What, if anything, is wrong with the following code? void test(int x){ switch(x){ case 1: case 2: case 0: default : case 4: } }
was thinking variable x in switch is not declared since it was only visible within the method

What happened when you tried to compile it?

Hi, point 4 in the explanation, the text states
All case labels should be COMPILE TIME CONSTANTS. This means, you can have literals such as 'a', 5, 10, and true or a final variable
. This suggests that
true is a valid case constant. As you cannot switch on a boolean, is this a typo?
Also, very small type in number 3 where the text states
... the following will not compile because 300 cannot...
but the code example switches on 100 and 200 (and not 300).
Kind regards,
Seán.

You are right. As the first bullet states, boolean is not allowed for switch. 300 should indeed be 200. Fixed.
thank you for your feedback!

No problem at all. I think the same typos are in the explanation for enthuware.ocajp.i.v8.2.1196 also.

Yes, it is a common explanation displayed in multiple questions. Fixed in all.
