是否可以在Java中动态生成变量名称？ [英] Is there away to generate Variables' names dynamically in Java?

问题描述

假设我需要生成变量以保存用户的一些输入（我不知道它们有多少）。不使用 Array ， ArrayList （以及其他类型的列表和地图）我的代码可以生成（假设） String 变量X次，名称如（ String var001 ， String var002 ，字符串var003 等）？如果是，请提供示例代码。

Let's say that I need to generate variables to hold some input from the user (I don't know how many they are). Without using Array, ArrayList (and other kind of lists and maps) can my code generate (lets say) String variables X times with names like (String var001, String var002, String var003, etc)? If yes, please provide sample code.

推荐答案

以下是我实施并帮助我轻松修复解决方案的方式很多障碍。

Following is the way that i have implemented and helped me to fix my solution easily without much hurdles.

//创建数组列表

List accountList = new ArrayList(); 




for(int k=0;k < counter;k++){
        accountList.add(k, (String)flowCtx.getValueAt("transitId"+m));
}

迭代循环并将对象添加到带索引的arraylist中。

Iterating the loop and adding the objects into the arraylist with the index.

//在索引的帮助下在运行时检索对象

//Retrieving the object at run time with the help of the index

String a = accountList.get(i));
