如何在Java中初始化有序的(int，string)对 [英] How to initialize an ordered pair of (int,string) in java

问题描述

只想问一下如何初始化Java中具有(int，string)值的有序对.

Just want to ask how to initialize an ordered pair having the value of (int,string) in java.

示例为:

(1，迈克尔)(2，约瑟夫)(3，阿尔伯特)(4，玛丽亚)

(1 , Michael) (2, Joseph) (3, Albert) (4, Maria)

**添加了问题，如果名称或字符串来自数组怎么办?

** Added question, what if the names or the string came from an array??

推荐答案

您可以使用具有整数和字符串字段的自定义类:

You can have a custom class having integer and string fields:

class Pair
{
  int num;
  String name;

  Pair(int num, String name)
  {
     this.num = num;
     this.name = name;
  }
}

然后，您可以拥有这些 Pair 对象的数组:

Then, you can have an array of these Pair objects:

Pair[] pairs = new Pair[10];

初始化可能是这样的:

String[] strings; // your string array.

for(int i=0; i<10; i++)
   Pair[i] = new Pair(i, strings[i]);
