Just trying to figure out how to use many multiple cases for a Java switch statement. Here's an example of what I'm trying to do:
switch (variable)
{
case 5..100:
doSomething();
break;
}
versus having to do:
switch (variable)
{
case 5:
case 6:
etc.
case 100:
doSomething();
break;
}
Any ideas if this possible, or what a good alternative is?
The second option is completely fine. I'm not sure why a responder said it was not possible. This is fine, and I do this all the time:
switch (variable)
{
case 5:
case 6:
etc.
case 100:
doSomething();
break;
}
Maybe not as elegant as some previous answers, but if you want to achieve switch cases with few large ranges, just combine ranges to a single case beforehand:
// make a switch variable so as not to change the original value
int switchVariable = variable;
//combine range 1-100 to one single case in switch
if(1 <= variable && variable <=100)
switchVariable = 1;
switch (switchVariable)
{
case 0:
break;
case 1:
// range 1-100
doSomething();
break;
case 101:
doSomethingElse();
break;
etc.
}
