I understand the concept of running field and instance initialzer blocks are run.

What I am confused about is what running instance initializer blocks
The code at line 3 is {System.out.println("setting field");} I see that as a code block but not sure what you mean by "an instance initializer block"

Here's an example illustrating both static and instance initializer blocks:

Output:
I'm a static init block
I'm a static init block too
begin main
I'm an instance init block
I'm an instance init block as well
I'm an instance init block
I'm an instance init block as well
end main


Hope it helps!
Kind regards,
Roel

Thank You very much was too hung up on the code and did not step back to think the events
1) Class loaded
2) Static Blocks run (belong to class)
3) main run
4) main instantiates 2 instances of class causing instance block to be run

And if you want a more complex example (with class and instance variables), check out this thread.
