Java Object

• A constructor can’t be overridden in a superclass, because they are non-inherited.
• A constructor can’t be overridden in similar class because both of them would have similar signatures and compiler error would be there.
• When a subclass object is instantiated & a method is called by superclass constructor which in superclass gets overridden, superclass constructor will be calling the subclass methods.

Java Code:

class Super {
    Super(){
        System.out.println("In Super constructor");
        test();
    }
    
    void test() {
        System.out.println("In Super.test()");
    }
}

class Sub extends Super {
    Sub() {
        System.out.println("In Sub constructor");
    }
    
    void test() {       // overrides test() in Super
        System.out.println("In Sub.test()");
    }
}
