The generate() method of the DoubleStream class returns an infinite sequential unordered stream where each element is generated by the provided DoubleSupplier.The syntax is as followsstatic DoubleStream generate(DoubleSupplier s)Here, the parameter s is the DoubleSupplier for generated elements. The DoubleSupplier is a supplier of double-valued results. To use the DoubleStream class in Java, import the following packageimport java.util.stream.DoubleStream;The following is an example to implement DoubleStream generate() method in JavaExample Live Demoimport java.util.*; import java.util.stream.DoubleStream; public class Demo {    public static void main(String[] args) {       DoubleStream doubleStream = DoubleStream.generate(()       -> { return (double)(Math.random() * 100); ...

The limit() method of the IntStream class is used to return a stream consisting of the elements of this stream, truncated to be no longer than maxSize in length. Here, maxSize is the parameter.The syntax is as followsIntStream limit(long maxSize)Here, the maxSize parameter is the count of elements the stream is limited to.At first, an IntStream is created with the range() method to set a sequential order of elementsIntStream intStream = IntStream.range(20, 40);Now, use the limit() method, whose parameter is the maxSize i.e. the count of elements the stream is limited tointStream.limit(8)The following is an example to implement IntStream limit() ...
