How do I pass the value instead of the reference of an array?
I think you can use this to copy the value instead of the reference: var b = a.slice(0); EDIT As the comments have mentioned and it’s also mentioned here: https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/slice slice does not alter the original array, but returns a new “one level deep” copy that contains copies of the elements sliced from the original … Read more

Objective-C: Instance Variable in Category

Storing different types of elements in a List in Java
Since the common ancestor of your classes is Object, and because List<? extends Object> does not make things any cleaner (after all, everything extends Object) it looks like List<Object> would be an OK choice. However, such list would be a mixed bag: you would need to check run-time type of the object inside, and make … Read more
Java: For-Each loop and references [duplicate]
Java works a little bit different than many other languages. What o is in the first example is simply a reference to the object. When you say o = new MyObject(), it creates a new Object of type MyObject and references o to that object, whereas before o referenced objects[index]. That is, objects[index] itself is … Read more
