hi every one!
i have 2 applications one on eclipse and the other on VS2010C++, so i want to send parameters from the java code to the other, i just konw how to execute the c++ code from the java code.
what i want is this : send paramters from java code via a methode( not from the keybord) to the c++ one after that exécute the c++ code and get the result from it, so here is my java code :
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.Scanner;
class Program
{
private final Process proc;
private final Thread out, err, in;
public Program(String cmd, OutputStream pOut, OutputStream pErr, InputStream pIn) throws IOException
{
proc = Runtime.getRuntime().exec(cmd);
out = new Transfert(proc.getInputStream(), pOut);
err = new Transfert(proc.getErrorStream(), pErr);
in = new Transfert(pIn, proc.getOutputStream());
System.out.println("le output de lapplication ="+ out);
System.out.println("le input de lapplication ="+ in);
System.out.println("l'erreur de lapplication ="+ err);
out.start();
err.start();
in.start();
}
public void kill()
{
out.interrupt();
err.interrupt();
in.interrupt();
proc.destroy();
}
}
class Transfert extends Thread
{
private final InputStream in;
private final OutputStream out;
public Transfert(InputStream in, OutputStream out)
{
this.in = in;
this.out = out;
}
@Override
public void run()
{
Scanner sc = new Scanner(in);
try
{
while (sc.hasNextLine())
{
out.write((sc.nextLine() + System.lineSeparator()).getBytes());
out.flush();
if (isInterrupted())
break;
}
}
catch (IOException e)
{
System.err.println(e);
}
sc.close();
}
}
public class Test
{
public static void main(String[] args) throws Exception
{
Program prog = new Program("C:\\Division.exe", System.out, System.err, System.in);
// prog.kill();
}
}
and here is my c++ code :
#include <iostream>
int main()
{
int a,b;
std::cout << "a = ";
std::cin >> a;
std::cout << "b = ";
std::cin >> b;
if (b==0)
std::cerr << "Division par zero interdite" << std::endl;
else
std::cout << "a/b = " << (a/b) << std::endl;
return 0;
}
Could you help me with that ???
Thank you very much
