用Java动态创建哈希映射 [英] Dynamic Creation of Hash Maps in Java

问题描述

I am doing an application which needs dynamic creation of Hash Maps.

Map<K,V> parent=new Hash Map<K,V>();

      if(Some Condition)
      {
        //Parent map will be added with another sub map

        parent = Map<K,Map<K,V>>();

        //    and So on
       }

I need only 3 levels Like this

parent = Map<K,Map<K,Map<K,V>>>();

推荐答案

您究竟想要获得什么？

这是一个3维HashMap。应该在哪里需要？



您需要非常小心键和值 - 不要混淆它们。



但我认为必须有一个更简单的解决方案。

创建一个包含HashMap为2和3的Object怎么样？Dimension？

至少可以减少混淆。

What exactly do you want to acchive?
This is a 3 dimensional HashMap. Where should that be needed?

You need to be very careful with the Keys and the values - do not mix them up.

But I think there must be a simpler solution.
How about creating an Object that holds the HashMap of 2. and 3. Dimension?
Could be at least less confusing.
