The Supplier interface in Java 8 is a functional interface that represents a supplier of results. It is part of the java.util.function package and does not take any arguments but returns a result. This interface is often used for lazy generation of values or instances.
Key Points:
Functional Interface: It has a single abstract method, making it a functional interface suitable for lambda expressions and method references.
Method: The primary method is get(), which returns a result.
Usage: Commonly used for deferred execution or supplying values on demand.
