What will be the output of the program? public class SqrtExample { public static void main(String [] args) { double value = -9.0; System.out.println( Math.sqrt(value)); } }

Q: What will be the output of the program? public class SqrtExample { public static void main(String [] args) { double value = -9.0; System.out.println( Math.sqrt(value)); } }

The sqrt() method returns NaN (not a number) when it's argument is less than zero.

3.0
-3.0
NaN
Compilation fails.

Correct Answer: NaN

Explanation:

The sqrt() method returns NaN (not a number) when it's argument is less than zero.
