When you have to programme a piece of code which have several conditions you could do it in the following way: switch(a.name){ case “smith”: CallHim(); break; case “doyle”: SendAMessageToHim(); break; default: throw new WriteNotReachableErrorException();} If you couldn’t use constants as conditions, you will implement the logic in the following way: if(a.name == smithObject.ToString()){ CallHim();}else if(a.name == doyleObject.ToString()){ SendAMessageToHim();}else{ throw new WriteNotReachableErrorException();} But if you think now there is now other possibility to implement the logic, wait! I found recently…<\/p>\nswitch(a.name)
<\/code>{
<\/code> case \"smith\":
CallHim();
<\/code>break;
<\/code> case \"doyle\":
SendAMessageToHim();
break;
default:
throw new WriteNotReachableErrorException();
}<\/code><\/p>\n<\/code>If you couldn’t use constants as conditions, you will implement the logic in the following way: <\/p>\nif(a.name == smithObject.ToString())

<\/code> CallHim();
}
else if(a.name == doyleObject.ToString())
{
SendAMessageToHim();
}
else
{
throw new WriteNotReachableErrorException();
}<\/code><\/p>\n<\/code>But if you think now there is now other possibility to implement the logic, wait! I found recently following code which is doing exactly the same thing:<\/p>\nfor(;;)
{
if(a.name == smithObject.ToString())
<\/code> {
CallHim();
break;
}
if(a.name == doyleObject.ToString())
{
SendAMessageToHim();
break;
}
throw new WriteNotReachableErrorException();
}<\/code><\/p>\n<\/code>I’m not sure if the last version is comprehensible and maintainable. I will go even further, it’s bad code, because there are better constructs (else if) for doing the job, so we don’t need an approximation workaround for the switch-case statement.<\/p>\n","protected":false},"excerpt":{"rendered":"
