Enhanced 'switch' blocks are not supported at language level 7 - Android Studio

I have used a switch statement that takes string values from a spinner. Now, there are a lot of such string values. It looks something like this:

switch (spin.getSelectedItem()) {
    case "first option", "second option", "third option":
         result = 1;
         break;
    case "fourth option", "fifth option", "sixth option":
         result = 2;
         break;
    case "seventh option", "eighth option", "ninth option";
         result = 3;
         break;
}

However, an error appears saying that enhanced switch blocks are not supported at language level 7. I have tried changing the source compatibility and target compatibility in the module settings, but it still doesn't work. Any advice and help is highly appreciated.

The part that isn't supported is this:

case "first option", "second option", "third option":

They are multivalue labels, and are indeed not supported prior to Java 14, where they became standard.

What you need instead is this:

switch (spin.getSelectedItem()) {
    case "first option":
    case "second option":
    case "third option":
        result = 1;
        break;
    /** rest of the code here
}

If you don't have a break keyword after label, the switch by default "falls through" to the next label below it.
