Google Guava“zip”两个清单 [英] Google Guava "zip" two lists

问题描述

使用Google Guava（Google Commons），有没有办法将两个大小相同的列表合并到一个列表中，新列表包含两个输入列表的复合对象？

Using Google Guava (Google Commons), is there a way to merge two equally sized lists into one list, with the new list containing composite objects of the two input lists?

示例：

public class Person {
    public final String name;
    public final int age;

    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }

    public String toString() {
        return "(" + name + ", " + age + ")";
    }
}

和

List<String> names = Lists.newArrayList("Alice", "Bob", "Charles");
List<Integer> ages = Lists.newArrayList(42, 27, 31);

List<Person> persons =
    transform with a function that converts (String, Integer) to Person
System.out.println(persons);

输出：

[(Alice, 42), (Bob, 27), (Charles, 31)]

推荐答案

看起来这个目前不在Guava中，但是是一个理想的功能。请参阅此github问题，特别是 Iterators.zip（）。

Looks like this is not currently in Guava, but is a desired feature. See this github issue, in particular Iterators.zip().
