Configuring Spring MVC to map GET requests to one method in a controller and OPTIONS requests to another method
With the SimpleUrlHandlerMapping it is not possible specify the http method. Probably you have to use other mapping like the MethodUrlHandlerMapping in the Spring MVC REST project (http://spring-mvc-rest.sourceforge.net/). The way to declare the mappings using the MethodUrlHandlerMapping should be something like this: <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <props> <prop key="GET /hitmycontroller">MyController</prop> <prop key="OPTIONS /hitmycontroller">MyController</prop> </props> </property> </bean> You can see the example in their page: http://spring-mvc-rest.sourceforge.net/introduction.html Look at the par

Can't override method (Flash Builder) - #1065 Variable Override is not defined
I solved it myself, kind of an strange error, but oh well. I had to press the cross icon that says "Remove Launch" and "Remove All Terminated Launches" next to the stop icon in the console tab. I even restarted my PC, tried project>clean, and restarted Flash Builder several times but only that fixed it. I leave this here just in case anyone meets the same error.

Trying to override _beforeSave method and Magento calling both custom method and core method as well
The same question was answered here. The main idea is that if you copied the method from the original class, this line parent::_beforeSave($customer) will call the original method. You can replace that line with Mage_Eav_Model_Entity_Abstract::_beforeSave($customer); thanks @ProxiBlue for the idea.

Override method with different signature
According to java overridding The overriding method has the same name, number and type of parameters, and return type as the method it overrides. An overriding method can also return a subtype of the type returned by the overridden method. This is called a covariant return type. Here your method return type is different so it is not overridding.

Remember open/closed principle and always use inheritance to extend the functionality never modify the base class behavior.

Why can't I override the * method in Ruby?
Yes, this is a limitation of the Ruby grammar. Specifically, you cannot, as sawa points out, use it with an implicit receiver (nor turn into a unary operator): it expects something on the left hand side. All operators are simply methods called on the object referenced before it, but some operators are more equal than others. Most methods accept an implicit receiver, but the one named * doesn't. I opted for o in a similar situation. -- Added later (as I originally commented on 7stud's post): The problem is that the Ruby parser (Yacc grammar + a bunch of methods) simply does not allow a line starting with a * to be parsed such that the * denotes a method call. If a line starts with a *, the only possible parsing is one where the * is the 'splat' operator. This limitation is unique to th

Java method does not override
UPDATE: The signature of the updateItem method is: @Override protected void updateItem(Image image, boolean b) { super.updateItem(image, b); } I posted my original answer too quickly (before I got the same compile error you did). You can have a method like this if you like: public void updateItem(Product item, boolean empty); You just can't annotate it with: @Override Which means you are redefining a method with the exact same signature (name and arguments) from the base class. Alternatively, reverse the generic type arguments: <Image, Product> vs. <Product, Image>

If you would like to override the clean() method and maintain this validation, you must call the parent class’s clean() method. For 2, yes, if data validates properly.

JMockit: How to override already mocked method with a new mock?
It's not clear what exactly happens here; apparently, at runtime some "chained mocking" is occurring. The real problem is that both tests are doing something invalid with the MockUp API: they are mocking the same method in the same class twice in the same test. It is ok to have two different mock-ups for the same class in the same test, as long as they mock different methods/constructors. The resulting behavior is undefined, as JMockit does not support multiple simultaneous mockings of the same method.

Is it reasonable to replace .Equals with a method rather than override it?
Please note - that GetHashCode and Equals should implement the same logic. Namely - objects that are equal should have the same hash code. This is not the case here, where the hash code comes from the Id while equality has nothing to do with the Id. If you override one, you must override both. You can use whatever logic you wish in your domain, but EF and others will probably use the defaults and you must keep them consistent.

Is it possible to override a method with a derived parameter instead of a base one?
but shouldn't this be valid 'logically'? No. Your interface says that the caller can pass in any Ammo - where you're restricting it to require an AmmoBox, which is more specific. What would you expect to happen if someone were to write: Firearm firearm = new ShellWeapon(); firearm.Reload(new Ammo()); ? That should be entirely valid code - so do you want it to blow up at execution time? Half the point of static typing is to avoid that sort of problem. You could make Firearm generic in the type of ammo is uses: public abstract class Firearm<TAmmo> : Weapon where TAmmo : Ammo { public abstract void Reload(TAmmo ammo); } Then: public class ShellWeapon : Firearm<AmmoBox> That may or may not be a useful way of doing things, but it's at least worth considering.

How can I override the toString method of an ArrayList in Java?
You can't override the toString method of ArrayList1. Instead, you can use a utility class that converts an ArrayList to a String the way you want/need. Another alternative would be using Arrays.deepToString(yourList.toArray()). Using Java 8, this can be done very easily: //List<String> list System.out.println(String.join(",", list)); Or if you have a List<Whatever>: System.out.println( list.stream() .map(Whatever::getFieldX()) .collect(Collectors.joining(", ")) ); I'm still against extending ArrayList or similar, is technically possible but I don't see it as a good option. 1 you could extend ArrayList and override the toString but generally that's not a great idea.

@Override on method in subclass "appears" ignored at runtime
All that the @Override annotation does is make the compiler generate an error if there is no corresponding method anywhere in the class inheritance that could be overridden. So it is meant to make sure that your overridden method actually overrides something. If your method from MyRecordService is not called, but the one from the RecordService class, then I would guess that the wrong object is instanciated. So what you have in front of you is an object of type RecordService, not of type MyRecordService. Since you have not provided that part of the code, this is just a guess, based on the fact that your inheritance looks fine.

If you have a Vector<T>, you will be able at compile time to pass any types of Vector<T> to its add method. That is how the interface is designed. So your FourVector is not a real Vector in that respect: either you accept that and don't implement Vector or you can add a runtime check: if (!(v instanceof FourVector)) throw new UnsupportedOperationException("Only FourVector allowed here");

Override observer method in child class
Notification center will notify objects that register themselves to be notified when an event of interest happens. In your case only the parent class is interested in UIApplicationDidBecomeActiveNotification notification because only the parent class has been registered as the observer and not the child class. so only the parent class will be notified when the event of interest happens. [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(appDidBecomeActiveFromBackground) name:UIApplicationDidBecomeActiveNotification object:nil]; In the above notification registration code addObserver:self represents parent class and not child class.

Javascript override of jQuery (or any other object's) method
It doesn't only override anything defined in the prototype, it actually replaces it. The $.fn property is a copy of the prototype for the jQuery object, so $.fn is the actual prototype, i.e. $.fn === jQuery.prototype. You are correct that you can't isolate such a change to your own calls to the object, it would also affect any other code calling the object as long as your change was in effect. However, as jQuery is strictly single threaded, you could change the prototype, use the object and then change the prototype back, and no other code could be affected. As long as you have code running without a break, there are no events handled.

Java override method from another class without inheritance
Where do I have to start? With inheritance. That's the only way that overriding makes any sense. It's not clear why you don't want to use inheritance, but that really is the only way of overriding a method. Whether you use an anonymous class or a named one is irrelevant, but it must extend the class in order to override the method. That's simply the way overriding works in Java. EDIT: The code you've shown in your updated question does use inheritance by creating an anonymous inner class... but it doesn't do what I expect you want it to, because it creates a new object rather than overriding the method on the existing object. Your parameter value is never used.
