About switch...

[Rashmi Tambe]

Have a look at following code...

class sw
{
public static void main(String args[])
{

int  i = 5;
switch (i)
{
case 2 :int k = 9; 
System.out.println("2");
break;
case 3: System.out.println(k); //1
}
}
}

at line marked as 1 , compiler complains as
variable k might not have been initialised
I don't understand why?? if k is not visible to case 3 block , it should have given the error...
variable k undefined.
And if it is visible (in scope on case 3 block) then k is initialised , then why the the copiler complains...
thanx in advance.

k would be initialized only the switch statement hits the case2 and k is a local variable so it does not get initialized auto.
