类初始化

public class House {

 

 

 

 Window w1=new Window(1);

 public House() {

  // TODO Auto-generated constructor stub

 

  print("Hourse()");

  w3=new Window(33);

 }

 Window w2=new Window(2);

 public void f() {

  print("execute f() method");

 }

 Window w3=new Window(3);

 

}





public class Window {

 

 public Window(int marker) {

  // TODO Auto-generated constructor stub

  print("clinit  window("+marker+")");

 }

 

}



public class OrderOfinitialization {

 

 public static void main(String[] args) {

  House house=new House();

  house.f();

 }

}

clinit  window(1)
clinit  window(2)
clinit  window(3)
Hourse()
clinit  window(33)
execute f() method

　　有几点说明

1.变量定义优先任何方法调用(包括构造器)

2.static定义的变量优先执行

3.如果一个类有父类关系，那父类的构造优先执行
