For some reason, I can't access any files in the public dir. Not found error. I'm not putting the public part in the URL, obviously. View the Lovers source code repository on GitHub . Sweet. I fixed this. After reading about Sinatra Configurations , I added this line to my application class: set :root, Lovers.root That worked! 来源: https://stackoverflow.com/questions/4989711/how-to-deploy-a-modular-sinatra-app-to-heroku

is there any benefit of writing public classes for the main method?

断了今生、忘了曾经 提交于 2019-12-06 04:23:44
We can write a java program with one non-public class containing a main method -- it'll compile and run just fine. Why do people make the main class public? Is there any benefit? There is no benefit of making the class public for the sake of it having a main method. That being said, there isn't really much of a reason not to either. Chances are the main class is either going to be very short with few, if any, substantial methods in it, or it's going to be baked into one of the core classes like class Server { public static void main(String[] args) { Server s = new Server(); s.start(); } //

When is using public fields acceptable?

我与影子孤独终老i 提交于 2019-12-06 04:18:13
I have a main class that has a thread pool, which is used by quite a few other classes for performing actions on a database. I currently have a getter method to get the pool which works fine but seems a bit clumsy. Are there any circumstances where it is acceptable to use a public field instead of getter/setter methods? Are there any circumstances where it is acceptable to use a public field instead of getter/setter methods? The main reason that public fields are bad are that they expose the implementation to the outside world. That leads to unwanted coupling; i.e. classes that are overly

Accesing static variable from another class in java

I had a queue implemented as linked list in my multithreaded server. I want to access this queue from another class. Both classes are in the same package. I tried making this queue as public static and accessing it through getter, but without success Can somebody tell me what is the exact problem. This is my code: Queue Declaration: public static Queue<Request> q=new ConcurrentLinkedQueue<Request>(); public static void setQ(Queue<Request> q) { Connection.q = q; } public static Queue<Request> getQ() { return q; } Accesing Queue: Queue<Request> queue=new ConcurrentLinkedQueue<Request>(); queue

How do I get a list of all the public variables I have in a Class? (C#)

六月ゝ 毕业季﹏ 提交于 2019-12-05 22:56:26
I have a class that has A LOT of public variables and I need to be able to get a list of them. Here's an example of my class: public class FeatList: MonoBehaviour { public static Feat Acrobatic = new Feat("Acrobatic", false, ""); public static Feat AgileManeuvers = new Feat("Agile Maneuvers", false, "" ); void Start(){}} Except there are about 100 more variables. Is there any possible way to get all these member variables in one manageable array? Or have I screwed myself over? If by "Variables" you mean class fields (like variables at the class level) you can use reflection to get access, like

Properties vs Public member variables [duplicate]

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: What is the difference between a field and a property in C# I'm a beginning programmer and I've read all about class properties. Books state that properties allow you to indirectly access member variables. Ok, so what makes it any different than just making the field public and accessing it directly? Here's a quote from Learning C# 3.0 by Jesse Liberty: For example, you might want external classes to be able to

What's the best way to expose Java components such as a JButton in an MVC architecture?

非 Y 不嫁゛ 提交于 2019-12-05 19:30:58
I'm currently programming a Blackjack application in Java and it needs to be written in an MVC architecture. I have all my models, views and controllers fully coded and everything works perfectly. However, I'm wondering what the best way of attaching listeners to components is (e.g, a JButton). My current design declares all components in the view that need listeners as public final. It then passes the view to the controller. From there, the controller has full reign to access the components and add action listeners. Code example: public class View extends JFrame { public final JButton myBtn1

How to access parent class's data member from child class, when both parent and child have the same name for the dat member

问题 my scenario is as follows:: class Parent { public: int x; } class Child:public Parent { int x; // Same name as Parent's "x". void Func() { this.x = Parent::x; // HOW should I access Parents "x". } } Here how to access Parent's "X" from a member function of Child. 回答1: Almost got it: this->x = Parent::x; this is a pointer. 回答2: Accessing it via the scope resolution operator will work: x = Parent::x; However, I would question in what circumstances you want to do this. Your example uses public

Saving public files in the internal storage

问题 I have an application that saves files downloaded from a server. These files are not private to my application and should be accessible to other applications as well. I want to know what would be the correct path to save these files when the SD card is ABSENT. For the SD card, there is the well known API - getExternalStorageDirectory() For the application's private data in the internal memory there is - Context.getFilesDir() On some devices, the internal memory is represented by /emmc/.
