Test time left: 19:22Select the correct answerWhat will be the output of the following Java code?class average { public static void main(String args[]) { double num[] = { 1.9 , 5.4 , 9.5 , 1.2, 5.2 ,0.5}; double result; result = 0; for (int i = 0; i < 6; ++i) result = result + num[i]; System.out.print(result/6); } }Options3.9999999443.3943.94999999999999973.4999999999
Solution
The given Java code calculates the average of the numbers in the array num[].
Here's how it works:
- It initializes an array num[] with the values {1.9, 5.4, 9.5, 1.2, 5.2, 0.5}.
- It initializes a variable result with the value 0.
- It then uses a for loop to iterate over the array num[], adding each element to result.
- After the loop, it divides result by 6 (the number of elements in num[]) to get the average.
- It then prints this average.
Let's calculate the average:
(1.9 + 5.4 + 9.5 + 1.2 + 5.2 + 0.5) / 6 = 23.7 / 6 = 3.9499999999999997
So, the correct answer is 3.9499999999999997.
