The super statement that calls the superclass constructor must be the first statement in the superclass's constructor must be the first statement in the subclass's constructor.
The superclass constructor can be accessed in Java by using the special term super and giving the necessary arguments, such as super or super(the Name), as shown in the code below. The inherited instance variables, such as the name instance variable in the Person superclass, are initialized using the actual parameters sent to super.
Subclasses can access the private instance variables of the superclass constructor indirectly by using the public accessor and mutator methods, but they cannot directly access the public methods of the superclass that they extend. Moreover, constructors from the superclass are not passed down to subclass.
When two classes—a superclass and a subclass—define methods with the same name, the method in the subclass takes precedence. It's known as method overriding.
