Given the task is to generate an infinite sequential unordered stream of integers in Java.

Using IntStream.iterate():
Using the IntStream.iterate() method, iterate the IntStream with i by incrementing the value with 1.
Print the IntStream with the help of forEach() method.
import java.util.stream.*;

public class P_AI {

// Main method
public static void main(String[] args)
{

IntStream

// Iterate the IntStream with i
// by incrementing the value with 1
.iterate(0, i -> i + 1)

// Print the IntStream
// using forEach() method.
.forEach(System.out::println);
}
}
Output:

0
1
2
3
4
5
.
.
.
Using Random.ints():
Get the next integer using ints() method
Print the IntStream with the help of forEach() method.
import java.util.stream.*;
import java.util.*;

public class P_AI {

// Main method
public static void main(String[] args)
{

// Create a Random object
Random random = new Random();

random

// Get the next integer
// using ints() method
.ints()

// Print the IntStream
// using forEach() method.
.forEach(System.out::println);
}
}
Output:

-1214876682
911266110
1224044471
-1867062635
1893822159
1226183018

Using IntStream.generate():
Generate the next integer using IntStream.generate() and Random.nextInt()
Print the IntStream with the help of forEach() method.
import java.util.stream.*;
import java.util.*;

public class P_AI {

// Main method
public static void main(String[] args)
{

// Create a Random object
Random random = new Random();

IntStream

// Generate the next integer
// using IntStream.generate()
// and Random.nextInt()
.generate(random::nextInt)

// Print the IntStream
// using forEach() method.
.forEach(System.out::println);
}
}
Output:

-798555363
-531857014
1861939261
273120213
-739170342
