Unnecessary 'this' qualifier

Reports unnecessary this qualifier.

Using this to disambiguate a code reference is discouraged by many coding styles and may easily become unnecessary via automatic refactorings.

Example:

  class Foo {
    int x;
    void foo() {
      this.x = 2;
    }
  }

After the quick-fix is applied:

  class Foo {
    int x;
    void foo() {
      x = 2;
    }
  }

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.

UnnecessaryThis

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 assignments to fields. For instance, this.x = 2; won't be reported, but int y = this.x; will be.

Here you can find the description of settings available for the Unnecessary 'this' qualifier inspection, and the reference of their default values.
