Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface Supplier<T>

A functional interface (callback) that provides a single value or throws an exception.

This interface was added to allow throwing any subclass of Throwables, which is not directly possible with the Java standard Callable interface.

Since:

3.0.0
