C and Java

**ActionMan** · 02-01-2002

Hey all,
Im working on a project at the moment which will use a java gui but do the problem solving in c.

The way Im planning to do this is by calling the c functions from the java code..
but im not to sure..

does anyone know how this works?
or is there any other way to link the two languages?

thanks,

I haven't yet tried to connect C and Java, but if I want to connect C and Visual Basic/Delphi I normally write a dll in C and put all the C functions in it! then I load the .dll into my VB/Delphi programm and just call the C functions

Because I don't know much about Java I can't say if this is possible, but if it is, it's the best way

In Java there is a so called Native Interface which you can use to use your C-functions. An introduction to this can be found here:

remember Java is completely OOP whereas C doesnt support , but C++ does - why do the code in C anyway - syntax is very similar.

C supports OOP, not as much as C++ but there is nothing that you can't do in C!

The only thing hardly supported is security, but all other stuff like templates,... are supported (you can simulate them)
