Explain please the output of this code

Question

int x = 3;
switch(x){
case 1: { x+=x; }
case 3: { x+=x; }
case 5: { x+=x; }
default: { x+=5; }
}
System.out.println(x);
The correct answer is 17

As far as I understand, our case is "3", so x becomes 6; there is no "break;" statement, so switch continues working. Then, x becomes 11, because 6+5 is 11. Where am I making mistake? Help pls

Answer 1

You’re skipping case 5. Since there is no break it will fall through to all cases after that, including case 5

Answer 2

x=3, so switch starts from case 3.
x=6, as there's no break we go to case 5
x=12, next default
x=17.

Answer 3

I got it, guys. Thankyou Ariela 🙄
