In computer programming or text markup, to hardcode less frequently, hard code is to use an explicit rather than a symbolic name for something that is likely to change at a later time. Such coding is sometimes known as hardcode noun and it is more difficult to change if it later becomes necessary. In most programming languages, it is possible to equate a symbol with a particular name which may also represent a number value.
If the name changes, the symbol stays the same and only the equate line of code needs to be changed to reflect the new name. When the program is recompiled, the new name is picked up wherever the symbol occurs in the code. Although there are search-and-replace tools that can change all occurrences of a given name, program code is very unforgiving in case a small error is introduced, and it is safer to have a single place in which such a change can be made. For this reason, hardcoding is usually a practice to be avoided.

Is it ever a good idea to hardcode values into our applications? Or is it always the right thing to call these types of values dynamically in case they need to change? The question does narrow it down to valueswhich I take to mean magic numbersbut the answer to whether or not they're a good idea is relative to what they're actually used for! I cringe whenever I see statements like command. Why ? Who decided that?
How To Read File From URL In Java?
Was it timing out before, and someone raised the timeout as a hack instead of fixing the underlying performance issue? Or is it actually some known and documented expectation for processing time?
These shouldn't be magic numbers or constants, they should be externalized in a configuration file or database somewhere with a meaningful name, because their optimal value is determined largely or entirely by the environment that the application is running in. Formulas usually tend to be pretty static, such that the nature of the constant values inside isn't really particularly important. Do we care where the 1 or 3 came from? Not really. What you should be doing for this type of scenario is creating a function.
I don't need to know how you came up with the formula but I still need to know what it's for. The key here is of course to have short and simple functions.
This doesn't work for functions with 10 arguments and 30 lines of calculations. Use function composition or constants in that case. This one is always the gray area because it depends on what exactly the value is.
Most of the time, it's these particular magic numbers that are candidates for turning into constants, because that makes the program easier to understand without complicating the program logic.
The only thing is that often your business logic is a lot more convoluted than that, and it might not make sense to start writing out dozens of functions with parameters each.
You're not going to do that, you're going to AttachForm "B" because every single developer who ever has worked or ever will work there is going to know that "B" is the form code for a single taxpayer filing blah blah blah - the form codes are part of the domain itself, they never change, so they're not really magic numbers.
So you have to use constants sparingly in business logic; basically you have to understand whether or not that "magic number" is actually a magic number or if it's a well-known aspect of the domain. If it's domain, then you don't soft-code it unless there's a really good chance it will change. These are never okay to hard-code, as any poor bastard who has ever been hit with the Previous action failed due to error code 46 can tell you. If your language supports it, you should be using an enumeration type.
So, yeah, it's sometimes acceptable practice to hard code stuff. Just don't be lazy about it; it should be a conscious decision rather than plain old sloppy code. This gives us criteria for hard-coding literals. They should be immutable, not hard to type, occurring in one place or context only, and with recognizable meaning.
As an addition to other answers. Use constants for strings when possible. Of course, you don't want to have.The URL class is the gateway to any of the resource available on the internet. A resource can point to a simple file or directory, or it can refer to a more complicated object, such as a query to a database or to a search engine. What is a URL? As many of you must be knowing that Uniform Resource Locator-URL is a string of text that identifies all the resources on Internet, telling us the address of the resource, how to communicate with it and retrieve something from it.
A Simple URL looks like:. The most general however follows three-components system. This article is contributed by Rishabh Mahrsee.

Soft code gets the information dynamically from outside. It is becoz to change the db connectivity settings we need not modify the program. The value of the variable assigned in the code itself is called Hard Coded. To "hardcode" is to write an absolute value not a variable or another dynamic data directly in an application's source code.
It's sometimes necessary for e. Hard code is a code directly assigned to a variable. It is fixed value cannot be changed. Soft code is a code it gives dynamically, it gives runtime. Hard code is the code which is to be used before finalized one. It can be changed by the programmer before going to finalised. Post New Answer. Thanks in Advance.

So, to overcome situations like this, we usually give these changing parameters in properties file. You can create the properties file anywhere in the project, just make sure that you give correct path while loading the file.
Now, let us see, how can we create properties file first of all. Give some meaningful file name. Once the file is created, Open the file, and have some data, can refer below snap.

The exact meaning of this name on the host machine is both protocol dependent and host dependent. The information normally resides in a file, but it could be generated on the fly.
This component of the URL is called the path component. A URL can optionally specify a "port", which is the port number to which the TCP connection is made on the remote host machine. If the port is not specified, the default port for the protocol is used instead. For example, the default port for http is A URL may have appended to it a "fragment", also known as a "ref" or a "reference". The fragment is indicated by the sharp sign character " " followed by more characters. Rather, it indicates that after the specified resource is retrieved, the application is specifically interested in that part of the document that has the tag chapter1 attached to it.
The meaning of a tag is resource specific. An application can also specify a "relative URL", which contains only enough information to reach the resource relative to another URL. If the protocol, host name, or port number is missing, the value is inherited from the fully specified URL. The file component must be specified. The optional fragment is not inherited. It is the responsibility of the caller to encode any fields, which need to be escaped prior to calling URL, and also to decode any escaped fields, that are returned from URL.
Note, the URI class does perform escaping of its component fields in certain circumstances. Since: JDK1. Specifying a port number of -1 indicates that the URL should use the default port for the protocol. If this is the first URL object being created with the specified protocol, a stream protocol handler object, an instance of class URLStreamHandleris created for that protocol: If the application has previously set up an instance of URLStreamHandlerFactory as the stream handler factory, then the createURLStreamHandler method of that instance is called with the protocol string as an argument to create the stream protocol handler.
If this class does not exist, or if the class exists but it is not a subclass of URLStreamHandlerthen the next package in the list is tried.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Thus I want to know if is possible and not a no-sense to be able to configure OAuth2 client properties:. It could be better to add LoadBalancerd capability to Oauth2RestTemplate for replacing following tricks by. No, but you can paste a link in the other project's issue and it will show up here automatically. The token endpoint would have to be covered in the client, so I don't think it makes sense here but might in a Spring Cloud setting. Or is it just in Spring Cloud? Given that the discussion started with EnableOauth2Sso.
Yes, some change would be here since it relates to the client filter. That was way more elegant than loopback trick that I experimented on my POC. Skip to content.
