Singleton

Reports singleton classes.

Singleton classes are declared in a way that only one instance of the class can ever be instantiated. Singleton classes complicate testing, and their presence may indicate a lack of object-oriented design.

Example:

class Singleton {
  private static final Singleton ourInstance = new Singleton();

  private Singleton() {
  }

  public Singleton getInstance() {
      return ourInstance;
  }
}
