Explanation
In Java, the bitwise AND operator (&) and the bitwise NOT operator (~) can be used to perform bitwise operations on integers. The bitwise AND operator combines bits where both corresponding bits are 1, and the bitwise NOT operator flips each bit.
Here's an example:
public class BitwiseAndNotExample { public static void main(String[] args) { // Given values int a = 15; // binary: 1111 int b = 7; // binary: 0111 // Bitwise AND operation int andResult = a & ~b; // Display the result System.out.println("Result of bitwise AND and NOT: " + andResult); } }
In this example, the binary representation of 15 is 1111, and the binary representation of 7 is 0111. The bitwise NOT of b (~b) results in 1000. Then, the bitwise AND operation is performed between a and ~b, resulting in 1000, which is 8 in decimal.
This process involves performing a bitwise NOT on b and then performing a bitwise AND with a.
