Switch

Question

why does it prints 3 instand of 1?
int x = 0;
int a = 2;
switch(a); {
case 1: ++x;
case 2: ++x;
case 3: ++x;
default: ++x;

}
System.out.println(x);

Answer 1

because there is no break statement.. the value of x will increase till the end unless it finds break or default: case..
now if u add case 4: ++x; case 5: ++x; and then default: case..
the output will be 5
