如何将java程序的数据传递至python

Answer 1

java程序的数据传递至python：
1、首先建立一个python脚本，名字为：my_utils.py
def adder(a, b):
return a + b
2、java类代码 FirstJavaScript：
import javax.script.*;
import org.python.core.PyFunction;
import org.python.core.PyInteger;
import org.python.core.PyObject;
import org.python.util.PythonInterpreter;

import java.io.*;
import static java.lang.System.*;
public class FirstJavaScript
{
public static void main(String args[])
{
PythonInterpreter interpreter = new PythonInterpreter();
interpreter.execfile("C:\\Python27\\programs\\my_utils.py");
PyFunction func = (PyFunction)interpreter.get("adder",PyFunction.class);

int a = 2010, b = 2 ;
PyObject pyobj = func.__call__(new PyInteger(a), new PyInteger(b));
System.out.println("anwser = " + pyobj.toString());

}//main
}

Answer 2

首先你需要用到需要用到jython.jar java example：
