使用Java本机代码或C ++（QT，WxWidgets等）进行平台无关的编程

Question

I am asking myself if it would be easier and more flexible to program a multiplatform application in Java and compile it to native binaries (the way Eclipse was written) or to use a cross-platform C++ framework like QT. Where are the advantages/disadvantages?

Answer 1

You will find less platform specific problems with Java, but:

• Some less commons platforms have C++ compilers/toolkits available but no JRE.
• With C/C++ you can usually access all native resources. With Java that is not always the case.

Answer 2

It depends on your preferences. If you have much experience with C++, then stay to it. Platform-independence alone is not an argument, as Qt does an excellent job on guaranteeing platform-independent code and everybody can recompile a program on another system (that's actually what you want to do with your Java programs, too).

Answer 3

I would just let the JVM do the compiling to native code.

You might assume its better to pre-compile it but for 98% of the time its not, it just harder and more complicated.
