you can figure out class of your object by calling
getClass method
but you won't be able to do any casting like (????) newObj
however you can use reflection to edit your newObject
using introspection mechanism (or similar)

Hello,
I am creating an instance of an object using Class.newInstance. The
java code I have is as follows:
Object newObj = null;
try
{
newObj = paramTypes[k].newInstance();
}
catch (InstantiationException e)
{
e.printStackTrace(); //To change body of catch statement use File |
Settings | File Templates.
}
Now newObject should be a new object of what ever type parakTypes[k]
is. Which is a parameter passed on to a method. I'm invoking this
method later, but I need to know what kind of object newObject is to
be able to give it a value (through an on-screen editor that will be
added later).
I know I can do an
if (newObj instanceof String)
{
//Code to handle Strings
}
else
{
//Code to handle unknown types.
}
But what I want to do is to be able to figure out the type of
newObject, cast it to that type and edit it before it is used.
So if it is a String, an on-screen dialog box will present itself that
lets input a value from the keyboard, if it is a boolean, a combobox
is sufficient, etc (I dont need the code for the GUI, I know how to do
this :) ).
Very Best Regards,
