Java Running Priority

We have an outer class with name FooClass and a UsedClass inside of FooClass as field.
In addition, we have normal 2 block and static two block. We initialize usedClass field while field definition. When we call FooClass constructor,  what is running priority. All classes and output are below.

public class FooClass {
 
 public FooClass() {
  System.out.println("FooClass  constructor");
 }

 {
  System.out.println("normal block before");
 }

 static {
  System.out.println("static block before");
 }

 public UsedClass innerClass = new UsedClass();
 
 {
  System.out.println("normal block after");
 }
 
 static {
  System.out.println("static block after");
 }
 
 public void doSth(){
  innerClass.doSth();
 }
}

public class UsedClass{
 
 public UsedClass() {
  System.out.println("UsedClass constructor");
 }

 public void doSth() {
  System.out.println("UsedClass doSth method");
 }
}

public class Main {
 
 public static void main(String[] args) {
  FooClass foo = new FooClass();
  foo.doSth();
 }
 
}

The output is: 

        static block before
        static block after
        normal block before
        UsedClass constructor
        normal block after
        FooClass  constructor
        UsedClass doSth method
