Correct Answer: Option B
Explanation
The logical AND operator (&&) is used to perform a logical AND operation between two boolean expressions. It returns true only if both operands are true. The logical NOT operator (!) negates a boolean expression. In this case, x && !y is false.
If x is false and y is true, the result of the expression x && !y using logical AND (&&) and logical NOT (!) in Java is false.
Here's a breakdown of the expression:
xisfalse.!yis the logical NOT ofy, which is!trueand evaluates tofalse.- The logical AND (
&&) requires both conditions to betruefor the entire expression to betrue.
Since x is false and !y is also false, the result of the entire expression is false.
Here's an example program:
public class LogicalExample { public static void main(String[] args) { // Example conditions boolean x = false; boolean y = true; // Using logical AND and NOT operators boolean result = x && !y; // Displaying the result System.out.println("Result of logical AND and NOT: " + result); } }
When you run this Java program, it will output "Result of logical AND and NOT: false".
