 1 package com.test.java.classs; 2  3 /** 4  * Created by Administrator on 2015/12/7. 5  * 在类的内部，变量定义的顺序决定了初始化的顺序。 6  * 变量会在任何方法（包含构造器）被调用之前得到初始化 7  */ 8 public class Variable { 9     public static void main(String[] args) {10         House house = new House();11         house.f();12     }13 14 }15 16 class Window{17     public Window(int n) {18         System.out.println("window-"+n);19     }20 }21 22 class House{23     //124     Window w1 = new Window(1);25 26     public House() {27         //428         System.out.println("house()");29         //530         w4 = new Window(44);31         //632         Window w2 = new Window(2);33     }34     //235     Window w3 = new Window(3);36     void f(){37         System.out.println("f()");38     }39     //340     Window w4 = new Window(4);41 42 }

结果：

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