Stream Primes

This repository contains an own implementation of a Stream inspired by Functional Programming in Scala. It provides an implementation for

• constant: Create a infinite stream with given integer
• from: Create an infinite stream counting from the given integer
• from: Create a stream from given list
• empty: Empty stream
• filter: Filter a stream for elements which yield true for a given predicate
• foldRight: Reduce the stream to one value with given aggregate BiFunction and neutral element z.
• unfold: Unfold stream from initial state and a next state function.
• primes: Infinite stream of prime numbers
• rangeClosed: Range from start to end (inclusive)
• noneMatch: True if none of the elements in a stream fullfills the predicate
• anyMatch: True if at least one element in a stream fullfills the predicate
• allMatch: True if all elements in a stream fullfill the predicate
• limit: limits the amount of elements in the stream
• map: apply given function to each element of the stream

Primes generation can also be done with Java 8s Stream implementation (look into test source package).

Examples

// Following code constructs a stream of one element
Stream<String> one = Stream.cons(() -> "Just one", () -> Stream.empty());

// Filter stream
Stream<String> one = Stream.cons(() -> "one", () -> Stream.cons(() -> "second", () -> Stream.empty())).filter("one"::equals); // Stream with one element

// Constant stream of ones
Stream<Integer> ones = Stream.constant(1);
