Q: Can we create DLLs in java??? if yes How???
Answer: Unfortunately it is impossible. DLL stands for Dynamic Linking Library and
has definite structure inside. DLL is a part of executable code and helps to make an
application for Windows to be more smaller. And more flexible. It is something like
classes but compiled (Java class files are byte codes and JDK compiles them during
the runtime...).
In Java it is not possible to make an executable code. But with third party software
Yes!
See native compilers on our site.
But I didn t hear about creating DLLs.
So my answer is: in Java it is not possible, but with third party applications it is
possible theoretically. Although I do not know any compilers that produce DLLs there
is no limitations to do that....
