Implicit call to 'super()'

Reports constructors that do not begin with a call to "super" constructor or another constructor of the same class.

Such constructors can be thought of as implicitly beginning with a call to super(). Some coding standards prefer that such calls to super() be made explicitly.

Example:

  class Foo {
    Foo() {}
  }

After the quick-fix is applied:

  class Foo {
    Foo() {
      super();
    }
  }

Locating this inspection

By ID

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

ImplicitCallToSuper

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

Settings or Preferences | Editor | Inspections | Java | Code style issues

Use the inspection settings to ignore classes extending directly from Object. For instance:

  class Foo {
    Foo() {} // Not reported
  }

  class Bar extends Foo {
    Bar() {} // Implicit call to 'super()'
  }

Inspection options

Here you can find the description of settings available for the Implicit call to 'super()' inspection, and the reference of their default values.

Ignore for direct subclasses of 'java.lang.Object': Default value:
Not selected

Suppressing Inspection

You can suppress this inspection by placing the following comment marker before the code fragment where you no longer want messages from this inspection to appear:

//noinspection ImplicitCallToSuper
