Question

Short explanation of my problem, I need to parse an object and put its content into a JTree. I know the object can have fields of primitive types, but also other objects. How can I achieve that parsing, is reflection something I should use? I have no clue right now.

The structure would look something like that:

-object1
    |
    fieldname1 = 1256
    |
    fieldname2 = 5623
    |
    object2
    |  |
    |  fieldname1 = 154
    |  |
    |  fieldname2 = 190
    |
    object3
       | 

Any help would be appreciated. Thanks in advance!

Yes, you should use Reflection API to discover object fields, and fill the JTree node values.

Recursively process each object as follows:

• add a node to the tree
• process objects from fields declared in your object’s class (using Class.getDeclaredFields())
• process objects from fields in each superclass of your object (Class.getDeclaredFields() doesn’t return inherited fields)
