java - Static block execution before main method -

-

this question has answer here:

does static block of class execute before main method of same class?

example:

public class example {      static     {         system.out.println("hi");     }      public static void main(string[] args) {          system.out.println("bye");      } }

the output of program :

hi

bye

my doubt why output not:

bye

java run static intializers of class before method called (or instance created). jls, section 12.4.1, states:

a class or interface type t initialized before first occurrence of 1 of following:

  • t class , instance of t created.

  • a static method declared t invoked.

  • a static field declared t assigned.

  • a static field declared t used , field not constant variable (§4.12.4).

  • t top level class (§7.6) , assert statement (§14.10) lexically nested within t (§8.1.3) executed.

part of initialization order is:

  1. next, execute either class variable initializers , static initializers of class, or field initializers of interface, in textual order, though single block.

therefore, static initializer run first, , "hi" printed; main called print "bye".
