下面是一个示例代码，演示了如何在 Java 中执行 Python 脚本：import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;public class RunPythonScript {public static void main(String[] args) {String command = "python /path/to/your/python/script.py";ProcessBuilder process...
importjava.io.BufferedReader;importjava.io.InputStreamReader;publicclassRunPythonScript{publicstaticvoidmain(String[]args){try{ProcessBuilderpb=newProcessBuilder("python","script.py");Processp=pb.start();BufferedReaderreader=newBufferedReader(newInputStreamReader(p.getInputStream()));Stringline;while((l...
writer.close();//执行 Python 脚本,并传递数据文件名作为参数String[] cmd = {"python", "script.py", fileName}; Process p=Runtime.getRuntime().exec(cmd);//读取 Python 脚本的输出结果BufferedReader in =newBufferedReader(newInputStreamReader(p.getInputStream())); String line;while((line = ...
在Java应用程序中调用Python脚本时,可以定期清理资源,释放内存。可以通过在Java程序中定时调用Python脚本,然后关闭Python进程来实现资源的释放: Processprocess=Runtime.getRuntime().exec("python script.py");process.waitFor();process.destroy(); 1. 2. 3. 这样可以及时释放Python进程占用的内存,避免内存溢出问题。
