Question

Consider the following code:

int a = 20;
int b = 8;
System.out.println(a % b);

What is output?

Answer 1

When the Java program calculates the modulus of 20 by 8, the output is 4 because that is the remainder of the division.

Step-by-step explanation:

The code provided in the question is a simple Java program that calculates the remainder of dividing two integers using the modulus operator (%). The specific operation being performed is a % b, where a is 20 and b is 8.

When we divide 20 by 8, we get a quotient of 2 with a remainder of 4. Therefore, the output of this program when using the modulus operator will be 4, since the modulus operator gives the remainder when one number is divided by another.

The output of the given code is 4. The % operator in Java represents the modulo operation, which calculates the remainder when a is divided by b. In this case, 20 % 8 results in 4 because 8 goes into 20 two times (2 * 8 = 16), leaving a remainder of 4.

Therefore, the System.out.println(a % b) statement will output 4 to the console.
