java inner class示例，innerclass,如下示例代码，演示如何使

如下示例代码，演示如何使用java的内置类。

package cn.outofmemory.snippets.core;public class InnerClassRef {    public static void main(String[] args) {        InnerClassRef inner1 = new InnerClassRef();        inner1.boat("Athens");        InnerClassRef inner2 = new InnerClassRef();        // Defining references to inner classes:        InnerClassRef.C c = inner2.cont();        InnerClassRef.D d = inner2.to("Thessaloniki");    }    class C {        private int i = 11;        public int value() {            return i;        }    }    class D {        private String str;        D(String whereTo) {            str = whereTo;        }        String readLabel() {            return str;        }    }    public D to(String s) {        return new D(s);    }    public C cont() {        return new C();    }    public void boat(String dest) {        C c = cont();        D d = to(dest);        System.out.println(d.readLabel());    }}

输出：

Athens
