* <T,R>`: Takes an object of type T and returns R.
* `**Supplier:**
* $<T>$`: Returns an object of type T.
* `**Predicate:**
* $<T>$`: Returns a boolean value based on input of type T.
* `**Consumer:**
* $<T>$`: Performs an action with a given object of type T.
* **BiFunction:** Like Function but with two parameters.
* **BiConsumer:** Like Consumer but with two parameters.
