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;
}
}
