Java quiz 2: Simple conditional statements

Level: Easy

What is written to the standard output as the result of executing the following code?

public class MyClass
  public static void main(String[] args)
    int a = 8;
    int b = 12;
    boolean bool = false;

    if (a < b)
    if (!bool == false)
    if (a + b == 21)
Author: Sar Maroof

Select the correct answer.

Answer explanation

  1. The conditional statement of the first if(a < b) returns true, because a is smaller than b. Therefore X is printed to the standard output.
  2. The conditional statement if(!bool == false) returns false, because the boolean variable bool is false.
  3. The condition if(a + b == 21) returns false because a + b = 8 + 12 = 20.
  4. The last if statement returns false. Therefore the else block is executed and the statement System.out.print(“Z”); writes the letter “Z” to the standard output.

So, the correct answer is d.
