Remarks

Load the first available service provider of this loader's service. This convenience method is equivalent to invoking the #iterator() iterator() method and obtaining the first element. It therefore returns the first element from the provider cache if possible, it otherwise attempts to load and instantiate the first provider.

The following example loads the first available service provider. If no service providers are located then it uses a default implementation.

{@code
               CodecFactory factory = ServiceLoader.load(CodecFactory.class)
                                                   .findFirst()
                                                   .orElse(DEFAULT_CODECSET_FACTORY);
            }
