor, you often have to define it, just for the benefit of descendant subclasses who may need it as a base for their constructors.
Constructors logically return an object, yet you are not allowed to declare that fact.
This is also a good place to move constructor code that is failing because it uses methods overridden my subclasses that reference fields not yet initialised by the subclass's constructor which has not yet run yet.

 Static Constructor in C# and their usages   (Site not responding. Last check: 2007-10-12)
Static constructor is used to initialize static data members as soon as the class is referenced
A static constructor does not take access modifiers or have parameters and can't access any non-static data member of a class.
Since static constructor is a class constructor, they are guaranteed to be called as soon as we refer to that class or by creating an instance of that class.

This constructor string is commonly used to specify an initialization string that must be accessible to all object instances of the component.
The constructor string is commonly used to specify a Database connection string that the object instances of a component use to establish database connections.
An advantage of using the constructor string for this purpose is that it prevents the connection string from being hardcoded in the component's code.

 Pasing Arguements Into A Constructor - GameDev.Net Discussion Forums
The default constructor is called when, as I mentioned before, you don't specify any arguments with your variable definition.
First, the copy constructor, which takes a const reference to an object of the same class, is called whenever you pass a parameter by value, or return a result in the same way - though compilers may optimize that away in some cases.
Now for basic types it may not seem significant, but if you have member object which have constructors of their own, those constructors may indeed be costly, and there is little point in default-constructing an object if you're going to overwrite it immediately.

 Code Generation Network - Constructor()
Constructor can be used to generate MS SQL and MS Access databases and assists in creating 3-tier database applications.
Constructor() can be used to build prototypes or even full windows or web applications from a UML class definition – which itself can be easily created using the builtin model editor and class diagram tool, or by reverse-engineering a database schema.
Constructor allows the developer to iterate changes to the model, add custom business logic, adjust the mappings between class, code, data and UI models, and centralize user actions for both Win and Web forms through an ‘abstract’ component layer.

 Constructor function at opensource encyclopedia   (Site not responding. Last check: 2007-10-12)
A constructor function, in computer programming, is a member function of a class and always has the same name as the class.
It is used to create an object instance of a particular class and possibly also populate some or all of that object instance's attributes.
A class may have more than one constructor function allowing multiple ways to create an object instance, as in example 2 below, an instance of an account can be created without supplying an initial balance and one where an initial balance can be supplied in the call to the constructor function.

 Opinion: Why I prefer constructor-based dependency injection
Constructor based intialisation should still be used when the order of initialisation matters but for simpel objects this does not apply.
I used to prefer constructor based initialisation but the problem comes when your object grows to need a new property.If you provide a sensible default then your contract with the original code is unchanged.Otherwise you must update the constructor and also update every piece of code that uses the object.
Also constructor dependency injection and 'configure method injection' clearly separates configuration state from other component state that may or may not be transient.

The Constructor had an arm, which it could move about; and a tip, which could be used to change the state of the cell on which it rested.
While this solution demonstrates the theoretical validity of the idea, von Neumann's kinematic constructor (which was not worked out in such detail) has had perhaps a greater influence, for it is a model of self replication which can more easily be adapted to the three-dimensional world in which we live.
The kinematic constructor was a robotic arm which moved in three-space, and which grasped parts from a sea of parts around it.
