java变量的加载顺序

学习编程思想

 public class Variable {
     public static void main(String[] args) {
         House house = new House();
         house.f();
     }

 }

 class Window{
     public Window(int n) {
         System.out.println("window-"+n);
     }
 }

 class House{
     //
     Window w1 = new Window(1);

     public House() {
         //
         System.out.println("house()");
         //
         w4 = new Window(44);
         //
         Window w2 = new Window(2);
     }
     //
     Window w3 = new Window(3);
     void f(){
         System.out.println("f()");
     }
     //
     Window w4 = new Window(4);

 }

结果：

window-1
window-3
window-4
house()
window-44
window-2
f()
