How can i pass a run time object as a constructor parameter of a runtime

object ?
consider the below sequence

HashMap actions = new HashMap();

HashMap models = new HashMap();

actions.put("TestOp","Testing");

// here TestOp is the key and Testing is Class Name.

models.put("TestOp","TestingPart");

// here TestOp is the key and TestingPart is Class Name.and

//Testing part extends Test which is an abstract class.
Object objValue = actions.get("TestOp");

Object objValue1 = models.get("TestOp");

try

{

// I would like to create a statement below like

// Test testObj = new Testing(new (TestingPart))


how can i do this ?

I presume doing

Test testObj = (Test)getClass().getClassLoader().loadClass(objValue.toString()).newInstance();

// will create an object of Testing but how can i pass an object of TestingPart ?
testObj.perform();

}

catch(Exception e)

{

e.printStackTrace();

}


Please help me with suggestions. Thanks in advance for any reply.
