java & what does it mean

Java & is a bitwise AND operator, which ANDs the binary bits of two integers or Boolean values ​​bit by bit to return a new integer or Boolean value. It is used to extract binary bits, determine parity, clear specific bits and check set intersection.

Meaning of Java &

Java & is the bitwise AND operator in the Java programming language. It ANDs the binary bits of two integers (or Boolean values) and returns a new integer (or Boolean value).

How the bitwise AND operation works

The bitwise AND operator (&) ANDs the binary bits of two integers (or Boolean values). If both bits are 1, the result is 1; otherwise, the result is 0.

For example:

10 (1010) & 5 (0101) = 4 (0100)

In binary:

1010
& 0101
-----
0100

Use of bitwise AND operation

Bitwise AND operation in Java It has many uses including:

• Extract binary digits: It can be used to get the specific binary digits of a number.
• Determine parity: It can be used to determine whether a number is odd or even (the binary representation of an even number has the last bit 0).
• Clear specific bits: It can be used to set specific binary bits to 0.
• Check Intersection: It can be used to check if there is an intersection between two sets (returns 1 only if both bits are 1).
