How can I construct a registry?

[haykam821]

How can a registry that can be registered to using code (rather than JSON) be constructed?

They should act like existing vanilla registries, like the block and item registries.

private static final Identifier REGISTRY_ID = new Identifier("modid", "example");
private static final RegistryKey<Registry<T>> REGISTRY_KEY = RegistryKey.ofRegistry(REGISTRY_ID);
public static final Registry<T> REGISTRY = new SimpleRegistry<>(REGISTRY_KEY, Lifecycle.stable());
