Why is constructor of super class invoked when we declare the object of sub class? (Java)

Question

Consider this code:

class Test {
    Test() {
        System.out.println(\"In constructor of Superclass\");
    }

    int adds(int n1, int n2) {
        ret         


        

Answer 1

Since you are inheriting base class properties into derived class, there may be some situations where your derived class constructor requires some of the base class variables to initialize its variables. So first it has to initialize base class variables, and then derived class variables. That's why Java calls first base class constructor, and then derived class constructor.

And also it doesn't make any sens to initialize child class with out initializing parent class.
