Thread: Switch case with nested if inside

Can you post the code you are having problems with?

//package
// imports
 
// class
{
   // main
   {
      // switch
      {
         // if statements
      }
   }
}

That's the base for what it should look like.

If i understood you correctly you wish to see an example of a switch being implemented in if-else methods.
If you're trying to decide which is better, know that in practice, they function almost alike, even performance-wise.

Public static void main(String[] args) {
 
int _number;
 
//... a command which will assign an integer into '_number' (_number = 2 for example)
 
    Switch (_number) {
        Case 0 : //What to do when _number == 0 ;
                    //Break;
        Case 1 : //What to do when _number == 1 ;
                    //Break;
        Case 2 : //What to do when _number == 2 ;
                    //Break;
        Default : //What to do when its none of the above
                    //Break;
    }
}

Public static void main(String[] args) {
 
int _number;
 
//... a command which will assign an integer into '_number' (_number = 2 for example)
 
If (_number == 0) { //What to do when _number == 0 ;
}  else if (_number == 1) { //What to do when _number == 1 ;
}  else if (_number == 2) { //What to do when _number == 2 ;
}  else { //What to do when its none of the above
}

You could ofcourse do it like

If (_number == 0) { //What to do when _number == 0 ; }
If (_number == 1) { //What to do when _number == 1 ; }
If (_number == 2) { //What to do when _number == 2 ; }
...

But that wouldn't be as efficient, as it continues checking and comparing, again and again, regardless to the outcome.
