从Java转换 [英] converting from Java

问题描述

我有一个Java应用程序，我希望移植到c ++，以便将
与现有的c ++应用程序集成。有没有人知道有任何工具需要帮助？


我发现microsft有一个java-> c＃convert，但java app有类

做多个子类化，这似乎不适用于C＃。

有没有把C＃移植到c ++？

谢谢...查理

I have an application in Java that I would like to port to c++ to
integrate with existing c++ app. Is anyone aware of any tools to help?

I found microsft has a java->c# convert, but the java app has class
that do multiple subclassing and this doesn''t seem to work in C#.
Is there any to port C# to c++?
thanks...charlie

你的意思是托管C ++？您无法将Java移植到本机C ++

即使您的意思是mC ++，也无法自动移植

Java to C ++ AFAIK，因为用C ++表达Java语言和API的更高级别结构并不容易。


您需要什么样的集成？也许你可以使用标准Java或.NET InterOp服务使用JNI

，如果你将Java转换为J＃（只要您的Java代码

符合Java 1.1）。

我发现microsft有一个java-> c＃转换，但java应用程序
有一个类可以进行多个子类化，这不会'' t
似乎适用于C＃。


C＃是Java语言的超集（但是对于Java5中引入的一些

功能），所以你总是可以移植Java

C＃的源代码（对于Java API来说并不总是这样。

调用）。

有没有将C＃移植到c ++？

Do you mean managed C++? You can not port Java to native C++
because most Java features require a VM to be supported.
Even if you mean mC++, there is no way to automatically port
Java to C++ AFAIK because it is far from easy to express the
higher level constructs of the Java language and API in C++.

What kind of integration do you need? Maybe you can use JNI
with standard Java or the .NET InterOp services if you port
Java to J# (which is a breeze as long as your Java code
conforms to Java 1.1).
I found microsft has a java->c# convert, but the java app
has class that do multiple subclassing and this doesn''t
seem to work in C#.
C# is a superset of the Java language (but for some of the
features introduced in Java5), so you can always port Java
source code to C# (this is not always true for Java API
calls).
Is there any to port C# to c++?

不是我知道的。即使用C＃表示的所有内容都可以用C ++表示，也不能保留一些更高级别的b $ b级结构，就像使用Java一样。

Not that I''m aware of. Even if everything that can be
expressed in C# can also be expressed in C++, some higher
level constructs can not be preserved, just like with Java.

我不知道C＃和Java，但是你可以提供一个例子一个无法用C ++表达的Java

结构？

I do not know C# and Java, but may you provide an example of a Java
construct that cannot be expressed in C++?

无法轻易表达匿名内部类。

Anonymous inner classes can''t easily be expressed.
