Switch statement in java

Question

I bumped into a question just now about a switch statement:

int a = 2;
int x = 0;
switch(a){
case 1: ++x;
case 2: ++x;
case 3: ++x;
default: ++x;
}
System.out.print(x);
//output = 3

I understand that x in this case is being pre incremented but why isnt the code done after the case 2 is exicuted?

Answer 1

There aren't any break statements for any of the cases so they will fall through to the next case until one is reached or the switch statement ends.

Answer 2

If break is not used after the case value in switch statement...
all the case values will be executed after the given case value in switch parameter
edit : chaotic beat me 😉😉😉

Answer 3

ChaoticDawg I figured something was up when var a didnt change and the output was greater than 1
