The order in which variables are initialized, subclasses, and parent class constructors are called in Java

First, the conclusion.

Subclass constructor, parent class constructor, variable initialization

Paste Code Animcal.java Parent class

public class Animal{    private static int index = 0;    private static String getStaticName()    {        String name = String.format("animal %d" , index++);        System.out.println(name);        return name;    }    private String name = getStaticName();    public Animal()    {        System.out.println("create animal");    }}

Cat.java sub-class

public class Cat extends Animal{    public Cat()    {        System.out.println("create cat");    }}

Main.java

public class Main {    public static void main(String[] args) throws Exception    {        Cat cat = new Cat();    }}

Print results
