• Java Web Application

  - by Mark R

  I am interested in creating a simple web application that will take in user input, convert it to an XML file and send the file to a database. Coding wise I feel I am okay, it is just the general setup and what implementation to use I am a bit unsure of. At the moment I have a JSP page containing a form, the user fills out the form and on submit a get method is sent to a servlet, in the servlet doGet() method the servlet is instantiating a java object and passing it the user inputted data. The java object then writes that data to an XML file and sends it to the database via REST. All I would be interested to know is if this the standard/optimal way of creating such a web application. Any and all feedback is appreciated. Thanks

• What is the rationale for difference between -> and . in c++ ?

  - by Good Person

  I know the difference between the member operator (.) and the member by pointer operator (-). Why did the c++ designers create a different operator for this access? Why can't the compiler figure it out on its own? If you always used a . does any case exist where it is ambiguous whether you mean a member or a member by pointer?

• Are instance initializers good or bad?

  - by berry120

  I personally quite like instance initializers - I use them to assign default values to things such as collections so when writing constructors I don't have to remember to assign them the same default values each time. It seems quite elegant to me - avoids annoying NPE's popping up and avoids duplicate code. A private method doesn't seem as nice because a) it can't assign values to final fields, b) it could be run elsewhere in code and c) the method still needs to be explicitly called at the start of each constructor. However, the flip side with others I have spoken to is that they're confusing, some people reading the code might not understand what they do or when they're called and thus they could cause more problems than they solve. Are proper use of these initializers something to be encouraged or avoided? Or is it an "each to their own" case?

• Is C really a subset of C++?

• Module.new with class_eval

  - by dorelal

  This is a large commit. But I want you to concentrate on this change block. http://github.com/rails/rails/commit/d916c62cfc7c59ab6411407a05b946d3dd7535e9#L2L1304 Even without understanding the full context of the code I am not able to think of a scenario where I would use include Modue.new { class_eval <<-RUBY def foo puts 'foo' end RUBY } Then end result is that in the root context (self just before include Moduel.new) a method call foo has been added. If I take out the Module.new code and if I only leave class_eval in that case also I will have a method called foo in self. What am I missing.

• Regarding Notify()

  - by user1334074

  I was going through threads and I read that ..The notify() method is used to send a signal to one and only one of the threads that are waiting in that same object's waiting pool. The method notifyAll() works in the same way as notify(), only it sends the signal to all of the threads waiting on the object.... Now my query is that if Lets say I have 5 threads and one main thread , so initially the main thread starts and then five other threads start , Now I want to send notification to third thread only , How could it be possible with the use of notify(), since here I am sending notification to third thread only , please advise.
