window下java调用python脚本并读取Python运行结果

window下java调用python脚本并读取Python运行结果
java 代码如下：import java.io.InputStreamReader;
import java.io.LineNumberReader;

public class TestRunPython {

public static void main(String[] args) {
String result = "";

try {
Process process = Runtime.getRuntime().exec("python C:/Users/s/my.py test中文" );

InputStreamReader ir = new InputStreamReader(process.getInputStream(),"GBK");
LineNumberReader input = new LineNumberReader(ir);
result = input.readLine();
input.close();
ir.close();
// process.waitFor();
} catch (Exception e) {
System.out.println("调用python脚本并读取结果时出错：" + e.getMessage());
}

System.out.println(result);

}

}

Python文件my.py代码如下：

import sys

if __name__ == "__main__":
filename = sys.argv[1]

print (filename)

运行结果：
