java引用jpython的方法樣本_java

本文執行個體講述了java引用jpython的方法。分享給大家供大家參考，具體如下：

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);  }}

希望本文所述對大家java程式設計有所協助。
