Why invent clone() when you can use the copy constructor?

Question

Java

I do not quite understand why clone is needed to copy an object, if it's faster to use just a copy constructor. Clone also needs to override the method and implement Clonable, when everything in the constructor is two times. I read various articles about object cloning, but I did not find a normal answer to this question. Can someone explain why we need a separate clone method if a copy constructor is available and which of these two methods is better and more relevant in 22?)
