Hi Rancher

I have a class. What I want is to add attributes and there corresponding getter/setter dynamically. Can I do it using reflection. Please give me any hint / tutorial

Thanks

Can you not use the Decorator pattern? Must you actually modify the class itself?

Amir,

Took a look at this explanation of the Decorator Pattern. It's hard to say without knowing what you're trying to achieve, but this may help.

And to answer your original question, no. I don't believe you can dynamically add members to your classes or objects in Java.

You can create classes dynamically at runtime. See BCEL.

You can use reflection to create dynamic proxies too. See this.
