使用Java读取方法调用的c++控制台输出

#include <iostream>

void someMethod() {
    // 输出内容
    std::cout << "Hello from C++!" << std::endl;
}

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

public class Main {
    public static void main(String[] args) {
        try {
            // 构建命令行参数和可执行文件路径
            String[] command = {"path_to_cpp_executable"};

            // 启动外部进程
            ProcessBuilder processBuilder = new ProcessBuilder(command);
            Process process = processBuilder.start();

            // 获取进程的输出流
            InputStream inputStream = process.getInputStream();
            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));

            // 读取输出流内容
            String line;
            while ((line = bufferedReader.readLine()) != null) {
                System.out.println(line);
            }

            // 等待进程结束并获取退出状态
            int exitCode = process.waitFor();
            System.out.println("C++ process exited with code " + exitCode);

        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}
