To insert element into the stream, you need to use the add() method of the IntStream.Builder.The syntax is as follows:default IntStream.Builder add(int t)Here, parameter t is the element to be inserted.Declare IntStream.Builder:IntStream.Builder builder = IntStream.builder();Add some elements to the Builder using add() method:builder.add(10); builder.add(25); builder.add(33); builder.add(42);The following is an example to implement IntStream.Builder add() method in JavaExample Live Demoimport java.util.stream.IntStream; public class Demo {    public static void main(String[] args) {       IntStream.Builder builder = IntStream.builder();       System.out.println("Elements in the stream...");       builder.add(10);       builder.add(25);       builder.add(33);       builder.add(42); ...

Insert an element into IntStream using the IntStream.Builder accept() method. It adds element to the stream being built.The syntax is as follows:void accept(int t)Here, parameter t is the input argument.The elements are inserted as shown below in the stream:builder.accept(10); builder.accept(15); builder.accept(25); builder.accept(39); builder.accept(45);The following is an example to implement IntStream.Builder accept() method in Java:Example Live Demoimport java.util.stream.IntStream; public class Demo {    public static void main(String[] args) {       IntStream.Builder builder = IntStream.builder();       System.out.println("Elements of the stream...");       builder.accept(10);       builder.accept(15);       builder.accept(25);       builder.accept(39);       ...

A British mathematician in an around 1970 created his “Game of Life” – which are basically a set of rules depicting the chaotic yet patterned growth of a colony of biological organisms. The “Game of Life” is a two-dimensional grid consists of “living” and “dead” cells.Rules of Game of lifeOverpopulation: A cell dies(off) if its surrounded by more than three living cells.Static: A cell lives(on) if its surrounded by two or three living cells.Underpopulation: A cell dies(off) if its surrounded by fewer than two living cells.Reproduction: A cell becomes live(on) if a dead cell is surrounded by exactly three cells. Cell ...

To convert Primitive Array to Stream, you need to use the of() method.Let’s say the following is our Primitive Array:int[] myArr = new int[] { 20, 50, 70, 90, 100, 120, 150 };Now, use the of() method to convert the primitive array to stream:IntStream stream = IntStream.of(myArr);The following is an example to convert primitive array to stream in Java:Example Live Demoimport java.util.stream.IntStream; import java.util.*; public class Main {    public static void main(String[] args) {       int[] myArr = new int[] { 20, 50, 70, 90, 100, 120, 150 };       System.out.println("The Primitive Array = "+Arrays.toString(myArr));   ...

NodeJs and Python are two main preferred languages among developers and web designers. But there are couple of areas where NodeJs fall short of python are numerical and scientic computation (AI, Machine learning, deep learning etc.). Whereas python provides lots of libraries to work with scientific computing lot easier.Luckly, we can utilise the python libraries within our nodejs application by running python in the background and return back the result.For this we are going to use the child_process standard library of NodeJs to spawn a pyton process in the background, do computation and return back the result to our node ...

In this we are going to use PyTorch to train a CNN to recognize handwritten digit classifier using the MNIST dataset.MNIST is a widely used dataset for hand-written classification task covering more than 70k labeled 28*28 pixel grayscale images of handwritten digits. The dataset contains almost 60k training images and 10k test images. Our job is to train a model using 60k training images and subsequently test its classification accuracy on 10k test images.InstallationFirst we need the MXNet latest version, for that just run the following on your terminal:$pip install mxnetAnd you will something like, Collecting mxnet Downloading https://files.pythonhosted.org/packages/60/6f/071f9ef51467f9f6cd35d1ad87156a29314033bbf78ad862a338b9eaf2e6/mxnet-1.2.0-py2.py3-none-win32.whl (12.8MB) ...

If you have a string and you want to convert it into IntStream with ASCII values, then it can be easily achieved using the below code.To work with IntStream class, you need to import the following package:import java.util.stream.IntStream;Let’s say the following is our string:String str = "Benz";Convert the above string to IntStream:IntStream stream = str.chars();The following is an example to convert String to IntStream in Java:Example Live Demoimport java.util.stream.IntStream; public class Demo {    public static void main(String[] args) {       String str = "Benz";       System.out.println("String to be converted = " + str);       ...

Let’s say the following is our character array:Character arr[] = { 'V', 'e', 'h', 'i', 'c', 'l' , 'e' };To convert the above character array to IntStreamIntStream stream = Stream.of(arr).flatMapToInt(IntStream::of);We have used the flatMapToInt() method for this.The following is an example to convert character array to IntStream in Java:Example Live Demoimport java.util.stream.*; public class Main {    public static void main(String[] args) {       Character arr[] = { 'V', 'e', 'h', 'i', 'c', 'l' , 'e' };       System.out.println("The character array = ");       for (char value : arr) {          System.out.println("Value ...

The build() method of the LongStream.Builder class builds the stream and returns the built stream. The following is the syntax:LongStream build()Import the following package for the LongStream.Builder class in Java:import java.util.stream.LongStream;Declare a LongStream.Builder and add elements:LongStream.Builder builder = LongStream.builder(); builder.add(24000L); builder.add(47470L); builder.add(12999L);Now, use the build() method to build the stream:builder.build()The following is an example displaying how to implement build() method of LongStream.Builder in Java:Example Live Demoimport java.util.stream.LongStream; public class Demo {    public static void main(String[] args) {       LongStream.Builder builder = LongStream.builder();       builder.add(24000L);       builder.add(47470L);       builder.add(12999L);       ...
