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:
“For, if a “good speaker,” never so eloquent, does not see into the fact, and is not speaking the truth of that ... is there a more horrid kind of object in creation?”
—Thomas Carlyle (1795–1881)
“No construction stiff working overtime takes more stress and straining than we did just to stay high.”
—Gus Van Sant, U.S. screenwriter and director, and Dan Yost. Bob Hughes (Matt Dillon)
“He will deliver you from six troubles; in seven no harm shall touch you. In famine he will redeem you from death, and in war from the power of the sword. You shall be hidden from the scourge of the tongue, and shall not fear destruction when it comes. At destruction and famine you shall laugh, and shall not fear the wild animals of the earth. For you shall be in league with the stones of the field, and the wild animals shall be at peace with you.”
—Bible: Hebrew, Job 5:19-23.
