JAVA程序执行顺序

 1 class A{
 2     static{System.out.println("Class A");}
 3     {System.out.println("Class c");}
 4     public A(){
 5         System.out.println("this class A");
 6     }
 7 }
 8 
 9 public class Test1 extends A{
10     static {System.out.println("class B");}
11     public Test1(){
12         System.out.println("this class B");
13     }
14     {System.out.println("class d");}
15     public static void main(String[] args) {
16         System.out.println("----start ---");
17         new Test1();
18         new Test1();
19         System.out.println("---end---");
20     }
21 }
22 
23 结果为：
24 Class A
25 class B
26 ----start ---
27 Class c
28 this class A
29 class d
30 this class B
31 Class c
32 this class A
33 class d
34 this class B
35 ---end---
