Bitwise Operators - Quiz

The bitwise AND operator (&) in Java performs a bitwise AND operation between the binary representations of two integers. In this case, 4 & 6 is equivalent to 0100 & 0110, resulting in 0010, which is 2 in decimal.

The result of the expression 4 & 6 using the bitwise AND operator in Java is 4.

Here's the explanation:

The bitwise AND operator (&) performs a bitwise AND operation between corresponding bits of two integers. In binary representation:

• 4 in binary is 100.
• 6 in binary is 110.

Performing bitwise AND operation on each pair of corresponding bits:

  100   (4 in binary)
& 110   (6 in binary)
-----
  100   (Result in binary)

Converting the binary result 100 back to decimal gives 4, so 4 & 6 evaluates to 4.

public class BitwiseANDExample {
    public static void main(String[] args) {
        // Perform bitwise AND operation
        int result = 4 & 6;

        // Display the result
        System.out.println("Result of 4 & 6: " + result);
    }
}

In Java, the bitwise OR operator (|) performs a bitwise OR operation on each bit of the operands. If either of the bits is 1, the result bit is set to 1. Here's an example of how you can use the bitwise OR operator in Java:

public class BitwiseORExample {
    public static void main(String[] args) {
        // Given values
        int x = 7; // binary: 0111
        int y = 3; // binary: 0011

        // Bitwise OR operation
        int result = x | y;

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

In this example, the binary representation of x is 0111, and the binary representation of y is 0011. After the bitwise OR operation, the result will be 0111, which is 7 in decimal.

Please note that the leading zeros in the binary representations are often omitted, but I included them for clarity. The | operator performs the OR operation bit by bit, so each corresponding bit in the result will be 1 if at least one of the corresponding bits in the operands is 1.

The bitwise XOR operator (^) in Java performs a bitwise exclusive OR operation between the binary representations of two integers. In this case, 9 ^ 5 is equivalent to 1001 ^ 0101, resulting in 1100, which is 12 in decimal.

The bitwise XOR operator (^) in Java performs a bitwise XOR operation on each bit of the operands. If the bits are different, the result bit is set to 1; otherwise, it's set to 0. Here's an example:

public class BitwiseXORExample {
    public static void main(String[] args) {
        // Given values
        int a = 9; // binary: 1001
        int b = 5; // binary: 0101

        // Bitwise XOR operation
        int result = a ^ b;

        // Display the result
        System.out.println("Result of bitwise XOR: " + result);
    }
}

In this example, the binary representation of 9 is 1001, and the binary representation of 5 is 0101. After the bitwise XOR operation, the result will be 1100, which is 12 in decimal.

Remember, the XOR operator sets a bit to 1 if the corresponding bits in the operands are different.

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.

The left shift operator (<<) in Java shifts the bits of the left operand to the left by the number of positions specified by the right operand. In this case, m << n is equivalent to 00001010 << 00000110, resulting in 010100000000, which is 640 in decimal.

The right shift operator (>>) in Java shifts the bits of the left operand to the right by the number of positions specified by the right operand. In this case, p >> 2 is equivalent to 00011000 >> 2, resulting in 00000011, which is 6 in decimal.

The bitwise XOR assignment operator (^=) in Java performs a bitwise XOR operation between the variable on the left-hand side and the value on the right-hand side and assigns the result to the variable. In this case, b ^= c is equivalent to 00001001 ^ 00000010, resulting in 00001011, which is 11 in decimal.

The bitwise AND assignment operator (&=) in Java performs a bitwise AND operation between the variable on the left-hand side and the value on the right-hand side and assigns the result to the variable. In this case, m &= 7 is equivalent to 00001111 & 00000111, resulting in 00000111, which is 7 in decimal.
