Regarding Clone hierarchy

[DelusionArun]

I am a bit confused over why the following code works:

Assuming main calls var a = new A().clone();

class A extends B implements Cloneable {
public A clone() throws CloneNotSupportedException { return (A) super.clone();}
}

abstract class B{
public B clone() throws CloneNotSupportedException { return (B) super.clone();}
}

Here, class B does not implement Cloneable, yet it works. I am a bit confused over why. Is it enough that either just A or just B has implements Cloneable?

The abstract class B implicitly extends java.lang.Object. It overrides the clone() methods of Object. Any classes can override the clone() method without the need to implement the Cloneable interface, which has an empty body. Hope it clarifies.

I understand now. Thank you for clarifying
