Regarding instance variable creation & initialization

Question

class A
int a = 1;
class B extends A
int b = 2;
what is the actual sequence of events that take place when an object of B is created?
- creation of instance varaible a for B
- Initialize instance varaible a to default value 0
- change value of a to 1
- creation of instance varaible b for B
- Initialize instance varaible b to default value 0
- change value of b to 2
In particular my question is whether the fields defined for a child class are created only after all the inherited fields are created or all the fields (irrespective of whether inherited or those defined for child class ) are created at the same time?

Answer 1

Run the following:
public class TestInitial {
    public static void main(String[] args) {
        new TestInitialSub();
    private final int a = init("A");
    public TestInitial() {
        super();
        System.out.println("Constructor TestInitial");
        doIt();
    protected void doIt() {
        System.out.println("doIt() a = " + a);
    protected int init(String name) {
        System.out.println("init " + name);
        return 1;
    public static class TestInitialSub extends TestInitial {
        private final int b = init("B");
        public TestInitialSub() {
            super();
            System.out.println("Constructor TestInitialSub");
            doIt();
        @Override
        protected void doIt() {
            System.out.println("doIt() b = " + b);
}
