Could you post code relevant to the problem using the code tags?

Thank you.

You can't call C/C++ code directly from java.

You have to use JNI
http://java.sun.com/...tml/jniTOC.html

or JNA. (This wraps some of the ugliness that is JNI)
https://jna.dev.java.net/

Like skaoth said, you can't call RAW C code from java without those interfaces, but you can run COMPILED executables from Java using the method that you described above.

Please folks read posting carefully... if you do not understand them to not reply
He is not running C code from Java
He is running a .exe from Runtime.exec()

hello everyone
I have question
I need to call c program from java
I don't have problem with application or exe file in c it is working but when I call it from java it doesn't work there is no error but it doesn't work because when I execute the c program the black screen must be appeared so that I can enter the input file and then it produces the output file but in java I cann't see the black screen so please can you tell me the problem
I have used the following code to call c from java:

String line;
			   String output1 = "";
			  
					 Process p = Runtime.getRuntime().exec("cpp.exe");
					 BufferedReader input = new BufferedReader
						   (new InputStreamReader(p.getInputStream()));
					 while ((line = input.readLine()) != null) {
						   output1 += (line + '\n');
					 }
					 input.close();
