IntStream generate() method in Java

IntStream generate(IntSupplier s) returns an infinite sequential unordered stream where each element is generated by the provided IntSupplier(a supplier of int-valued results). This is suitable for generating constant streams, streams of random elements, etc.

Syntax :

static IntStream generate(IntSupplier s)

Parameters :

1. IntStream : a sequence of primitive int-valued elements.
2. IntSupplier : a supplier of int-valued elements.
3. s : IntSupplier for generated elements.

Return Value : a new infinite sequential unordered IntStream.

Example 1 : To generate stream of random integer.

// Java code for IntStream.generate()
// to generate an infinite sequential
// unordered IntStream
import java.util.*;
import java.util.stream.IntStream;

class GFG {

    // Driver code
    public static void main(String[] args)
    {

        // using IntStream.generate() method
        // to generate 7 random Integer values
        IntStream stream = IntStream.generate(()
                          -> { return (int)(Math.random() * 10000); });

        // Displaying the randomly generated values
        stream.limit(7).forEach(System.out::println);
    }
}
