extending

I've been struggling in this area for days now, and I have reached a conclusion, but since the conclusion was not what I was looking for, before I give up, I'll try to see what other people say. Faith dies last... Let's say we have a superclass (called "Super") and a subclass (called "Sub"). class Super { protected static $title = 'super'; public static function get_class_name() { echo __CLASS__; } public static function get_title() { echo self::$title; } } class Sub extends Super { protected static $title = 'sub'; } Now, you would probably expect since Sub extends Super, that Sub would now

So my program has a need of a type of circular ArrayList. Only circular thing about it has to be the get(int index) method, this is the original: /** * Returns the element at the specified position in this list. * * @param index index of the element to return * @return the element at the specified position in this list * @throws IndexOutOfBoundsException {@inheritDoc} */ public E get(int index) { rangeCheck(index); return elementData(index); } If index is -1 it should get the element with index ArrayList.size()-1 and if index is ArrayList.size(), it should get the element with index 0.

Suppose there is a class with all of its constructors declared as private. Eg.: public class This { private This () { } public someMethod( ){ // something here } // some more-- no other constructors } From what I know, making all constructors private is similar to declaring the class "This" as final -- so that it can't be extended. However, the Eclipse messages i'm getting are giving me the impression that this is possible-- an all-constructors-private class can be extended. Take a look at this: When I attempt to extend this class with something like public class That extends This { ... }

I'm following this tutorial on how to extend Python with C\C++ code. The section named "Building the extension module with GCC for Microsoft Windows" fails for me with the following error: fatal error: Python.h: No such file or directory The section named "Building the extension module using Microsoft Visual C++" also fails with a similar error: fatal error C1083: Cannot open include file: 'Python.h': No such file or directory What should I do to solve this? Do you have the python dev files so that you can find Python.h? Do you have the location of Python.h specified to your compiler? with gcc

I am using jQuery v1.8.3 and jQuery UI v1.9.2. I would like to extend an existing jQuery UI widget (in my case the Autocomplete widget) by adding and overriding just some options and methods but keeping the others functionalities as those present in the official release. How can I make that the "proper" (maybe, the "standard") way? P.S. : I searched on the Web ( 1 , 2 , ...) and I found documentation mostly related to creating a new jQuery UI widget but not to extending an existing one. In jQuery UI 1.9+, extending a widget is done in the same manner as creating a new widget. The widget

Im' trying to use the extension "-Xinject-code" of xjc to add some code to my generated classes. For the following simple xsd schema... <?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="MyList" > <xs:complexType> <xs:sequence> <xs:element ref="MyItem" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="MyItem"> <xs:complexType> <xs:sequence> <xs:element name="id" type="xs:int"/> <xs:element name="name" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> ..
