Question

What is the output of the following code snippet?
int x = 5;
int y = 2;
int result = x / y;
System.out.println(result * 2);

a)
5
b)
4
c)

Correct answer is option 'C'. Can you explain this answer?

Answer

Code Explanation:
The given code snippet performs a mathematical operation using the division operator (/) to calculate the result of x divided by y. The value of x is 5 and the value of y is 2. The result of the division operation is then stored in the variable 'result'. Finally, the code prints out the value of 'result' multiplied by 2 using the System.out.println() method.

Code Execution:
To understand the output of the code, let's go through the execution step by step:

1. The variable 'x' is assigned the value 5.
2. The variable 'y' is assigned the value 2.
3. The division operation 'x / y' is performed. Since both 'x' and 'y' are of type 'int', the division operation returns the quotient of the division, which is 2.5.
4. The result of the division operation, 2.5, is stored in the variable 'result'.
5. The code then prints out the value of 'result' multiplied by 2 using the System.out.println() method. The value of 'result' is 2.5, so when multiplied by 2, the output will be 5.0.

Output:
The output of the code snippet will be:
5.0

Explanation:
The answer to this question is option 'C', which is 10. However, this is incorrect. The correct answer is option 'A', which is 5.0.

The reason for this is that when performing arithmetic operations in Java, if both operands are integers, the result will be an integer. In the given code snippet, 'x' and 'y' are both integers, so the division operation 'x / y' will yield an integer result. In this case, the result is 2, since 5 divided by 2 is 2 with a remainder of 1.

When the code prints out the value of 'result' multiplied by 2, it will print out 5.0, not 10.0, because the result is an integer, not a decimal number. However, when the integer 5 is multiplied by 2, it is automatically promoted to a decimal number, resulting in 5.0.

Therefore, the correct output of the code snippet is 5.0.

Answer

The variables x and y are of the int data type, and the division operator (/) performs integer division. The result is 2, and multiplying it by 2 gives 4, making option c the correct choice.
