How many objects are created due to inheritance in java?

Question

Let\'s say I have three classes:

class A {
    A() {
        // super(); 
        System.out.println(\"class A\");
    }
}
class B extends A {
    B() {
             


        

Answer 1

Steps of object creation when you call a constructor to create object:

1. Memory allocation using init is done. This init makes a system call to allocate memory for object creation.

2. Then your constructor is called to initialize the object's fields.

3. Then it calls super class constructor (If there's any super class) and Step 1 through 3 repeats.

What you see when you decompile a class file using javap shows different calls to be made. init makes system call to initialize memory allocation but object's field are initialized when constructor's code is run.
