Java，在多维数组中存储混合数据类型的最简单方法? [英] Java, easiest way to store mixed-data types in a multidimensional array?

问题描述

我有一个包含一些String和int的文件，我希望将它们存储在2D'array'中.最好的方法是什么?我有一段时间没有做Java了，我一直在使用VBA(那里没有数据类型)，所以我有点生锈.

Ive got a file with some String and ints I wish to store in a 2D 'array'. What is the best way of doing this? I havent done Java for a while and i've been using VBA (where you have no datatypes), so i'm a little bit rusty.

推荐答案

如果需要的话，将其制成二维对象数组.

Make it a two dimensional array of Objects, if you must.

一个更好的解决方案是找到一个通用接口，并使其成为该接口的二维数组.

A better solution is to find a common interface, and make it a two dimensional array of that interface.

最好的解决方案是做类似的事情

The best solution is to do something like

public class Entry {

  private String name;

  private int value;

  public Entry(String name, int value) {
    this.name = name;
    this.value = value;
  }

  public String getName() {
    return this.name;
  }

  public int getValue() {
    return this.value;
  }

}

并使其成为 Entry s的一维数组.请注意，如果您真的想追求成功"，请将上述 Entry 类重命名为实际上有意义的类名称.

And make it a single dimensional array of Entrys. Note that if you really wanted to "go for the gold" rename the above Entry class to a class name that actually makes sense.
