Which one of the following recommendations applies to making the longest data sets go down the screen?

A. Structure your data. B. Make sure your data is entered accurately. C. Remember the rules of mathematical precedence. D. Use absolute and relative references appropriately.

Analyze the following code.

``` class Test { public static void main(String[] args) { String s; System.out.println("s is " + s); } }``` a. The program has a compile error because s is not initialized, but it is referenced in the println statement. b. The program has a runtime error because s is not initialized, but it is referenced in the println statement. c. The program has a runtime error because s is null in the println statement. d. The program compiles and runs fine.
