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

In simple words if super class has parameterized constructor, you need to explicitly call super(params) in the first line of your child class constructor else implicitly all super class constructors are called untill object class is reachead.
