## Uses of Interface
java.util.function.IntFunction

Packages that use IntFunction
java.util: Contains the collections framework, legacy collection classes, event model, date and time facilities, internationalization, and miscellaneous utility classes (a string tokenizer, a random-number generator, and a bit array).
java.util.stream: Classes to support functional-style operations on streams of elements, such as map-reduce transformations on collections.

### Uses of IntFunction in java.util

Methods in java.util with parameters of type IntFunction
`static <T> void` Arrays.`parallelSetAll(T[] array, IntFunction<? extends T> generator)` Set all elements of the specified array, in parallel, using the provided generator function to compute each element.
`static <T> void` Arrays.`setAll(T[] array, IntFunction<? extends T> generator)` Set all elements of the specified array, using the provided generator function to compute each element.

### Uses of IntFunction in java.util.stream

Methods in java.util.stream with parameters of type IntFunction
`IntStream` IntStream.`flatMap(IntFunction<? extends IntStream> mapper)` Returns a stream consisting of the results of replacing each element of this stream with the contents of a mapped stream produced by applying the provided mapping function to each element.
`<U> Stream<U>` IntStream.`mapToObj(IntFunction<? extends U> mapper)` Returns an object-valued `Stream` consisting of the results of applying the given function to the elements of this stream.
`<A> A[]` Stream.`toArray(IntFunction<A[]> generator)` Returns an array containing the elements of this stream, using the provided `generator` function to allocate the returned array, as well as any additional arrays that might be required for a partitioned execution or for resizing.
