If all class extends object why can't they all call clone

Question

class Main {

    public static void main(String[] args) {
        new Cloned().clone();
    }
}

class Cloned implements Cloneable {
}

This gives an error, saying it is protected. None of the subclasses of object can call that method.

Answer 1

because clone() is protected method in the class Object

if you want clone() to be accessed publically, u need to override that method in ur class.

@override
public Object clone()
{
    return super.clone();
}
