I'm aware that some might suggest using polymorphism but I'm using a ...
How would you do this PHP switch statement? Also note that these are much smaller versions, the 1 I need to create will have a lot more values added to it. Version 1: switch ($p) { case 'home': case '': $current_home = 'current'; break; case 'users.online': case 'users.location': case 'users.featu...
Continuing on previous questions (here, and here), I implemented a basic command pattern, created my command classes and coded to an interface, so when any command is used, to call the execute() method. However, I am still finding myself unable to shake those case statements: I am reading each character from a master/decision String, w...
I'm attempting something like the following: switch ($p) { foreach ($modules as $m) { case '"'.$mod.'"': include 'modules/'.$m.'/cases.php'; break; } } but can't get it to work. Is it possible to use a for loop in this manner, inside a switch? ...
Hello, An enum structure declared in its own class is a member variable to the business logic class. That enum basically represents the state of that other class. Although I have revisited the issue several times, replacing, or getting rid of those case statements proves quite frustrating to me. Several business logic methods simple i...
Hello, I have been trying to figure out a way to tag several methods from my base class, so that a client class can call them by tag. The example code is: public class Base { public void method1(){ ..change state of base class } public void method2(){ ..change state of base class } public void m...

UPDATE: The final version of my utility looks like this: StringBuilder b = new StringBuilder(); for(char c : inLetters.toLowerCase().toCharArray()) { switch(c) { case '0': b.append("0"); break; case '1': b.append("1"); break; case '2': case 'a': cas...
I would like to know if there is anyway I can do this without having to do the same If loop in each of the Switch cases since it's a bit repetitive. switch ($val) { case 1: if(!$object->doSomething1()==$goodValue) row .= $object->doSomething(); break; case 2: if(!$object->doSomething2()==$goodValue) row ...

What is the most terse syntax to combine a check for some preconditions with a switch statement? Can I combine an if/else and switch statement? if (!IsValid(text)) { DoSomeLogging(); } else { switch (text) { case "1": DoSomething(); break; case "2" DoSomethingElse(); break; default...
This IS NOT homework, but it is a practice that the teacher gave us to help study for a test. But i will not be turning this in to the teacher. (i'm hoping that is allowed) He wants a user to input a grade and have it assigned a letter grade. It would be easy with if statements, but i can't use ANY! I have to use the switch method. Her...

Hi, the MySQL manual says that a CASE statement (the WHEN part) can contain a statement_list. How much statement is that to be exact? I need to perform a pretty big query which I would like to parametrize. However this also implies that I need to change tables that are being joined. I've read that this cannot be done using CASE statemen...
I have a yes or no question & answer. I would like to ask another yes or no question if yes was the answer. My instructor wants us to use charAt(0) as input for the answer. Is it possible to have a switch statement within another one (like a nested if statement)? Thanks in advance. EDIT: Here is a sample of my pseudo code = displa...

This seems to come up alot in my code, i'm wondering if there is some way of removing the switch statement, or if there is a more elegant way of doing it? public class MetaData { public string AlbumArtist { get; set; } public string AlbumTitle { get; set; } public string Year { get; set; } public string SongTitle { g...
