hi......
Im doing my main project...
im creating an IDE for c,c++,java using java lang...
i need to link the program written, to the c compiler...
any ideas...
then whr can i download the source code for net beans IDE

This link should help you in getting NetBeans IDE sources and explain how to work with them.
A C Compiler would be an external application, so for invoking it you will need to use the Runtime class and process the output, Sorry had mixed it up with JNI when I posted at the start

Thank u......
is there any function in java for executing external application....
can u explain abt runtime classes..

This should be an easy project, until you have to create a command for executing an applet instead of a standalone application.

Also executing packaged-classes might be a bit tricky.

It will help if you ran some batch files (or possibly even shells for a UNIX box) to see what it takes to execute a java class file, or compile a .java file into a .class file.

Running from the command line gives similar results, but it may be easier to see mistakes or organize your commands by using the above method.

Once you've figured that out, look up the Runtime API

You have seriously got to be joking...

Take a look at how Ant handles such things.

I meant creating the GUI layout would be easy.

It will be hard to create plug-ins for the IDE, but depending on the scope of the assignment plugins can be an optional addition to the IDE.

If its a simple IDE that is dedicated to interfacing with a java compiler and runtime (or even certain components of a JDK) then it shouldn't be too bad.

But this is obviously an assumption. Not enough information of the scope of the assignment is given, and if the scope is bigger than I assumed then I agree that this assignment will not be as easy as I originally thought.

Edit: Actually the OP needs the IDE to interface with a c compiler, not java, though the way it would be done is not too different.

what r the files required for compiling java pgm....
is javac and java enough....

are you now telling you haven't even tried to compile anything yet? javac is the compiler, yes. I 'd suggest you first get to learn how that thing works, before you go and try to create an IDE

i thought netbeans is opensource .....
alright i need to know hw can i compile c program from java code
i should call the c compiler from java code.........

which compiler should i install???
and what method i should call...

to compile java code? I'd suggest the standard Java compiler :)

im not asking for java..
im asking for c....
and what method i should call to compile the c program using java code...

ya i must ....
but im trying to find for calling the c compiler...
