The constructor generation wizard creates a non-default constructor that takes parameters for selected fields, properties and auto-properties.
- ShortCut for adding class field to existing constructor in AndroidStudio or IDEA. Ask Question Asked 4 years. But this way you can create new constructor, but cant modify existing. – mohax Jan 9 '16 at 12:31. IntelliJ shortcut to show a popup of methods in a class that can be searched.
- Adds an option to generate a copy constructor to the generate menu (alt + ins).
Select one of the options to change visibility scope of the constructor. Use these buttons to add/remove exceptions. For each new exception, specify its type. Note that code completion works here. As you type, the suggestion list shrinks to show the matching options. 11 rows Select one of the options to change visibility scope of the constructor.

In the editor, set the caret at the type name or within a type at the line where you want to insert a constructor. If the caret is on the type name, the generated code will be added in the beginning of the type declaration. Press Alt+Insert or choose from the main menu.
Shortcuts In Intellij
All generated constructors follow the same pattern where:
Each field, property, or auto-property included in the constructor is initialized with a parameter.
The name of the parameter is derived from the name of the corresponding field or property.
You can quickly generate constructors by typing ctor (without parameters), ctorf (with parameters that initialize all fields) or ctorp (with parameters that initialize all properties).
If there are non-default base type constructors, the required parameters are added to the generated constructor and passed to the base class constructor.
In the example below, this command is used to generate a new Circle constructor that takes two additional parameters to initialize _radius and _center fields.
Before generation | After generation |
|---|---|
internal class Shape{ public Shape(Color color) { Color = color; } public Color Color { get; }}class Circle : Shape{ int _radius; Point _center; public Circle(Color color) : base(color) { }} | internal class Shape{ public Shape(Color color) { Color = color; } public Color Color { get; }}class Circle : Shape{ int _radius; Point _center; public Circle(Color color) : base(color) { } public Circle(Color color, int radius, Point center) : base(color) { _radius = radius; _center = center; }} |
You can configure common code generation preferences on the Editor | Members Generation page of JetBrains Rider settings Ctrl+Alt+S.

To generate a constructor
In the editor, set the caret at the type name or within a type at the line where you want to insert a constructor. If the caret is on the type name, the generated code will be added in the beginning of the type declaration.
Press Alt+Insert or choose Code | Generate... from the main menu. Alternatively, you can press Ctrl+Shift+A, start typing the command name in the popup, and then choose it there.
In the Generate popup, select Constructor.
- In the Generate dialog that appears, select type members that should be initialized in the new constructor. Optionally, select one or several base class constructors. For every selected base constructor, a new constructor will be generated that will call the base and additionally initialize selected members.
Optionally, use the following controls in the dialog:
Access Rights — allows you to define access rights for the generated constructor.
Check parameters for null (appears if the class has fields or properties of nullable types) — if this checkbox is selected, JetBrains Rider will generate configurable null checks for each nullable parameter, for example:
if (param null) throw new ArgumentNullException(nameof(param));Make parameters optional — if this checkbox is selected, JetBrains Rider will make all parameters of the generated constructor optional and add default values corresponding to the parameter types.
Click OK to complete the wizard.
