Is Constructor Overriding Possible?

Question

What i know is, the compiler writes a default no argument constructor in the byte code. But if we write it ourselves, that constructor is called automatically. Is this pheno

Answer 1

But if we write it ourselves, that constructor is called automatically.

That's not correct. The no-args constructor is called if you call it, and regardless of whether or not you wrote it yourself. It is also called automatically if you don't code an explicit super(...) call in a derived class.

None of this constitutes constructor overriding. There is no such thing in Java. There is constructor overloading, i.e. providing different argument sets.
