Java 嵌套树映射-值存储在单个键中

这是我第一次尝试实现树映射。在这种情况下，通过迭代检索到以下数据：

A
    a
    shape:square
    fill:yes
    size:very large
B
    b
        shape:square
        fill:yes
        size:very large
C
    c
        shape:square
        fill:yes
        size:very large

我需要将这些数据存储在树形图中。例如TreeMap（a，TreeMap（a，TreeMap（keySize，sizeAttribute）））

我实施了以下措施：

Map<String, TreeMap<String, TreeMap<String, String>>> squareRPM = new HashMap<String, TreeMap<String, TreeMap<String, String>>>(); //Everytime it changes object create a new squareRPM
            TreeMap<String, TreeMap<String, String>> component = new TreeMap<String, TreeMap<String, String>>();  
            TreeMap<String, String> CompAttr = new TreeMap<String, String>();    

我想要的输出是：

[A={a={fill=yes, shape=square, size=very large}}]
[B={b={fill=yes, shape=square, size=very large}}]

但我有一个：

[A={a={fill=yes, shape=square, size=very large},b ={fill=yes, shape=square, size=very large},c={fill=yes, shape=square, size=very large}}]

所有内容都存储在A中。如何解决此问题

多谢各位

解决了

        for(String figureName : problem.getFigures().keySet()) {  //Iterates through the Name of figures as A, B, C, 1...6
        RavensFigure thisFigure = problem.getFigures().get(figureName);
        TreeMap<String, TreeMap<String, TreeMap<String, String>>> squareRPM = new TreeMap<String, TreeMap<String, TreeMap<String, String>>>(); //Everytime it changes object create a new squareRPM    

        for(String objectName : thisFigure.getObjects().keySet()) { //Iterates through components in each A, B, C Ex.  A a 
        RavensObject thisObject = thisFigure.getObjects().get(objectName);
        TreeMap<String, TreeMap<String, String>> component = new TreeMap<String, TreeMap<String, String>>();  
        TreeMap<String, String> CompAttr = new TreeMap<String, String>();    

        for(String attributeName : thisObject.getAttributes().keySet()) {  //Iterates through attributes 
        String attributeValue = thisObject.getAttributes().get(attributeName);


        CompAttr.put(attributeName, attributeValue);

        }       
        component.put(objectName, CompAttr);
        squareRPM.put(figureName, component);

for（String figureName:problem.getFigures（）.keySet（））{//遍历图的名称，如A、B、C、1…6
RavensFigure thisFigure=problem.getFigures（）.get（figureName）；
TreeMap squareRPM=new TreeMap（）；//每次它更改对象时创建一个新的squareRPM
for（String objectName:thisFigure.getObjects（）.keySet（））{//遍历每个A、B、C Ex.A中的组件
RavensObject thisObject=thisFigure.getObjects（）.get（objectName）；
TreeMap组件=新的TreeMap（）；
TreeMap CompAttr=新的TreeMap（）；
对于（字符串attributeName:thisObject.getAttributes（）.keySet（））{//遍历属性
字符串attributeValue=thisObject.getAttributes（）.get（attributeName）；
CompAttr.put（attributeName，attributeValue）；
}       
component.put（objectName，compatr）；
平方RPM.put（图名称、部件）；

//

for（条目：squareRPM.entrySet（））{
String key=entry.getKey（）；
TreeMap value=entry.getValue（）；
System.out.println（键+“=>”+值）；
}
}       
}

问题是我在创建每个树映射>

在映射中放置一个映射通常是一个坏主意，因为它会混淆每个人。使用清晰的命名实现自己的类。这些类可以在内部使用其他自定义类的映射（可以再次包含映射）。是的，我曾想过构建类，但我对Java是新手，这是第一次尝试将属性放在一个可以比较它们的位置。我将试试你的建议。非常感谢你！我怀疑它是否能被制造出来。

        for(String figureName : problem.getFigures().keySet()) {  //Iterates through the Name of figures as A, B, C, 1...6
        RavensFigure thisFigure = problem.getFigures().get(figureName);
        TreeMap<String, TreeMap<String, TreeMap<String, String>>> squareRPM = new TreeMap<String, TreeMap<String, TreeMap<String, String>>>(); //Everytime it changes object create a new squareRPM    

        for(String objectName : thisFigure.getObjects().keySet()) { //Iterates through components in each A, B, C Ex.  A a 
        RavensObject thisObject = thisFigure.getObjects().get(objectName);
        TreeMap<String, TreeMap<String, String>> component = new TreeMap<String, TreeMap<String, String>>();  
        TreeMap<String, String> CompAttr = new TreeMap<String, String>();    

        for(String attributeName : thisObject.getAttributes().keySet()) {  //Iterates through attributes 
        String attributeValue = thisObject.getAttributes().get(attributeName);


        CompAttr.put(attributeName, attributeValue);

        }       
        component.put(objectName, CompAttr);
        squareRPM.put(figureName, component);

        for(Entry<String, TreeMap<String, TreeMap<String, String>>> entry : squareRPM.entrySet()) {

              String key = entry.getKey();
              TreeMap<String, TreeMap<String, String>> value = entry.getValue();

              System.out.println(key + " => " + value);

        }
    }       

}
