It's the Bitwise Complement operator.

an int is a number that is not a decimal

~ x
Returns the complement of x - the number you get by switching each 1 for a 0 and each 0 for a 1. This is the same as -x - 1.
This operator takes a number’s binary, and returns its one’s complement. For this, it flips the bits until it reaches the first 0 from right.

It is actually the Bitwise Complement operator.

It's used as a "reverse" or "opposite" opperation for integers. So say x = 3, and then we do ~x, thats equivalent to -3

Actuall it does this
number = -number - 1
If the number is positive number it will turn it to negative and subtract 1 from it.
If the number is negative number it will turn it into a positive number then subtract 1 from it.
