Object Construction and Destruction
| construction | destruction | |
|---|---|---|
| ABAP Objects | data variable type ref to class . create object variable «exporting parameter = argument». |
|
| C++ (STL) | class variable«(parameters)»; or class *variable = new class«(parameters)»; |
delete pointer; |
| C# | class variable = new class(parameters); | variable.Dispose; |
| Java | variable.dispose; | |
| D | delete variable; | |
| Objective-C (Cocoa) | class *variable = init]; or class *variable = initWithFoo:parameter «bar:parameter ...»]; |
; |
| Python | variable = class(parameters) | del variable (Normally not needed) |
| Visual Basic .NET | Dim variable As New class(parameters) | variable.Dispose |
| Eiffel | create variable or create «{TYPE}» variable.make_foo «(parameters)» or variable := create {TYPE} or variable := create {TYPE}.make_foo «(parameters)» |
|
| PHP | $variable = new class(parameters); | unset($variable); |
| Perl 5 | «my »$variable = class->new«(parameters)»; | undef($variable); |
| Perl 6 | «my »$variable = class.new«(parameters)»; | $variable.undefine; |
| Ruby | variable = class.new«(parameters)» | |
| Windows PowerShell | $variable = New-Object «-TypeName» class ««-ArgumentList» parameters» | Remove-Variable «-Name» variable |
| OCaml | let variable = new class «parameters» or let variable = object members end |
|
| F# | let variable = «new »class(«parameters») | |
| Smalltalk | "The class is an Object. Just send a message to a class, usually #new or #new:, and many others, for example:" Pointy x: 10 y: 20. Array with: -1 with: 3 with: 2. |
|
| JavaScript | var variable = new class«(parameters)» or var variable = { «key1: value1«, key2: value2 ...»»} |
|
| Object Pascal / Delphi | ClassVar := ClassType.ConstructorName(parameters); | ClassVar.Free; |

Famous quotes containing the words object, construction and/or destruction:
“A signal is comprehended if it serves to make us notice the object or situation it bespeaks. A symbol is understood when we conceive the idea it presents.”
—Susanne K. Langer (1895–1995)
“There’s no art
To find the mind’s construction in the face.”
—William Shakespeare (1564–1616)
“We are heading towards catastrophe. I think the world is going to pieces. I am very pessimistic. Why? Because the world hasn’t been punished yet, and the only punishment that could be adequate is the nuclear destruction of the world.”
—Elie Wiesel (b. 1928)
