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:
“Organize first for knowledge, first with the object of making us know ourselves as a nation, for we have to do that before we can be of value to other nations of the world and then organize to accomplish the things that you decide to want. And ... don’t make decisions with the interest of youth alone before you. Make your decisions because they are good for the nation as a whole.”
—Eleanor Roosevelt (1884–1962)
“There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.”
—John Dewey (1859–1952)
“All my humor is based upon destruction and despair. If the whole world were tranquil, without disease and violence, I’d be standing on the breadline right in back of J. Edgar Hoover.”
—Lenny Bruce (1925–1966)
