Scala - Bitwise NOT operator



The Bitwise NOT operator (~) is an unary operator which takes a bit pattern and performs the logical NOT operation on each bit. It is used to invert all of the bits of the operand. It is interesting to note that for any integer x, ~x is the same as -(x + 1).

Bit~ Bit
01
10

The example below describes how bitwise NOT operator works:


  528 -> 00000000000000000000001000010000 (in binary)
        ----------------------------------
 -529 <- 11111111111111111111110111101111 (in binary) 


The code of using Bitwise NOT operator (~) is given below:

object MainObject {
  def main(args: Array[String]) {
    var x = 528

    //Bitwise NOT operation
    var z = ~x

    //Displaying the result
    println("x = " + x)
    println("z = " + z)
  }
}

The output of the above code will be:

x = 528
z = -529
