Q: What is the value of p after the expression p /= 2 is executed in Java?  

In Java, the expression p /= 2 is a compound assignment operator, which divides the value of p by 2 and assigns the result back to p. It is equivalent to the expression p = p / 2.

If p is initially some numeric value, the result of the expression p /= 2 would be:

p = p / 2;

Here's an example in Java:

public class CompoundAssignmentExample {
    public static void main(String[] args) {
        // Declare variable
        double p = 10.0;

        // Compound assignment
        p /= 2;

        // Display the result
        System.out.println("The value of p after p /= 2 is: " + p);
    }
}

In this example, if p is initially 10.0, after the operation, the value of p will be 5.0 (10.0 / 2).
