StreamMaxMinDemo
import java.util.Arrays;
import java.util.Comparator;
import java.util.List;

public class StreamMaxMinDemo
{
    public static void main(String[] args)
    {
        List<String> list = Arrays.asList("Z", "B", "I", "E");

        /*
         * max(): It finds maximum element for the given Comparator.
         */
        String max = list.stream()
                         .max(Comparator.comparing(String::valueOf)).get();
        
        System.out.println("Max:" + max);

        /*
         * min(): It finds minimum element for the given Comparator.
         */
        String min = list.stream()
                         .min(Comparator.comparing(String::valueOf)).get();
        
        System.out.println("Min:" + min);
    }
}
Output
Max:Z
Min:B
