2.         public static void main(String args[]) 

3.         {

4.             double a, b,c;

5.             a = 3.0/0;

6.             b = 0/4.0;

7.             c=0/0.0;

9. 	    System.out.println(a);

10.             System.out.println(b);

13.     }

a) NaN
b) Infinity
c) 0.0
d) all of the mentioned

Answer 1

Answer: d
Explanation: For floating point literals, we have constant value to represent (10/0.0) infinity either positive or negative and also have NaN (not a number for undefined like 0/0.0), but for the integral type, we don’t have any constant that’s why we get an arithmetic exception.
