Suppose you try to compile and run the following program:

public class Attempt $\{$

public static void main$($String$[]$ args$)\{$

double taxRate;

System.out.println$($taxRate$)$;

$\}$

$\}$

$$

The code will not compile because taxRate has not been declared.

The code will not compile because taxRate has not been assigned a value.

The code will compile, but will not run because taxRate has not been assigned a value.

The code will compile and run, and $0$ will be printed.

The code will compile and run, and $0\mathrm{.}0$ will be printed.
