This article describes the method of java referring to jpython. Share it 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 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 will be helpful to everyone's Java programming.
