java 获取list最后一个元素(对象)

import java.util.Arrays;
import java.util.List;
 
 
public class Test {
    public static void main(String[] args) {
        List list = Arrays.asList("node", "java", "c++", "react", "javascript");
        Object result = list.get(list.size() - 1);
        System.out.println(result);
        Object result2 = list.stream().skip(list.size() - 1).findFirst().orElse("no last element");
        System.out.println(result2);
        Object result3 = list.stream().reduce((first, second) -> second).orElse("no last element");
 
        System.out.println(result3);
    }
    // 同样也可以适用于list<Object>的取值
