Which is true about the above statement?
- A. It will not compile.
- B. The value of the variable number will be 808
- C. The value of the variable number will be 0.
- D. A NumberFormatException will be throw.
- E. The value of the variable number will be 808.1
Answer: D
Explanation:
The Integer class value of 0 returns an Integer from given string. But we need to pass string which has correct format for integer otherwise it will throw a NumberFormatException. In this case we have passed string which is not an integer value (since what we passed is fractional number), so option D is correct.
