java调用python脚本的示例

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;public class JavaCallPythonScript {public static void main(String[] args) {// 调用Python脚本的命令String pythonScriptPath = "path/to/your/python/script.py";try {// 创建进程并执行Python脚本Process process = Runtime.getRuntime().exec("python " + pythonScriptPath);// 获取脚本的输出流BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));// 读取脚本的输出内容String line;while ((line = reader.readLine()) != null) {// 处理脚本的输出结果System.out.println(line);}// 等待脚本执行完毕int exitCode = process.waitFor();System.out.println("Python script execution finished with exit code: " + exitCode);} catch (IOException e) {e.printStackTrace();} catch (InterruptedException e) {e.printStackTrace();}}
}

请将上述代码保存为一个Java文件（例如JavaCallPythonScript.java），并将"path/to/your/python/script.py"替换为实际的Python脚本路径。然后编译并运行该Java程序，它将调用指定的Python脚本并打印其输出结果。
