No, those keywords have to be first in the constructor. Since both keywords can't be first at the same time, you can't use them together.

When you create the constructor, it has to be the first statement. Example: class MyClass public MyClass(){ this(); System.out.println("other stuffs"); } this() is first, if you put the println before this() it'll give you a compilation error. Because of that, you can't have both super() and this() because only 1 can be first public MyClass(){ System.out.println("won't work"); this(); } will give compile error
