java中如何调用python呢？

java类中直接运行python语句

import org.python.util.PythonInterpreter;
public class FirstJavaScript {
  public static void main(String args[]) {

    PythonInterpreter interpreter = new PythonInterpreter();

    interpreter.exec("days=('mod','Tue','Wed','Thu','Fri','Sat','Sun'); ");
    interpreter.exec("print days[3];");

  }
}
-----运行以上代码，将输出以下信息-----
Thu

java中调用本机python脚本中的函数

//1.建立一个python脚本，名字为: pythonTest.py

def adder(a, b): 
  return a + b 

//建立java代码
import org.python.core.PyFunction;
import org.python.core.PyInteger;
import org.python.core.PyObject;
import org.python.util.PythonInterpreter;

public class TestPython {
  public static void main(String args[]) {

    PythonInterpreter interpreter = new PythonInterpreter();
    interpreter.execfile("D:\\Test\\pythonTest.py");
    PyFunction func = (PyFunction) interpreter.get("adder",
        PyFunction.class);

    int a = 999, b =10;
    PyObject pyobj = func.__call__(new PyInteger(a), new PyInteger(b));
    System.out.println("结果:" + pyobj.toString());
  } 
}
---------------运行以上代码，将输出以下信息------
结果:1009

使用java直接运行python脚本

 //建立脚本 testPython.py

 #open files 
 print 'welcome java265.com' 
 number=[11,22,88] 
 print number 
 number.sort() 
 print number 
 number.append(0) 
 print number 
 print number.count(0) 
 print number.index(5)

//建立java文件
import org.python.util.PythonInterpreter;

public class TestPython {
  public static void main(String args[]) {

    PythonInterpreter interpreter = new PythonInterpreter();
    interpreter.execfile("D:\\test\testPython.py");
  }
}
