Java 8 Streams - LongStream.findAny Examples

Java 8 Streams Java Java API

Interface:

java.util.stream.LongStream

Method:

OptionalLong findAny()

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

This is a terminal-short-circuiting operation.

Examples

package com.logicbig.example.longstream;

import java.util.stream.LongStream;

public class FindAnyExample {

    public static void main(String... args) {
        LongStream longStream = LongStream.of(1, 2, 3, 2, 5, 4);
        long l = longStream.findAny()
                           .orElse(-1);
        System.out.println(l);
    }
}

Output

Parallel stream:

package com.logicbig.example.longstream;

import java.util.stream.LongStream;

public class FindAnyExample2 {

    public static void main(String... args) {
        LongStream longStream = LongStream.of(1, 2, 3, 2, 5, 4);
        long l = longStream.parallel()
                           .findAny()
                           .orElse(-1);
        System.out.println(l);
    }
}
