public class Switch {

public static void main(String[] args) {

final int a = 1;
final int b;
b = 2;
int x = 0;

switch (x) {
case a: // ok
case b: // compiler error

}// end of switch statement

}// end of main method

}// end of class

Hi friends,

in the above problem, I am giving values to the final variables in main method. so, they won't get any default values.

why am i getting error for case b?

Thanks in Advance

look the arguments in the case can only be compile time contants..the error you get is because of violating that rule

if we want to declare a variable as final we've to initialize it too..
of course in that code, there's error while compile-time..
