java references jpython's method example

The example in this article shows how java refers to jpython. I will share it with you for your reference as follows:

import java.util.ArrayList;
import java.util.List;
import org.python.core.PyException;
import org.python.core.PyInteger;
import org.python.core.PyObject;
import org.python.util.PythonInterpreter;
public class python {
  public static void main(String []args)throws PyException
  {
    PythonInterpreter interp =new PythonInterpreter();
    System.out.println("Hello, brave new world");
    interp.exec("import sys");
    interp.exec("print sys");
    interp.set("a", new PyInteger(42));
    interp.exec("print 'test='+str(a)");
    interp.exec("x = 2+2");
    PyObject x = interp.get("x");
    System.out.println("x: "+x);
    System.out.println("Goodbye, cruel world");
    interp.exec("import re");
    //interp.exec("print dir(re)");
    interp.exec("t =re.compile('^(0{2}):(IFCSUM):(MANIFEST):')");
    interp.exec(" a = t.search('00:IFCSUM:MANIFEST:').groups()");
    PyObject k = interp.get("a");
    List list = ((List)k.__tojava__(List.class));
    // int ai= ((Integer)a.__tojava__(Integer.class)).intValue();
    System.out.println(k);
    System.out.println(list);
  }
}

I hope this article has been helpful to you in java programming.
