結論：JAVA里面的內部類比C++里面的內部類好用

JAVA代碼

1.OutSide.class

2._Main.class

C++代碼

1.OutSide.h

2.._Main.cpp

下面是JAVA代碼

OutSide.class

package ABoutInnerClass;public class OutSide {public int a=1;public static int b=10000;public void print(){System.out.println("OutSide-print called");}public InSide Create(){InSide a=new InSide();return a;}public class InSide{public int c=2;public void print(){System.out.println("InSide-print called");System.out.println("a of OutSide is "+b);System.out.println("OutSide-a is "+a);System.out.println("OutSide-a is "+OutSide.this.a);}} }

_Main.class

package ABoutInnerClass;public class _Main {public static void main(String[] args){OutSide outside=new OutSide();outside.print();OutSide.InSide inside=outside.new InSide();inside.print();OutSide.InSide inside2=outside.Create();inside2.print(); } }

運行結果：

OutSide-print called
InSide-print called
a of OutSide is 10000
OutSide-a is 1
OutSide-a is 1
InSide-print called
a of OutSide is 10000
OutSide-a is 1
OutSide-a is 1

下面是C++代碼

Outside.h

#include <stdio.h>class OutSide { public:int a; static int static_a;OutSide() :a(1){}void print(){printf_s("OutSide-print called\n");}class InSide{public:int b;InSide():b(2){}void print(){printf_s("InSide-print called\n");printf_s("a of OutSide is %d\n", OutSide::static_a);}};InSide* Create(){InSide *a = new InSide();return a;} }; int OutSide::static_a = 1000;
_Main.cpp
#include "Demo.h" #include <string>void main() {OutSide *outside = new OutSide();outside->print();OutSide::InSide *inside = new OutSide::InSide();inside->print();OutSide::InSide *inside2 = outside->Create();inside2->print();getchar();delete inside2;delete outside;delete inside; } 運行結果:

個人覺得C++中內部類用得不是很多，可以分開寫，時代碼變得簡單，可讀性變強
