Get an object class and instantiate a new instance

Question

I hope to do something like:

SubClass c = var.getClass(); SuperClass varCopy = new SubClass(); 

In other words, I know that the superClass varCopy will be at compile time, but I'm not sure which subclass will be created. Is there any way to do this in Java?

Thanks!

You can do something in this direction.

 Class<? extends SuperClass> clazz = var.getClass(); SuperClass varCopy = clazz.newInstance(); 

Note that clazz.newInstance() will throw an IllegalAccessException if it does not have an empty default constructor.
