LongStream max() method in Java

The max() method of the LongStream class in Java returns an OptionalLong describing the maximum element of this stream, or an empty optional if this stream is empty.

The syntax is as follows

OptionalLong max()

Here, OptionalLong is a container object which may or may not contain a long value.

To use the LongStream class in Java, import the following package

import java.util.stream.LongStream;

The following is an example to implement LongStream max() method in Java. The isPresent() method of the OptionalLong class returns true if the value is present

Example

 Live Demo

import java.util.*;
import java.util.stream.LongStream;
public class Demo {
   public static void main(String[] args) {
      LongStream longStream = LongStream.of(20000L, 15000L, 11000L, 74000L, 50000L);
      // Get the maximum element
      OptionalLong res = longStream.max();
      System.out.println("Maximum element...");
      if (res.isPresent()) {
         System.out.println(res.getAsLong());
      } else {
         System.out.println("Nothing!");
      }
   }
}

Output
