在Java 8中，我们可以使用reduce或skip获取Stream的最后一个元素。
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 list = Arrays.asList("node", "java", "c++", "react", "javascript");
String result = list.stream().reduce((first, second) -> second).orElse("no last element");
System.out.println(result);
}
输出量
javascript

2. Stream.skip
Java8Example2.java
package com.mkyong;
import java.util.Arrays;
import java.util.List;
public class Java8Example2 {
public static void main(String[] args) {
List list = Arrays.asList("node", "java", "c++", "react", "javascript");
// get last element from a list
String result = list.get(list.size() - 1);
System.out.println(result);
// get last element from a stream, via skip
String result2 = list.stream().skip(list.size() - 1).findFirst().orElse("no last element");
System.out.println(result2);
}
