```
Class<? extends S> type()
```
    Returns the provider type. There is no guarantee that this type is accessible or that it has a public no-args constructor. The get() method should be used to obtain the provider instance.
    When a module declares that the provider class is created by a provider factory then this method returns the return type of its public static "provider()" method.
    
    Returns:
    
    The provider type
  - get
```
S get()

    get in interface Supplier<S>
    
    Returns:
    
    An instance of the provider.
    
    Throws:
    
    ServiceConfigurationError - If the service provider cannot be instantiated, or in the case of a provider factory, the public static "provider()" method returns null or throws an error or exception. The ServiceConfigurationError will carry an appropriate cause where possible.
