What is the best way to pass information from java to c++?

Question

I have a java application I need to pass some info to a C++ program. It has been suggested that I use some simple socket programming to do this. Is this the best way? If not

Answer 1

A simple way to do this is using standard input and output:

class MyTest {
    public static void main(String... args) {
        System.out.println("carpet");
    }
} // Java

#include 
#include 
int main() {
    string input;
    std::getline(std::cin, input);
    std::cout << "from java: " << input << std::endl; // output: carpet
} // C++

# start by piping java's output to c++'s input
$ java MyTest | ./my_receive
