问题描述

我想使用数组创建对象名称.我该怎么做?

I want to create object name using arrays. How can I do it?

例如:

String dizi ={"person1","person2","person3"};
Person dizi[0] = new Person();

推荐答案

您不能将数组中存储的对象类型从 String 更改为 Person.相反，您将需要两个单独的数组，并且假设您有一个 Person(String) 构造函数，循环遍历第一个数组以填充第二个数组:

You cannot change the type of object stored in the array from String to Person. Instead, you will need two separate arrays, and supposing you have a Person(String) constructor, loop over first array to fill second array:

String[] names = {"person1","person2","person3"};
Person[] persons = new Person[3];
for (int i = 0; i < 3; i++)
    persons[i] = new Person(names[i]);
