Java 8 Streams Java Java API

Interface:

java.util.stream.IntStream

Method:

OptionalInt findAny()

Returns an Optional describing an element of the stream, or an empty Optional if the stream is empty.

This is a terminal-short-circuiting operation.

Examples

package com.logicbig.example.intstream;

import java.util.stream.IntStream;

public class FindAnyExample {

    public static void main(String... args) {
        IntStream intStream = IntStream.of(1, 2, 3, 2, 5, 4);
        int i = intStream.findAny()
                         .orElse(-1);
        System.out.println(i);
    }
}

Output

Using findAny() method in parallel stream.

package com.logicbig.example.intstream;

import java.util.stream.IntStream;

public class FindAnyExample2 {

    public static void main(String... args) {
        IntStream intStream2 = IntStream.of(1, 2, 3, 2, 5, 4);
        int i2 = intStream2.parallel()
                           .findAny()
                           .orElse(-1);
        System.out.println(i2);
    }
}
