Question

用java 调用python 类里面的方法 怎么调用啊 怎么调用类web 下面的adder方法啊

class web
def getvalue(self,s,v):
self.m=s
self.n=v
def adder(self,a,b):
self.getvalue(3,4)
s=a+self.m
d=b+self.n
return a+b

Answer 1

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
}
