chapter:8,self test-15

[dolly shah]

from chapter:8, self test example:15

 
  public class MyBean{
   private java.util.Map params;
   private java.util.List objects;
   private String name;   
 
   public java.util.Map getParams(){return params;}
   public String getName(){return name;}
   public java.util.List getObjects(){return objects;}
 
   

assume "mybean" is an attribute & is of type MyBean

options are:

A ${mybean.name}

B ${mybean["name"]}

C ${mybean.objects.a}

D ${mybean["params"].a}

E ${mybean.params["a"]}

F ${mybean["objects"].a}

why the answers are c & f? What is "a" here.
They have describe: ""a" is not a List property and since "objects" is not a Map ,a lookup won't be performed.

-why we can't use "objects" in [] operator,it is List & in [] you can use List. They have given a specification page:1-64, I read that but still I am not getting it anyways.

Can anyone please help me?
