What are REST resources and how do they relate to resource names and resource representations? I read a few articles on the subject, but they were too abstract and they left me more confused than I was before. Is the following URL a resource? If it is, what is the name of that resource and what is its representation? http://api.example.com/users.json?length=2&offset=5 The GET response of the URL should look something like: [ { id: 6, name: "John" }, { id: 7, name: "Jane" } ] The reason why articles on REST resources are abstract is because the concept of a REST resource is abstract. It's

Possible Duplicate: Is Java pass by reference? public class myClass{ public static void main(String[] args){ myObject obj = new myObject("myName"); changeName(obj); System.out.print(obj.getName()); // This prints "anotherName" } public static void changeName(myObject obj){ obj.setName("anotherName"); } } I know that Java pass by value, but why does it pass obj by reference in previous example and change it? Eng.Fouad Java always passes arguments by value, NOT by reference. In your example, you are still passing obj by its value, not the reference itself. Inside your method changeName , you are

The phrase "pass by reference" is used by C and C++ developers alike but they appear to be used to mean different things. What exactly is the difference between this equivocal phrase in each language? Joseph Mansfield There are questions that already deal with the difference between passing by reference and passing by value . In essence, passing an argument by value to a function means that the function will have its own copy of the argument - its value is copied. Modifying that copy will not modify the original object. However, when passing by reference, the parameter inside the function

I'm looking at a piece of Java code right now, and it takes a path as a String and gets its URL using URL resource = ClassLoader.getSystemClassLoader().getResource(pathAsString); , then calls String path = resource.getPath() and finally executes new File(path); . Oh, and there are also calls to URL url = resource.toURI(); and String file = resource.getFile() . I'm totally confused right now - mostly because of the terminology, I guess. Can someone please walk me through the differences, or provide a few links to Dummy-proof material? Especially URI to URL and Resource to File ? To me, it feels

There is a lot of confusion about this and I'd like to know, what exactly is the difference between depreciated , deprecated and obsolete , in a programming context, but also in general. I know I could just look at an online dictionary, and I have, even at many, but they don't all agree, or there are differences in what they say. So I decided to just ask here, considering I also want an answer in a programming context. If I understand right, deprecated means it shouldn't be used anymore, because it has been replaced by a better alternative, or just because it has been abandoned. Obsolete means
