As we know Consumer<T> functional interface is used in forEach() so similarly does Java has a use case for Supplier other than the custom ones?

  • Here is every use of `java.util.function.Supplier` in the standard library for Java 19: https://docs.oracle.com/en/java/javase/19/docs/api/java.base/java/util/function/class-use/Supplier.html – Slaw Feb 06 '23 at 02:11
  • And for fun, here's the same for `java.util.function.Consumer`: https://docs.oracle.com/en/java/javase/19/docs/api/java.base/java/util/function/class-use/Consumer.html – Slaw Feb 06 '23 at 02:12

java.util.Optional.orElseGet(Supplier<T> supplier) can be used to provide a default value for an Optional if it is empty.

java.util.stream.Stream.generate(Supplier<T> s) can be used to generate a stream of values.
