Question

Is it possible to convert an if statement into a switch statement in java?

Answer 1

First of all, it’s technically a switch block. Second of all, yes it is possible, but extremely unnecessary. However, if you want to do it, here is one way you could make the conversion…

int theCase;
if (someVariable.equals(someString)) {
    theCase = 1;
} else if (someVariable.equals(someOtherString)) {
    theCase = 2;
} else {
    theCase = 3;
}
switch (theCase) {
    case 1:
        //some code here
        break;
    case 2:
        //some code here
        break;
    case 3:
        //some code here
        break;
}

Of course, if you are comparing something other than strings you would use the == operator.

The two are also interchangeable, but only if you’re working with chars or ints and only one condition is being tested.
