Q: If b is 3 and c is 2, what is the result of the expression b >>= c using the compound assignment operator in Java?
D
Answer:
D
Explanation:
In Java, the expression b >>= c is a compound assignment operator that performs a right shift on the variable b by the number of bits specified on the right side of the >>= operator. It is equivalent to the expression b = b >> c.
Here's an example in Java:
<![CDATA[
public class CompoundAssignmentExample {
public static void main(String[] args) {
// Declare variables
int b = 12;
int c = 2;
// Compound assignment (right shift by 2 bits)
b >>= c;
// Display the result
System.out.println("The value of b after b >>= c is: " + b);
}
}
]]>
In this example, if b is initially 12, after the operation, the value of b will be 3. This is because the binary representation of 12 is 1100, and right-shifting it by 2 bits results in 0011, which is 3 in decimal.
