After the execution of the following code, what will be the value of num if the input values are 0 3? (Assume that console is a Scanner object initialized to the standard input device.)

int num = console. nextInt ();

if (num > 0)

num = num + 13;

else

if (num > = 3)

num = num + 15;

a) 0

b) 3

c) 13

d) 15

Option a: 0

Explanation:

Scanner is a Java class used to read a standard input from user. However, the Scanner object nextInt () method can only read an integer per time. If we input 0 3, the first integer will be taken which is 0.

Since the num = 0, the if block will be ignored. Instead, the else block of codes will run. In the else block, the line num = num + 15 will be skipped as well because the if condition is not met. At the end, the num will remain 0.
