In Java 8, we can use reduce or skip to get the last element of a Stream. 1. Stream.reduce Java8Example1.java package com.mkyong; import java.util.Arrays; import java.util.List; public class Java8Example1 { public static void main(String[] args) { List<String> list = Arrays.asList("node", "java", "c++", "react", "javascript"); String result = list.stream().reduce((first, second) -> second).orElse("no last element"); System.out.println(result); } …
In Java 8, we can use the Stream.reduce() to sum a list of BigDecimal. 1. Stream.reduce() Java example to sum a list of BigDecimal values, using a normal for loop and a stream.reduce(). JavaBigDecimal.java package com.mkyong; import java.math.BigDecimal; import java.util.LinkedList; import java.util.List; public class JavaBigDecimal { public static void main(String[] args) { List<BigDecimal> invoices = …
In Java 8, the Stream.reduce() combine elements of a stream and produces a single value. A simple sum operation using a for loop. int[] numbers = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; int sum = 0; for (int i : numbers) { sum += i; } System.out.println("sum : " + sum); …
