JAVA initialization blocks

Question

As some sources say, the Java instance initialization blocks are executed whenever instance is created or right before constructor. But imagine this case:

public         


        

Answer 1

The code is converted by compiler to something like this:

public class Main extends Foo {
  void _init()
  {System.out.println("Main init");}

  public Main()
  {
    super();
    _init();
    {System.out.println("Main constr");}
  }

}

The main rules are:

• super() is called before any initialization code of the current class
• initializer blocks are called before the body of the constructor
