]]>JAVA-->关于类的继承的问题http://www.blogjava.net/wufang5/articles/239799.html懒虫懒虫Tue, 11 Nov 2008 02:08:00 GMThttp://www.blogjava.net/wufang5/articles/239799.htmlhttp://www.blogjava.net/wufang5/comments/239799.htmlhttp://www.blogjava.net/wufang5/articles/239799.html#Feedback0http://www.blogjava.net/wufang5/comments/commentRss/239799.htmlhttp://www.blogjava.net/wufang5/services/trackbacks/239799.html 1 先看一个外部类的继承

1 public class FatherClass {
2     public FatherClass(){
3         System.out.println("FatherClass create");
4     }
5 }
6
7

1 public class ChildClass extends FatherClass{
2     public ChildClass(){
3         System.out.println("ChildClass create");
4     }
5     public static void main(String[] args) {
6         FatherClass fc = new FatherClass();
7         ChildClass childClass = new ChildClass();
8     }
9 }
10
11

子类ChildClass是FatherClass的外部继承类，运行ChildClass的结果是

FatherClass create

ChildClass create

2 在来看一个内部类的继承问题

1 public class OuterClass {
2
3     //内部类
4     private class InterClass{
5         public InterClass(){    //内部类的构造函数
6             System.out.println("InterClass create");
7         }
8     }
9
10     //外部类的构造函数
11     public OuterClass(){
12         InterClass in = new InterClass ();
13         System.out.println("OuterClass create");
14     }
15
16     public static void main(String[] args) {
17         OuterClass class1 = new OuterClass();
18     }
19 }
20
21

打印的结果是

InterClass create

OuterClass create
