Creating object by name in Java

Question

I am developing an Engine Java application.
I would like to use the ready-to-use buttons but I do not like the toolbar control.
I used the techniques described here: http://resources.arcgis.com/en/help/arcobjects-java/concepts/engine/0001/000100000785000000.htm under the "Control commands without the ToolbarBean" subject but I changed the code a little to look like this:
ICommand c = (ICommand)new ControlsSelectFeaturesTool();
 This works nicely.
Now I would like to create my buttons dynamically by some configuration file.
I would like the software to read the file and create the buttons by the names found in the file.
For example if the string in the file is "Controls.ControlsSelectFeaturesTool" I would like to run something like this:
ICommand c = (ICommand)CreateObject("Controls.ControlsSelectFeaturesTool")

Can somebody explain if this can be done and how?

Thanks

Hi MDruzgala

Thanks for your response.
I already consider this option. I would like the configuration to be able to get any ready-to-use button.
For this I need very long switch.
I am looking for something similar to what ObjectFactory.Create do, this interface is part from the framework library so I cannot use it in Engine.

Well it depends how much buttons you want to dynamically create with this file. If the amount is limited and you as a programmer know which buttons user will define, i would do this like this:
switch(toolName) // toolName is a string from file
{
      case "Controls.ControlsSelectFeaturesTool":
          ICommand c = (ICommand)new ControlsSelectFeaturesTool();
          //more logic etc
          break;
      case "":
          //....
          break;
}

Hope this helps at least a bit.
