Q: If a is false and b is true, what is the result of the expression a || b using logical OR in Java?  

The logical OR operator (||) in Java returns true if at least one of the operands is true. In this case, false || true is true because one of the operands (b) is true.

If a is false and b is true, the logical OR operation (a || b) will evaluate to true because only one of the operands needs to be true for the entire expression to be true. Here's an example program:

public class LogicalOrExample {
    public static void main(String[] args) {
        // Example boolean values
        boolean a = false;
        boolean b = true;

        // Using logical OR operator
        boolean result = a || b;

        // Displaying the result
        System.out.println("Result of logical OR: " + result);
    }
}

In this example, the logical OR operation will result in true. Feel free to run this Java program to see the output.
