This code shows how the operators and the operands work in Java.

### Java quiz 21: Working with operators

Level: Easy

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

public class MyClass { static int x = 3; static int y = 7; static boolean isDefect; public static void main(String[] args) { if(x == (y - 4) && !isDefect) { x += 2; y += 3; } if(y == 10 || x == 3) { y += 2; } System.out.print("x" + x + ", y" + y); } }

### Answer explanation

- The first conditional statement if(x == (y – 4) && !isDefect) returns true, because

x = y – 4 = 3 and !isDefect is false. Boolean variables are by default false. - The statement x += 2 increments the value of x by 2. So, x = 3 + 2 = 5 and the statement y += 3 increments the value of y by 3. So, y = 7 + 3 = 10.
- By sequences of if statements the body of all the true statements are executed.
- The statement if(y == 10 || x == 3) also returns true, because y is equal to 10. x is not equal to 3, but by || (OR) operators the statement returns true if one of the operands is true.
- The statement y += 2 increments the value of y by 2. So, y = 10 + 2.

The correct answer is: a.
