You can also generate Infinite Stream of Integers in Java with IntStream.generate() method. Here, we have used the Random class to get the list of random integers:Random r = new Random();After that use IntStream.generate() and the nextInt() method gets the next random integer:IntStream.generate(r::nextInt)The following is an example displaying how to generate Infinite Stream of Integers with IntStream.generate() in Java:import java.util.stream.*; import java.util.*; public class Main { public static void main(String[] args) { Random r = new Random(); IntStream.generate(r::nextInt).forEach(System.out::println); } }Here is the output:565757777 3535363636 9879879879 -686549988Read More

The builder() method in IntStream class is used to return a builder for an IntStream.The syntax is as follows:static IntStream.Builder builder()Here, we have created an IntStream and used the builder() method. An element is added using add() method:IntStream intStream = IntStream.builder().add(25).build();The following is an example to implement IntStream builder() method in Java −Example Live Demoimport java.util.*; import java.util.stream.Stream; import java.util.stream.IntStream; public class Demo { public static void main(String[] args) { IntStream intStream = IntStream.builder().add(25).build(); intStream.forEach(System.out::println); } }output25

The generate() method of the LongStream class returns an infinite sequential unordered stream where each element is generated by the provided LongSupplier.The syntax is as follows:static LongStream generate(LongSupplier s)Here, s is the LongSupplier for generate elements. The LongSupplier is the supplier of long-valued results.To use the LongStream class in Java, import the following package:import java.util.stream.LongStream;The following is an example to implement LongStream generate() method in Java −Example Live Demoimport java.util.stream.LongStream; public class Demo { public static void main(String[] args){ LongStream longStream = LongStream.generate(() -> { return (long)(Math.random() * 100); }); ...

The parallel() method of the IntStream class in Java returns an equivalent parallel stream. The method may return itself, either because the stream was already parallel, or because the underlying stream state was modified to be parallel.The syntax is as follows:IntStream parallel()Create an IntStream and you can use the range() method as well to set the range of elements:IntStream intStream = IntStream.range(20, 35);Now, use the parallel() method:intStream.parallel()The following is an example to implement IntStream parallel() method in JavaExample Live Demoimport java.util.stream.IntStream; public class Demo { public static void main(String[] args) { IntStream intStream = IntStream.range(20, 35); ...
