Enums – static and instance blocks

Question

You need to know that enum values are static fields which hold instances of that enum type, and initialization order of static fields depends on their position.
See this example

class SomeClass{
    public SomeClass() { System.out.println("creating SomeClass object"); }
}

class StaticTest{
    static{ System.out.println("static block 1"); }
    static SomeClass sc = new SomeClass();
    static{ System.out.println("static block 2"); }

    public static void main(String[] args) {
        new StaticTest();
    }
}

output

static block 1
creating SomeClass object
static block 2

Now since enum values are always placed at start of enum type, they will always be called before any static initialization block, because everything else can only be declared after enum values.
BUT initialization of enum values (which happens at class initialization) their constructors are called and as you said non-static initialization blocks are executed at start of every constructor which is why you see them:

for every enum value
and before any static initialization block.
