Package-visible nested class

Last modified: 03 December 2024

Reports nested classes that are declared without any access modifier (also known as package-private).

Example:

public class Outer {
  static class Nested {}  // warning
  class Inner {}          // warning
  enum Mode {}            // warning depends on the setting
  interface I {}          // warning depends on the setting
}
