I would like to do something like this:
if (condition)
super(foo.class);
else
super(bar.class);
But the super constructor has to be the first in the constructor. Is it possible to do this anyway?

you cannot call the constructor more than once for a one object but you can call it recursively.
In C++, a Copy Constructor may be called for the following cases: 1) When an object of the class is returned by value. 2) When an object of the class is passed (to a function) by value as an argument. 3) When an object is constructed based on another object of the same class.
Yes. Just make sure that the new Object is has all its variables in a decent state regardless of which conditional paths are executed.
Constructor chaining can be done in two ways: Within same class: It can be done using this() keyword for constructors in the same class. From base class: by using super() keyword to call the constructor from the base class.
Assuming you're calling the same superconstructor in both cases and just passing in a different argument, you can just use the conditional operator:
super(condition ? Foo.class : Bar.class);
