PackageVisibleInnerClass

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
  }

Configure the inspection:

• Use the Ignore package-visible inner enums option to ignore package-private inner enums.
• Use the Ignore package-visible inner interfaces option to ignore package-private inner interfaces.
